In general, phase change inks (sometimes referred to as “hot melt inks”) are in the solid phase at ambient temperature, but exist in the liquid phase at the elevated operating temperature of an ink jet printing device. At the jet operating temperature, droplets of liquid ink are ejected from the printing device and, when the ink droplets contact the surface of the recording substrate, either directly or via an intermediate heated transfer belt or drum, they quickly solidify to form a predetermined pattern of solidified ink drops. Phase change inks have also been used in other printing technologies, such as gravure printing, as disclosed in, for example, U.S. Pat. No. 5,496,879 and German Patent Publications DE 4205636AL and DE 4205713AL, the disclosures of each of which are totally incorporated herein by reference.
Phase change inks for color printing typically comprise a phase change ink carrier composition which is combined with a phase change ink compatible colorant. In a specific embodiment, a series of colored phase change inks can be formed by combining ink carrier compositions with compatible subtractive primary colorants. The subtractive primary colored phase change inks can comprise four component dyes, namely, cyan, magenta, yellow and black, although the inks are not limited to these four colors. These subtractive primary colored inks can be formed by using a single dye or a mixture of dyes. For example, magenta can be obtained by using a mixture of Solvent Red Dyes or a composite black can be obtained by mixing several dyes. U.S. Pat. No. 4,889,560, U.S. Pat. No. 4,889,761, and U.S. Pat. No. 5,372,852, the disclosures of each of which are totally incorporated herein by reference, teach that the subtractive primary colorants employed can comprise dyes from the classes of Color Index (C.I.) Solvent Dyes, Disperse Dyes, modified Acid and Direct Dyes, and Basic Dyes. The colorants can also include pigments, as disclosed in, for example, U.S. Pat. No. 5,221,335, the disclosure of which is totally incorporated herein by reference. U.S. Pat. No. 5,621,022, the disclosure of which is totally incorporated herein by reference, discloses the use of a specific class of polymeric dyes in phase change ink compositions.
Phase change inks have also been used for applications such as postal marking, industrial marking, and labelling.
Phase change inks are desirable for ink jet printers because they remain in a solid phase at room temperature during shipping, long term storage, and the like. In addition, the problems associated with nozzle clogging as a result of ink evaporation with liquid ink jet inks are largely eliminated, thereby improving the reliability of the ink jet printing. Further, in phase change ink jet printers wherein the ink droplets are applied directly onto the final recording substrate (for example, paper, transparency material, and the like), the droplets solidify immediately upon contact with the substrate, so that migration of ink along the printing medium is prevented and dot quality is improved.
Compositions suitable for use as phase change ink carrier compositions are known. Some representative examples of references disclosing such materials include U.S. Pat. Nos. 3,653,932, 4,390,369, 4,484,948, 4,684,956, 4,851,045, 4,889,560, 5,006,170, 5,151,120, 5,372,852, 5,496,879, European Patent Publication 0187352, European Patent Publication 0206286, German Patent Publication DE 4205636AL, German Patent Publication DE 4205713AL, and PCT Patent Application WO 94/04619, the disclosures of each of which are totally incorporated herein by reference.

Examples of suitable isocyanates include monoisocyanates, diisocyanates, triisocyanates, copolymers of a diisocyanate, copolymers of a triisocyanate, polyisocyanates (having more than three isocyanate functional groups), and the like, as well as mixtures thereof.

Any suitable reaction condition for making urethane compounds by condensing alcohols with isocyanates can be used to prepare the urethane-substituted compounds. Typically (although not necessarily), the reaction is carried out at elevated temperatures (for example, from about 60 to about 160° C.) in the presence of an optional urethane reaction catalyst, such as dibutyl tin dilaurate, bismuth tris-neodecanoate, cobalt benzoate, lithium acetate, stannous octoate, triethylamine, or the like. In a specific embodiment, the reaction conditions are conducted in an inert atmosphere, such as argon or nitrogen gas or other suitable gases, to prevent oxidizing or yellowing of the reaction products and to prevent undesirable side reactions. The reaction can employ an inert solvent, such as toluene or the like, or can be performed neat (i.e., without a solvent). The mole ratio of reactants is adjusted so that the isocyanate functionalities are completely consumed in the reaction with a slight molar excess of alcohol-substituted colorant typically remaining. The reactants can be added together in any order and/or added to the reaction as physical mixtures. If desired, reaction conditions and the order of the addition of reactants can be controlled for several reasons, such as to provide a controlled exothermic reaction, to tailor the distribution of molecules in the antioxidant-containing material, or the like. When doing these adjustments, the different reactivities to isocyanates of alcohols versus amines can be employed, as well as the different reactivities of the two separate isocyanate groups on IPDI.

Frisch's “Polyurethanes Part 1, Chemistry” published by Interscience of New York, N.Y. in 1962 and Olin Chemicals' LUXATE® IM isophorone diisocyanate technical product information sheet, the disclosures of each of which are totally incorporated herein by reference, which provide further explanation of this chemistry.

To a 500 milliliter round bottom flask with stir magnet was charged 250 grams of 4-aminophenethyl alcohol (obtained from Aceto Corporation, Lake Success, N.Y.) and 15.6 grams of sodium carbonate (obtained from Aldrich Chemical Co., Milwaukee, Wis.). The mixture was heated to 140° C. in an oil bath with stirring. After the mixture was molten, 50 grams of 4-bromo-1,9-N-methyl anthrapyridone (obtained from Hangsu Aolunda High Tech Industry Co. Ltd., Shanghai, China) was added and the temperature of the oil bath was increased to 185° C. while stirring was continued. After 1 hour, the reaction mixture was quenched into 1,500 milliliters of a 0.5 percent solution of HCl in water while stirring. After several hours, the solids were collected by vacuum filtration and washed two additional times in HCl/H 2 O, filtering after each wash. The filtrant (a brown solution) decreased in color as each subsequent wash was performed. The solids were collected and dried in a vacuum oven at 60° C. The spectral strength of the product was determined using a spectrophotographic procedure based on the measurement of the product in solution by dissolving the product in toluene and measuring the absorbance using a Perkin Elmer Lambda 2S UV/VIS spectrophotometer. The spectral strength of the product was measured as about 28,552 mL Absorbance Units per gram at absorption λ max , 544 nanometers.

EXAMPLE XIV
An ink base was prepared by melting, admixing, and filtering the following ingredients:
polyethylene wax (PE 655, obtained from Baker Petrolite, Tulsa, Okla., of the formula CH 3 (CH 2 ) 50 CH 3 ), 42.01 parts by weight; stearyl stearamide wax (KEMAMIDE® S-180, obtained from Crompton Corporation, Greenwich, Conn.), 18.82 parts by weight; tetra-amide resin obtained from the reaction of one equivalent of a C-36 dimer acid obtained from Uniqema, New Castle, Del. with two equivalents of ethylene diamine and UNICID® 700 (obtained from Baker Petrolite, Tulsa, Okla., a long chain hydrocarbon having a terminal carboxylic acid group), prepared as described in Example 1 of U.S. Pat. No. 6,174,937, the disclosure of which is totally incorporated herein by reference, 24.99 parts by weight; urethane resin obtained from the reaction of two equivalents of ABITOL® E hydroabietyl alcohol (obtained from Hercules Inc., Wilmington, Del.) and one equivalent of isophorone diisocyanate, prepared as described in Example 1 of U.S. Pat. No. 5,782,966, the disclosure of which is totally incorporated herein by reference, 8.82 parts by weight; urethane resin that is the adduct of three equivalents of stearyl isocyanate and a glycerol-based alcohol, prepared as described in Example 4 of U.S. Pat. No. 6,309,453, the disclosure of which is totally incorporated herein by reference, 5.21 parts by weight; and NAUGUARD® 445 antioxidant (available from Uniroyal Chemical Co., Middlebury, Conn.), 0.15 parts by weight. Thereafter, 566.4 grams of the ink carrier and 15.0 grams of the colorant prepared in Example II (2.58 percent by weight) were added to a 1 liter beaker and heated in an oven at 135° C. until molten. Subsequently, the beaker was inserted into a heating mantle set to 135° C. and the contents of the beaker were stirred for 45 minutes. The resulting ink was then filtered through a combination of Whatman # 3 and 0.2 micron NAE filters and placed in a Mott filter assembly. Filtration was supported by the addition of 1 percent by weight FILTER-AID, obtained from Fluka Chemika, Switzerland, and proceeded at a temperature of 135° C. until complete after 6 hours. The dynamic viscosity of the inks was measured using a stress-controlled Dynamic Stress Rheometer (DSR) 2000 from Rheometric Scientific (now TA Instruments). Geometry was 40 mm diameter Cone and Plate. A stress of 1 Pascal was constantly maintained during a step-stress experiment, and viscosity data points were gathered at an approximate rate of 0.5 points per second. Each measurement lasted approximately 5 minutes, with an equilibration period of about 80 seconds; subsequently, data measured between 100 and 300 seconds were averaged. The dynamic viscosity of this ink at 140° C. was 10.80 milliPascal seconds. The spectral strength of the ink was determined using a spectrophotographic procedure based on the measurement of the ink in solution by dissolving the ink in toluene and measuring the absorbance using a Perkin Elmer Lambda 2S UV/VIS spectrophotometer. The spectral strength of this ink was measured as about 105 mL Absorbance Units per gram at absorption λ max of 543 nanometers.
EXAMPLE XV
The procedure of Example XIV was repeated except that the amounts of the ink ingredients (weight percent) were changed as follows:
polyethylene wax: 40.77 stearyl stearamide: 18.27 tetra-amide resin: 22.64 first urethane resin: 8.00 second urethane resin: 4.72 antioxidant: 0.13 colorant: 5.47
The dynamic viscosity of this ink at 140° C. was 10.70 milliPascal seconds. The spectral strength of this ink was measured as about 301 mL Absorbance Units per gram at absorption λ max of 543 nanometers. The ink was then cast into ink sticks and allowed to solidify.
COMPARATIVE EXAMPLE A
The procedure of Example XIV was repeated except that an anthraquinone colorant prepared as described in Example 2 of U.S. Pat. No. 6,395,078, the disclosure of which is totally incorporated herein by reference, was used instead of the colorant prepared in Example II and except that the amounts of the ink ingredients (weight percent) were changed as follows:
polyethylene wax: 41.11 stearyl stearamide: 18.41 tetra-amide resin: 25.55 first urethane resin: 8.63 second urethane resin: 5.10 antioxidant: 0.15 colorant: 1.04
The ink thus prepared was cast into ink sticks and allowed to solidify. The dynamic viscosity of this ink at 140° C. was 10.61 mpas. The spectral strength of this ink was measured as about 239 mL Absorbance Units per gram at absorption λ max of 533 nanometers.
Thermal Analysis
Thermal analysis of the inks from Example XV and Comparative Example A was carried out by means of Dynamic Mechanical Analysis (DMA) using a RSA II Solids Analyzer (obtained from Rheometric Scientific) and Differential Scanning Calorimetry (DSC) using a DSC 2920 (obtained from TA Instruments). Dual-cantilever DMA analysis was carried out to measure mechanical properties of the ink samples, such as modulus of elasticity (e.g. Young's Modulus, E), or loss-angle tangent (which is defined to be Loss Modulus E″, divided by Storage Modulus E′), usually as functions of frequency. The measurement can be conducted at different temperatures, which makes it a useful tool in the thermo-mechanical analysis of an ink. In preparation of the measurement, the ink is cast into thin sticks or rods. Each specimen is subsequently inserted into the instrument in such a way that the two ends of the rod rest on a fork-shaped tool connected with a load cell, while a thin tool touches the rod in its center. The upper tool is moved by a special type of actuator with a constant frequency, and the lower tool measures the response of the solid ink material. As a result, the loss angle tangent is measured as a function of temperature. Maxima of this curve can be associated with glass transition temperatures in many cases, and the areas under the maxima of the same curve are a relative measure of sample toughness (high values indicating high toughness). Both values are reported for the ink samples from Example XII and Comparative Example A in the table below.
DSC is a well-known method of thermal analysis, done in a special kind of calorimeter, which in case of a calibrated measurement system is able to determine the heat capacity of a sample by comparing it with a reference. If this calibration is lacking, the method is still of significant analytical use, since it permits the measurement of any heat effects in the sample specimen. In the case of inks, the method can be used to determine heats of fusion (or solidification) and temperatures which are associated with these phase-transition processes. The typical heat flow curve of a phase transition shows one or several maxima (peaks). The temperature of the crossover point of the baseline with the left-flank tangent line of a peak (for heating experiments) is reported as an “onset” temperature T m(onset) of the fusing process. In the case that such a tangent line cannot be readily determined (e.g. several broad, fused maxima of the curve), we have instead reported the temperatures of the peak maxima T m(max) in the table. In addition, the specific heat of fusion ΔH m (in J/g) was calculated by integration of the area under the peak. Since glass transitions manifest themselves as step-shaped patterns in heat capacity-temperature (or heat-flow-temperature) curves, DSC offers a convenient way to determine an estimate for glass transition temperatures and intervals. In the table, the temperature of the point of inflection of such a step-shaped curve is reported as glass transition temperature T g . The results were as follows:
Comparative Ink A Example XV Ink DSC T g 8° C. 12° C. T m1(onset) 76.2° C. 75.3° C. T m1(max) 85.7° C. 85.2° C. T m2(max) 106° C. 106° C. ΔH m (Jg −1 ) 177.0 179.5 DMA T g (according to tan δ) 8° C. 15° C. Area under log (tan δ) 18.3 15.6
These calorimetric data indicate that the inks will exhibit very similar transfix properties. The increase in glass transition temperature is confirmed by dual-cantilever Dynamic Mechanical Analysis. The slightly reduced area under the log(tan δ) curve indicates a simultaneous increase in brittleness. It is believed that this change was not caused by the colorant but by the slightly reduced content of the second urethane resin, which can act as a toughening agent.
Print Performance: Tape Diffusion
The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate prints of different text sizes and resolutions onto HAMMERMILL LASERPRINT® paper. The resulting prints were then partially covered with SCOTCH® brand transparent tape. Some prints were maintained at room temperature and other prints were maintained at 60° C. After 5 days, the prints were inspected. Whereas the characters generated with the Comparative Example A ink and maintained at 60° C. appeared blurred, the characters generated with the Example XV ink and maintained at 60° C. were clearly legible.
To assess the result of this test in numbers, a comparative qualitative scale ranging from −3.0 to +3.0 was defined. On this scale, negative values indicated undesirable performance and inferiority with respect to the reference sample (that of Comparative Example A, which by itself therefore was rated to be ±0.0), and positive values indicated a desirable performance and hence superiority with respect to the reference sample. For the purpose of number assessment, all character sizes and print resolutions of the text were combined. A 5-day exposure to 60° C. (accelerated test) led to a comparative subjective rating of +2.5 for the prints generated with the ink of Example XV. In comparison, the diffusion process was significantly slower at room temperature, which immediately after the end of the 5-day test led to a lower comparative subjective rating. By estimate, this rating value was located between +0.5 and +1.0 for a 5-day room temperature exposure. The samples were then kept in storage in a dark location at room temperature for another 2¼ years. An inspection of the samples after this time period showed that the room temperature sample of the reference was totally blurred and illegible, whereas the sample with the ink from Example XV appeared virtually unchanged and legible, increasing its comparative subjective rating to a value very close to +3.0.
Print Performance: Showthrough Diffusion
One disadvantage of some magenta colorants is their relatively rapid diffusion through paper, resulting in discoloration of the rear side of the paper over time. The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate solid fill prints onto HAMMERMILL LASERPRINT® paper. A standard resolution of 355×464 dpi was applied. Shortly after printing, the rear sides of the printed papers were scanned with an ACS Photometer, and the respective L*a*b* coordinates were recorded. Thereafter, some of the prints were maintained at room temperature and some of the prints were maintained at 60° C. In defined time intervals of approximately 1 day, 3 days, 5 days, 10 days, and 30 days as reported in the tables, the same sites on the rear sides of the printed papers were again scanned for their color values, and decolorations were quantified by calculating the ΔE values with respect to the initial scan. To different degrees in different parts of the visible light spectrum, color differences with ΔE values exceeding 1.0 are perceptible to the eye of the average observer. Low ΔE values are desirable. The results were as follows:
a) Room Temperature:
Comparative Example A Example XV Time (Days) ΔE Time (Days) ΔE 0.00 0.00 0.00 0.00 1.02 0.05 0.88 0.09 2.00 0.22 2.93 0.09 4.72 0.66 5.09 0.14 8.77 1.59 9.86 0.13 27.99 5.19 32.87 0.39
b) 60° C.:

The data indicate the superior performance of the ink of Example XV compared to the ink containing the ink of Comparative Example A. Diffusion through the paper was virtually stopped. The difference became clear after 2 days during the room temperature test and within the first 24 hours during the 60° C. test.
Print Performance: Colorant Diffusion into Ink Carrier
Another disadvantage of some magenta colorants is their tendency to diffuse relatively quickly from their ink pixels into neighboring pixels on the front side of prints. This process can lead to undesirable discoloration effects over a period of time. The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer. Into a third reservoir was incorporated the phase change ink carrier described in Example I. Solid fill prints were generated on HAMMERMILL LASERPRINT® paper with both inks by dithering during printing with the colorless phase change ink carrier at a standard resolution of 355×464 dpi and at 20%, 50% and 80% ink coverage. Shortly after printing, the front (printed) sides of the printed papers were scanned with an ACS Photometer, and the respective L*a*b* coordinates were recorded. Thereafter, some of the prints were maintained at room temperature and some of the prints were maintained at 60° C. In defined time intervals of approximately 1 day, 3 days, 5 days, 10 days, and 30 days as indicated in the tables, the same sites on the front sides of the printed papers were again scanned for their color values, and decolorations were quantified by calculating the ΔE values with respect to the initial scan. Low ΔE values are desirable. The results were as follows:

As the data indicate, at room temperature, the ink prepared in Example XV exhibited superior performance at all degrees of ink coverage. The diffusion of dye was minimal and was equal to zero within the error limits of the instrument. The difference became clear after the first 24 hours. At 60° C., the ink prepared in Example XV exhibited superior performance at 20% and 50% ink coverage, although not at 80% coverage.
Print Performance: Fingerprint Diffusion
The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate solid fill prints onto HAMMERMILL LASERPRINT® paper. Resolutions of 355×464 dpi and 600×600 dpi were applied. Horizontal solid-fill stripes of different ink fill were generated, varying from 20% fill to 90% fill in 10% increments. Fingerprint diffusion tests were then carried out on the prints by having a test person rub fingers two times with fragrance-free LUBRIDERM® hand lotion. After each rub, the fingers were dried with a towel. The surfaces of the prints were then contaminated by touching them with the fingers, exerting an equal and moderate pressure. Thereafter, the prints were placed into manila folders with sheets of paper between the samples and maintained at room temperature for five days, after which the prints were inspected for changes. Fingerprints appeared quickly in the prints generated with the ink prepared in Comparative Example A, but were almost not visible in the prints generated with the ink prepared in Example XV. To characterize this result in numbers, a comparative qualitative scale, ranging from −3.0 to +3.0, was established. On this scale, the reference from Comparative Example A was assigned a value of ±0.0. Negative values represented undesirable performance and positive values represented desirable performance superior to the reference. The prints generated with the ink of Example XV were subjectively rated +1.5 for the prints at 355×464 dpi resolution and +2.0 for the prints at 600×600 dpi resolution. These ratings reflect the total impression, gained from all coverages between 20% and 90%, for the same resolution. The samples were then stored in a dark place at room temperature for 2¼ years. After this time period, the samples were inspected again, and it was noted that the prints from Example XV still appeared fresh and unaltered, with almost no fingerprints visible. In contrast, the reference showed a significant amount of fading dye and a speckled appearance of the surface, indicating the presence of a degrading processes.

In general, phase change inks (sometimes referred to as “hot melt inks”) are in the solid phase at ambient temperature, but exist in the liquid phase at the elevated operating temperature of an ink jet printing device. At the jet operating temperature, droplets of liquid ink are ejected from the printing device and, when the ink droplets contact the surface of the recording substrate, either directly or via an intermediate heated transfer belt or drum, they quickly solidify to form a predetermined pattern of solidified ink drops. Phase change inks have also been used in other printing technologies, such as gravure printing, as disclosed in, for example, U.S. Pat. No. 5,496,879 and German Patent Publications DE 4205636AL and DE 4205713AL, the disclosures of each of which are totally incorporated herein by reference.
Phase change inks for color printing typically comprise a phase change ink carrier composition which is combined with a phase change ink compatible colorant. In a specific embodiment, a series of colored phase change inks can be formed by combining ink carrier compositions with compatible subtractive primary colorants. The subtractive primary colored phase change inks can comprise four component dyes, namely, cyan, magenta, yellow and black, although the inks are not limited to these four colors. These subtractive primary colored inks can be formed by using a single dye or a mixture of dyes. For example, magenta can be obtained by using a mixture of Solvent Red Dyes or a composite black can be obtained by mixing several dyes. U.S. Pat. No. 4,889,560, U.S. Pat. No. 4,889,761, and U.S. Pat. No. 5,372,852, the disclosures of each of which are totally incorporated herein by reference, teach that the subtractive primary colorants employed can comprise dyes from the classes of Color Index (C.I.) Solvent Dyes, Disperse Dyes, modified Acid and Direct Dyes, and Basic Dyes. The colorants can also include pigments, as disclosed in, for example, U.S. Pat. No. 5,221,335, the disclosure of which is totally incorporated herein by reference. U.S. Pat. No. 5,621,022, the disclosure of which is totally incorporated herein by reference, discloses the use of a specific class of polymeric dyes in phase change ink compositions.
Phase change inks have also been used for applications such as postal marking, industrial marking, and labelling.
Phase change inks are desirable for ink jet printers because they remain in a solid phase at room temperature during shipping, long term storage, and the like. In addition, the problems associated with nozzle clogging as a result of ink evaporation with liquid ink jet inks are largely eliminated, thereby improving the reliability of the ink jet printing. Further, in phase change ink jet printers wherein the ink droplets are applied directly onto the final recording substrate (for example, paper, transparency material, and the like), the droplets solidify immediately upon contact with the substrate, so that migration of ink along the printing medium is prevented and dot quality is improved.
Compositions suitable for use as phase change ink carrier compositions are known. Some representative examples of references disclosing such materials include U.S. Pat. Nos. 3,653,932, 4,390,369, 4,484,948, 4,684,956, 4,851,045, 4,889,560, 5,006,170, 5,151,120, 5,372,852, 5,496,879, European Patent Publication 0187352, European Patent Publication 0206286, German Patent Publication DE 4205636AL, German Patent Publication DE 4205713AL, and PCT Patent Application WO 94/04619, the disclosures of each of which are totally incorporated herein by reference.

A need also remains for colorant compounds that, when incorporated into phase change inks, enable production of prints that maintain uniform color over long periods of time without unevenness or blotching. In addition, a need remains for colorant compounds that, when incorporated into phase change inks, enable production of prints that retain their original color over long periods of time. Further, a need remains for colorant compounds that, when incorporated into phase change inks, enable production of prints that exhibit reduced sensitivity to image discoloration upon contact with human fingertips. Additionally, a need remains for colorant compounds that can be incorporated into phase change inks in desirably high concentrations. There is also a need for colorant compounds that can be manufactured easily and practically.

Examples of suitable isocyanates include monoisocyanates, diisocyanates, triisocyanates, copolymers of a diisocyanate, copolymers of a triisocyanate, polyisocyanates (having more than three isocyanate functional groups), and the like, as well as mixtures thereof.

Any suitable reaction condition for making urethane compounds by condensing alcohols with isocyanates can be used to prepare the urethane-substituted compounds. Typically (although not necessarily), the reaction is carried out at elevated temperatures (for example, from about 60 to about 160° C.) in the presence of an optional urethane reaction catalyst, such as dibutyl tin dilaurate, bismuth tris-neodecanoate, cobalt benzoate, lithium acetate, stannous octoate, triethylamine, or the like. In a specific embodiment, the reaction conditions are conducted in an inert atmosphere, such as argon or nitrogen gas or other suitable gases, to prevent oxidizing or yellowing of the reaction products and to prevent undesirable side reactions. The reaction can employ an inert solvent, such as toluene or the like, or can be performed neat (i.e., without a solvent). The mole ratio of reactants is adjusted so that the isocyanate functionalities are completely consumed in the reaction with a slight molar excess of alcohol-substituted colorant typically remaining. The reactants can be added together in any order and/or added to the reaction as physical mixtures. If desired, reaction conditions and the order of the addition of reactants can be controlled for several reasons, such as to provide a controlled exothermic reaction, to tailor the distribution of molecules in the antioxidant-containing material, or the like. When doing these adjustments, the different reactivities to isocyanates of alcohols versus amines can be employed, as well as the different reactivities of the two separate isocyanate groups on IPDI.

Frisch's “Polyurethanes Part 1, Chemistry” published by Interscience of New York, N.Y. in 1962 and Olin Chemicals' LUXATE® IM isophorone diisocyanate technical product information sheet, the disclosures of each of which are totally incorporated herein by reference, which provide further explanation of this chemistry.

To a 500 milliliter round bottom flask with stir magnet was charged 250 grams of 4-aminophenethyl alcohol (obtained from Aceto Corporation, Lake Success, N.Y.) and 15.6 grams of sodium carbonate (obtained from Aldrich Chemical Co., Milwaukee, Wis.). The mixture was heated to 140° C. in an oil bath with stirring. After the mixture was molten, 50 grams of 4-bromo-1,9-N-methyl anthrapyridone (obtained from Hangsu Aolunda High Tech Industry Co. Ltd., Shanghai, China) was added and the temperature of the oil bath was increased to 185° C. while stirring was continued. After 1 hour, the reaction mixture was quenched into 1,500 milliliters of a 0.5 percent solution of HCl in water while stirring. After several hours, the solids were collected by vacuum filtration and washed two additional times in HCl/H 2 O, filtering after each wash. The filtrant (a brown solution) decreased in color as each subsequent wash was performed. The solids were collected and dried in a vacuum oven at 60° C. The spectral strength of the product was determined using a spectrophotographic procedure based on the measurement of the product in solution by dissolving the product in toluene and measuring the absorbance using a Perkin Elmer Lambda 2S UV/VIS spectrophotometer. The spectral strength of the product was measured as about 28,552 mL Absorbance Units per gram at absorption λ max , 544 nanometers.

EXAMPLE XIV
An ink base was prepared by melting, admixing, and filtering the following ingredients:
polyethylene wax (PE 655, obtained from Baker Petrolite, Tulsa, Okla., of the formula CH 3 (CH 2 ) 50 CH 3 ), 42.01 parts by weight; stearyl stearamide wax (KEMAMIDE® S-180, obtained from Crompton Corporation, Greenwich, Conn.), 18.82 parts by weight; tetra-amide resin obtained from the reaction of one equivalent of a C-36 dimer acid obtained from Uniqema, New Castle, Del. with two equivalents of ethylene diamine and UNICID® 700 (obtained from Baker Petrolite, Tulsa, Okla., a long chain hydrocarbon having a terminal carboxylic acid group), prepared as described in Example 1 of U.S. Pat. No. 6,174,937, the disclosure of which is totally incorporated herein by reference, 24.99 parts by weight; urethane resin obtained from the reaction of two equivalents of ABITOL® E hydroabietyl alcohol (obtained from Hercules Inc., Wilmington, Del.) and one equivalent of isophorone diisocyanate, prepared as described in Example 1 of U.S. Pat. No. 5,782,966, the disclosure of which is totally incorporated herein by reference, 8.82 parts by weight; urethane resin that is the adduct of three equivalents of stearyl isocyanate and a glycerol-based alcohol, prepared as described in Example 4 of U.S. Pat. No. 6,309,453, the disclosure of which is totally incorporated herein by reference, 5.21 parts by weight; and NAUGUARD® 445 antioxidant (available from Uniroyal Chemical Co., Middlebury, Conn.), 0.15 parts by weight. Thereafter, 566.4 grams of the ink carrier and 15.0 grams of the colorant prepared in Example II (2.58 percent by weight) were added to a 1 liter beaker and heated in an oven at 135° C. until molten. Subsequently, the beaker was inserted into a heating mantle set to 135° C. and the contents of the beaker were stirred for 45 minutes. The resulting ink was then filtered through a combination of Whatman # 3 and 0.2 micron NAE filters and placed in a Mott filter assembly. Filtration was supported by the addition of 1 percent by weight FILTER-AID, obtained from Fluka Chemika, Switzerland, and proceeded at a temperature of 135° C. until complete after 6 hours. The dynamic viscosity of the inks was measured using a stress-controlled Dynamic Stress Rheometer (DSR) 2000 from Rheometric Scientific (now TA Instruments). Geometry was 40 mm diameter Cone and Plate. A stress of 1 Pascal was constantly maintained during a step-stress experiment, and viscosity data points were gathered at an approximate rate of 0.5 points per second. Each measurement lasted approximately 5 minutes, with an equilibration period of about 80 seconds; subsequently, data measured between 100 and 300 seconds were averaged. The dynamic viscosity of this ink at 140° C. was 10.80 milliPascal seconds. The spectral strength of the ink was determined using a spectrophotographic procedure based on the measurement of the ink in solution by dissolving the ink in toluene and measuring the absorbance using a Perkin Elmer Lambda 2S UV/VIS spectrophotometer. The spectral strength of this ink was measured as about 105 mL Absorbance Units per gram at absorption λ max of 543 nanometers.
EXAMPLE XV
The procedure of Example XIV was repeated except that the amounts of the ink ingredients (weight percent) were changed as follows:
polyethylene wax: 40.77 stearyl stearamide: 18.27 tetra-amide resin: 22.64 first urethane resin: 8.00 second urethane resin: 4.72 antioxidant: 0.13 colorant: 5.47
The dynamic viscosity of this ink at 140° C. was 10.70 milliPascal seconds. The spectral strength of this ink was measured as about 301 mL Absorbance Units per gram at absorption λ max of 543 nanometers. The ink was then cast into ink sticks and allowed to solidify.
COMPARATIVE EXAMPLE A
The procedure of Example XIV was repeated except that an anthraquinone colorant prepared as described in Example 2 of U.S. Pat. No. 6,395,078, the disclosure of which is totally incorporated herein by reference, was used instead of the colorant prepared in Example II and except that the amounts of the ink ingredients (weight percent) were changed as follows:
polyethylene wax: 41.11 stearyl stearamide: 18.41 tetra-amide resin: 25.55 first urethane resin: 8.63 second urethane resin: 5.10 antioxidant: 0.15 colorant: 1.04
The ink thus prepared was cast into ink sticks and allowed to solidify. The dynamic viscosity of this ink at 140° C. was 10.61 mpas. The spectral strength of this ink was measured as about 239 mL Absorbance Units per gram at absorption λ max of 533 nanometers.
Thermal Analysis
Thermal analysis of the inks from Example XV and Comparative Example A was carried out by means of Dynamic Mechanical Analysis (DMA) using a RSA II Solids Analyzer (obtained from Rheometric Scientific) and Differential Scanning Calorimetry (DSC) using a DSC 2920 (obtained from TA Instruments). Dual-cantilever DMA analysis was carried out to measure mechanical properties of the ink samples, such as modulus of elasticity (e.g. Young's Modulus, E), or loss-angle tangent (which is defined to be Loss Modulus E″, divided by Storage Modulus E′), usually as functions of frequency. The measurement can be conducted at different temperatures, which makes it a useful tool in the thermo-mechanical analysis of an ink. In preparation of the measurement, the ink is cast into thin sticks or rods. Each specimen is subsequently inserted into the instrument in such a way that the two ends of the rod rest on a fork-shaped tool connected with a load cell, while a thin tool touches the rod in its center. The upper tool is moved by a special type of actuator with a constant frequency, and the lower tool measures the response of the solid ink material. As a result, the loss angle tangent is measured as a function of temperature. Maxima of this curve can be associated with glass transition temperatures in many cases, and the areas under the maxima of the same curve are a relative measure of sample toughness (high values indicating high toughness). Both values are reported for the ink samples from Example XII and Comparative Example A in the table below.
DSC is a well-known method of thermal analysis, done in a special kind of calorimeter, which in case of a calibrated measurement system is able to determine the heat capacity of a sample by comparing it with a reference. If this calibration is lacking, the method is still of significant analytical use, since it permits the measurement of any heat effects in the sample specimen. In the case of inks, the method can be used to determine heats of fusion (or solidification) and temperatures which are associated with these phase-transition processes. The typical heat flow curve of a phase transition shows one or several maxima (peaks). The temperature of the crossover point of the baseline with the left-flank tangent line of a peak (for heating experiments) is reported as an “onset” temperature T m(onset) of the fusing process. In the case that such a tangent line cannot be readily determined (e.g. several broad, fused maxima of the curve), we have instead reported the temperatures of the peak maxima T m(max) in the table. In addition, the specific heat of fusion ΔH m (in J/g) was calculated by integration of the area under the peak. Since glass transitions manifest themselves as step-shaped patterns in heat capacity-temperature (or heat-flow-temperature) curves, DSC offers a convenient way to determine an estimate for glass transition temperatures and intervals. In the table, the temperature of the point of inflection of such a step-shaped curve is reported as glass transition temperature T g . The results were as follows:
Comparative Ink A Example XV Ink DSC T g 8° C. 12° C. T m1(onset) 76.2° C. 75.3° C. T m1(max) 85.7° C. 85.2° C. T m2(max) 106° C. 106° C. ΔH m (Jg −1 ) 177.0 179.5 DMA T g (according to tan δ) 8° C. 15° C. Area under log (tan δ) 18.3 15.6
These calorimetric data indicate that the inks will exhibit very similar transfix properties. The increase in glass transition temperature is confirmed by dual-cantilever Dynamic Mechanical Analysis. The slightly reduced area under the log(tan δ) curve indicates a simultaneous increase in brittleness. It is believed that this change was not caused by the colorant but by the slightly reduced content of the second urethane resin, which can act as a toughening agent.
Print Performance: Tape Diffusion
The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate prints of different text sizes and resolutions onto HAMMERMILL LASERPRINT® paper. The resulting prints were then partially covered with SCOTCH® brand transparent tape. Some prints were maintained at room temperature and other prints were maintained at 60° C. After 5 days, the prints were inspected. Whereas the characters generated with the Comparative Example A ink and maintained at 60° C. appeared blurred, the characters generated with the Example XV ink and maintained at 60° C. were clearly legible.
To assess the result of this test in numbers, a comparative qualitative scale ranging from −3.0 to +3.0 was defined. On this scale, negative values indicated undesirable performance and inferiority with respect to the reference sample (that of Comparative Example A, which by itself therefore was rated to be ±0.0), and positive values indicated a desirable performance and hence superiority with respect to the reference sample. For the purpose of number assessment, all character sizes and print resolutions of the text were combined. A 5-day exposure to 60° C. (accelerated test) led to a comparative subjective rating of +2.5 for the prints generated with the ink of Example XV. In comparison, the diffusion process was significantly slower at room temperature, which immediately after the end of the 5-day test led to a lower comparative subjective rating. By estimate, this rating value was located between +0.5 and +1.0 for a 5-day room temperature exposure. The samples were then kept in storage in a dark location at room temperature for another 2¼ years. An inspection of the samples after this time period showed that the room temperature sample of the reference was totally blurred and illegible, whereas the sample with the ink from Example XV appeared virtually unchanged and legible, increasing its comparative subjective rating to a value very close to +3.0.
Print Performance: Showthrough Diffusion
One disadvantage of some magenta colorants is their relatively rapid diffusion through paper, resulting in discoloration of the rear side of the paper over time. The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate solid fill prints onto HAMMERMILL LASERPRINT® paper. A standard resolution of 355×464 dpi was applied. Shortly after printing, the rear sides of the printed papers were scanned with an ACS Photometer, and the respective L*a*b* coordinates were recorded. Thereafter, some of the prints were maintained at room temperature and some of the prints were maintained at 60° C. In defined time intervals of approximately 1 day, 3 days, 5 days, 10 days, and 30 days as reported in the tables, the same sites on the rear sides of the printed papers were again scanned for their color values, and decolorations were quantified by calculating the ΔE values with respect to the initial scan. To different degrees in different parts of the visible light spectrum, color differences with ΔE values exceeding 1.0 are perceptible to the eye of the average observer. Low ΔE values are desirable. The results were as follows:
a) Room Temperature:
Comparative Example A Example XV Time (Days) ΔE Time (Days) ΔE 0.00 0.00 0.00 0.00 1.02 0.05 0.88 0.09 2.00 0.22 2.93 0.09 4.72 0.66 5.09 0.14 8.77 1.59 9.86 0.13 27.99 5.19 32.87 0.39
b) 60° C.:

The data indicate the superior performance of the ink of Example XV compared to the ink containing the ink of Comparative Example A. Diffusion through the paper was virtually stopped. The difference became clear after 2 days during the room temperature test and within the first 24 hours during the 60° C. test.
Print Performance: Colorant Diffusion into Ink Carrier
Another disadvantage of some magenta colorants is their tendency to diffuse relatively quickly from their ink pixels into neighboring pixels on the front side of prints. This process can lead to undesirable discoloration effects over a period of time. The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer. Into a third reservoir was incorporated the phase change ink carrier described in Example I. Solid fill prints were generated on HAMMERMILL LASERPRINT® paper with both inks by dithering during printing with the colorless phase change ink carrier at a standard resolution of 355×464 dpi and at 20%, 50% and 80% ink coverage. Shortly after printing, the front (printed) sides of the printed papers were scanned with an ACS Photometer, and the respective L*a*b* coordinates were recorded. Thereafter, some of the prints were maintained at room temperature and some of the prints were maintained at 60° C. In defined time intervals of approximately 1 day, 3 days, 5 days, 10 days, and 30 days as indicated in the tables, the same sites on the front sides of the printed papers were again scanned for their color values, and decolorations were quantified by calculating the ΔE values with respect to the initial scan. Low ΔE values are desirable. The results were as follows:

As the data indicate, at room temperature, the ink prepared in Example XV exhibited superior performance at all degrees of ink coverage. The diffusion of dye was minimal and was equal to zero within the error limits of the instrument. The difference became clear after the first 24 hours. At 60° C., the ink prepared in Example XV exhibited superior performance at 20% and 50% ink coverage, although not at 80% coverage.
Print Performance: Fingerprint Diffusion
The inks prepared in Example XV and Comparative Example A were each incorporated into different reservoirs of the printhead of a XEROX® PHASER® 850 phase change ink jet printer and used to generate solid fill prints onto HAMMERMILL LASERPRINT® paper. Resolutions of 355×464 dpi and 600×600 dpi were applied. Horizontal solid-fill stripes of different ink fill were generated, varying from 20% fill to 90% fill in 10% increments. Fingerprint diffusion tests were then carried out on the prints by having a test person rub fingers two times with fragrance-free LUBRIDERM® hand lotion. After each rub, the fingers were dried with a towel. The surfaces of the prints were then contaminated by touching them with the fingers, exerting an equal and moderate pressure. Thereafter, the prints were placed into manila folders with sheets of paper between the samples and maintained at room temperature for five days, after which the prints were inspected for changes. Fingerprints appeared quickly in the prints generated with the ink prepared in Comparative Example A, but were almost not visible in the prints generated with the ink prepared in Example XV. To characterize this result in numbers, a comparative qualitative scale, ranging from −3.0 to +3.0, was established. On this scale, the reference from Comparative Example A was assigned a value of ±0.0. Negative values represented undesirable performance and positive values represented desirable performance superior to the reference. The prints generated with the ink of Example XV were subjectively rated +1.5 for the prints at 355×464 dpi resolution and +2.0 for the prints at 600×600 dpi resolution. These ratings reflect the total impression, gained from all coverages between 20% and 90%, for the same resolution. The samples were then stored in a dark place at room temperature for 2¼ years. After this time period, the samples were inspected again, and it was noted that the prints from Example XV still appeared fresh and unaltered, with almost no fingerprints visible. In contrast, the reference showed a significant amount of fading dye and a speckled appearance of the surface, indicating the presence of a degrading processes.
