7.Description:
(en)The present invention relates to novel disulfide dyes, compositions thereof, to processes for their preparation and to their use for the dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or polyamides, especially keratin-containing fibers, cotton or nylon, and preferably hair, more preferably human hair.
It is known, for example, from WO 95/01772 that cationic dyes can be used to dye organic material, for example keratin, silk, cellulose or cellulose derivatives, and also synthetic fibers, for example polyamides. Cationic dyes exhibit very brilliant shades. A disadvantage is their unsatisfactory fastness to washing.
R. S. Asquith, P. Carthew and T. T. Francis describe in JSDC from May 1973, pages 168-172 that ortho-azo disulfide dyes do not lead to covalent bonding with keratin fiber of wool, and that para-azo disulfide dyes underwent only at high concentration some covalent bindings with wool.
The actual technical problem of the present invention was to provide dyes that are distinguished by deep dying having good fastness properties with respect to washing, light, shampooing and rubbing.
Accordingly, the present invention relates to compounds of formula
A-(X 1 ) p —(C sat ) r —S—S—(C sat ) q —(X 2 ) p -D (1)

The at least one disulphide dye may be present in the composition in an amount ranging from 0.001 to 50% relative to the total weight of the composition. In at least one embodiment embodiment, this amount ranges from 0.005 to 20% by weight, such as from 0.01 to 5% by weight relative to the total weight of the composition.
The dyes of formula (1) and (2) according to the invention are suitable for dyeing organic materials, such as keratin-containing fibers, wool, leather, silk, cellulose or polyamides, cotton or nylon, and preferably human hair. The dyeings obtained are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing. The stability, in particular the storage stability of the dyes according to the invention are excellent.
The multiplicity of shades of the dyes can be increased by combination with other dyes.
Therefore the dyes of formula (1) and (2) of the present invention may be combined with dyes of the same or other classes of dyes, especially with direct dyes, oxidation dyes; dye precursor combinations of a coupler compound as well as a diazotized compound, or a capped diazotized compound; and/or cationic reactive dyes.
Direct dyes are of natural origin or may be prepared synthetically. They are uncharged, cationic or anionic, such as acid dyes.
The dyes of formula (1) and (2) may be used in combination with at least one single direct dye different from the dyes of formula (1) and (2).
Examples of direct dyes are described in “Dermatology”, edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basle, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, chapter 7, p. 248-250, and in “Europäisches Inventar der Kosmetikrohstoffe”, 1996, published by The European Commission, obtainable in diskette form from the Bundesverband der deutschen Industrie-und Handelsunternehmen für Arzneimittel, Reformwaren und Körperpflegemittel e.V., Mannheim.
Furthermore, cationic nitroaniline and anthraquinone dyes are useful for a combination with a dye of formula (1) and (2).
The dyes of formula (1) and (2) may also be combined with acid dyes, for example the dyes which are known from the international names (Color index), or trade names.
These acid dyes may be used either as single component or in any combination thereof.
The dyes of formula (1) and (2) may also be combined with uncharged dyes, for example selected from the group of the nitroanilines, nitrophenylenediamines, nitroaminophenols, anthraquinones, indophenols, phenazines, phenothiazines, bispyrazolons, bispyrazol aza derivatives and methines.
Furthermore, the dyes of formula (1) and (2) may also be used in combination with oxidation dye systems.
Oxidation dyes, which, in the initial state, are not dyes but dye precursors are classified according to their chemical properties into developer and coupler compounds.
Suitable oxidation dyes are described for example in
DE 19 959 479, especially in col 2, I. 6 to col 3, I. 11; “Dermatology”, edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basle, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, chapter 8, on p. 264-267 (oxidation dyes).
Preferred developer compounds are for example primary aromatic amines, which are substituted in the para- or ortho-position with a substituted or unsubstituted hydroxy- or amino residue, or diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazol derivatives or 2,4,5,6-tetraaminopyrimidine derivatives.
Furthermore, developer compounds in their physiological compatible acid addition salt form, such as hydrochloride or sulfate can be used. Developer compounds, which have aromatic OH radicals are also suitable in their salt form together with a base, such as alkali metalphenolates.
Preferred developer compounds are disclosed in DE 19959479, p. 2, I. 8-29.
Preferred coupler compounds are m-phenylendiamine derivatives, naphthole, resorcine and resorcine derivatives, pyrazolone and m-aminophenol derivatives, and most preferably the coupler compounds disclosed in DE 19959479, p.1, I. 33 to p. 3, I. 11.
Furthermore, autooxidizable compounds may be used in combination with the dyes of formula (1).
Autooxidizable compounds are aromatic compounds with more than two substituents in the aromatic ring, which have a very low redox potential and will therefore be oxidized when exposed to the air. The dyeings obtained with these compounds are very stable and resistant to shampoo.
Autooxidizable compounds are for example benzene, indole, or indole, especially 5,6-dihydroxyindol or 5,6-dihydroxyindol.
The dyes of formula (1) may also be used in combination with naturally occurring dyes, such as henna red, henna neutral, henna black, camomile blossom, sandalwood, black tea, Rhamnus frangula bark, sage, campeche wood, madder root, catechu, sedre and alkanet root.
Furthermore, the dyes of formula (1) and (2) may also be used in combination with capped diazotized compounds.
Suitable diazotized compounds are for example the compounds of formulae (1)-(4) in WO 2004/019897 (bridging gages 1 and 2) and the corresponding water-soluble coupling components (I)-(IV) as disclosed in the same reference on p. 3 to

7.Description:
(en)The present invention relates to novel disulfide dyes, compositions thereof, to processes for their preparation and to their use for the dyeing of organic materials, such as keratin fibers, wool, leather, silk, cellulose or polyamides, especially keratin-containing fibers, cotton or nylon, and preferably hair, more preferably human hair.
It is known, for example, from WO 95/01772 that cationic dyes can be used to dye organic material, for example keratin, silk, cellulose or cellulose derivatives, and also synthetic fibers, for example polyamides. Cationic dyes exhibit very brilliant shades. A disadvantage is their unsatisfactory fastness to washing.
R. S. Asquith, P. Carthew and T. T. Francis describe in JSDC from May 1973, pages 168-172 that ortho-azo disulfide dyes do not lead to covalent bonding with keratin fiber of wool, and that para-azo disulfide dyes underwent only at high concentration some covalent bindings with wool.
The actual technical problem of the present invention was to provide dyes that are distinguished by deep dying having good fastness properties with respect to washing, light, shampooing and rubbing.
Accordingly, the present invention relates to compounds of formula
A-(X 1 ) p —(C sat ) r —S—S—(C sat ) q —(X 2 ) p -D (1)

The dyes of formula (1) and (2) according to the invention are suitable for dyeing organic materials, such as keratin-containing fibers, wool, leather, silk, cellulose or polyamides, cotton or nylon, and preferably human hair. The dyeings obtained are distinguished by their depth of shade and their good fastness properties to washing, such as, for example, fastness to light, shampooing and rubbing. The stability, in particular the storage stability of the dyes according to the invention are excellent.
The multiplicity of shades of the dyes can be increased by combination with other dyes.
Therefore the dyes of formula (1) and (2) of the present invention may be combined with dyes of the same or other classes of dyes, especially with direct dyes, oxidation dyes; dye precursor combinations of a coupler compound as well as a diazotized compound, or a capped diazotized compound; and/or cationic reactive dyes.

The dyes of formula (1) and (2) may be used in combination with at least one single direct dye different from the dyes of formula (1) and (2).
Examples of direct dyes are described in “Dermatology”, edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basle, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, chapter 7, p. 248-250, and in “Europäisches Inventar der Kosmetikrohstoffe”, 1996, published by The European Commission, obtainable in diskette form from the Bundesverband der deutschen Industrie-und Handelsunternehmen für Arzneimittel, Reformwaren und Körperpflegemittel e.V., Mannheim.
Furthermore, cationic nitroaniline and anthraquinone dyes are useful for a combination with a dye of formula (1) and (2).
The dyes of formula (1) and (2) may also be combined with acid dyes, for example the dyes which are known from the international names (Color index), or trade names.
These acid dyes may be used either as single component or in any combination thereof.

Furthermore, the dyes of formula (1) and (2) may also be used in combination with oxidation dye systems.
Oxidation dyes, which, in the initial state, are not dyes but dye precursors are classified according to their chemical properties into developer and coupler compounds.
Suitable oxidation dyes are described for example in
DE 19 959 479, especially in col 2, I. 6 to col 3, I. 11; “Dermatology”, edited by Ch. Culnan, H. Maibach, Verlag Marcel Dekker Inc., New York, Basle, 1986, Vol. 7, Ch. Zviak, The Science of Hair Care, chapter 8, on p. 264-267 (oxidation dyes).

The application of the dyeing composition is generally carried out at room temperature. It may however be carried out at temperatures ranging from 20 to 100 C.
According to one embodiment, the reducing agent is added to the dyeing composition at the time of use.
According to another embodiment, the application of the dyeing composition may be followed by a short reducing step of 0.1 second to 30 minutes, such as from 0.1 second to 5 minutes, with a reducing agent of the thiol or borohydride type as described above.
According to another embodiment, the dyeing composition may comprise at least one oxidizing agent; the composition is then said to be “ready-to-use.”
In at least one embodiment, the composition is obtained by mixing the composition according to the disclosure with an oxidizing composition before application to the keratin materials to be treated.
The oxidizing agent may be any oxidizing agent conventionally used in the field. Thus, it may be chosen from hydrogen peroxide, urea peroxide, alkali metal bromates, per salts such as perborates and persulphates, and enzymes, among which mention may be made of peroxidases, oxidoreductases containing 2 electrons such as uricases, and oxygenases containing 4 electrons such as laccases. In at least one embodiment, the oxidizing agent is hydrogen peroxide.
The amount of oxidizing agent in the composition ranges from 1 to 40% by weight relative to the weight of the ready-to-use composition, such as from 1 to 20% by weight relative to the weight of the ready-to-use composition.
Generally, the oxidizing composition used is an aqueous composition and may be in the form of a solution or also an emulsion.
Customarily, the dyeing composition, free of oxidizing agent, is mixed with 0.5 to 10 equivalents by weight of the oxidizing composition.
It should be noted that the pH of the ready-to-use composition is, for example, from 4 to 12, such as from 7 to 11.5.
The application of the dyeing composition may be followed by an oxidizing post-treatment, or by a conditioning post-treatment optionally combined with an oxidizing post-treatment
Also disclosed herein is a multi-compartment device or dyeing “kit” in which a first compartment comprises a dyeing composition comprising at least one disulphide dye of formulae
