<p>Coloring human keratin fibers, comprises applying, to the fibers, a dye composition comprising at least one dye comprising disulfide structures (I)-(IV) and dyes having disulfide structures (V) and (VI) and their salts, isomers or solvates such as hydrates, in a medium. Coloring human keratin fibers, comprises applying, to the fibers, a dye composition comprising at least one dye comprising disulfide (A) structures of formula (A-X p-C sat-S-S-C sat-X p-A) (I), (II), (III) or (A-X p-C sat-S-S-C sat-X p-D) (IV) and dyes having disulfide structures (B) of formula (V) and (VI) and their salts, isomers or solvates such as hydrates, in a medium. A, A1a : W1-N=N-Ar1-; W1 : pyridinium, benzimidazolium, pyrazolium, benzothiazolium, optionally substituted by one or more 1-4C alkyl; Ar1 : 5C or 6C aryl, or aromatic bicycle comprising naphthyl, optionally substituted by one or more halo (preferably chlorine or fluorine), 1-4C alkyl (preferred), hydroxyl groups, alkoxy groups, hydroxyalkyl groups, or amino or (di)alkylamino; V1, V1a : a bridging group; v, v1 : 0 or 1; X : linear or branched 1-30C hydrocarbon chain (optionally saturated, optionally interrupted and/or optionally terminated at one or both of its ends by one or more divalent groups comprising -N(R)-, -N +>(R)(R)-, -O-, -S-, -CO-, -SO 2- and/or aromatic or non aromatic (hetero)cyclic group, optionally saturated, optionally fused and optionally including one or more heteroatoms, optionally substituted); R : H, 1-4C alkyl, hydroxyalkyl or aminoalkyl; p : 0 or 1; C sat, C1 sat1-18C alkylene chain optionally substituted and cyclic; D : group comprising OH, hydroxyalkyl, alkoxy, carboxyl, carboxylate, amino, alkylamino or dialkylamino; and M1a : an organic or mineral acid salt. Independent claims are included for: (1) the dye composition comprising (I)-(IV) in a medium; and (2) the disulfide dyes (I)-(IV). [Image].</p> |
