B2

Process for coloring of human keratinous fibers comprises applying a tinctorial composition comprising a disulfide dye (L) or their salts and isomer solvates (hydrates) in a medium. Process for coloring of human keratinous fibers comprises applying a tinctorial composition comprising a disulfide dye (L) of formulae (I)-(IV) or their salts and isomer solvates (hydrates) in a medium. A, A 1a radical optionally containing a cationic chromophore; V1, V2 : bridging group; v, v1 : 0-1; X : 1-30C = hydrocarbon (optionally terminated at one or two ends by one or more divalent groups of -N(R)-, -N +>(R)(R)-, -O-, -S-, -CO- and/or -SO 2-); R : H, 1-4C alkyl, hydroxyalkyl, aminoalkyl, (hetero)cylcle (optionally aromatic); p : 0-1; C sat, C1 sat1-18C alkylene; and D : OH, hydroxyalkyl, alkoxy, carboxylic, carboxylate, amino or (di)alkylamino. Independent claims are included for: (1) a tinctorial composition comprising (L) in a medium; (2) a device with several compartments in which a first compartment contains a tinctorial composition and one second compartment contains a reducing agent able to reduce a disulfide bond; a disulfide cation dye (comprising a quarternary ammonium radical) of formulae (I)-(IV); and (3) disulfide dyes of formula (17) and (18). M : H, alkaline metal, ammonium (optionally substituted by one or more 1-18C alkyl (preferably 1-10C alkyl) (optionally substituted by OH)). [Image] [Image] [Image] [Image].
