Indole-derived styryl dye comprising an alkylene linker, dye composition comprising this dye, process for lightening keratin materials using this dye

摘要

Indole compounds (I) and their organic or inorganic acid salts, optical isomers, geometrical isomers or solvates, which are hydrates, useful as fluorescent dye, are new. Indole compounds of formula (I) and their organic or inorganic acid salts, optical isomers, geometrical isomers or solvates, which are hydrates, useful as fluorescent dye, are new. Q ->anionic counter ion; W 1>(2-3C)-alkylene or (2-3C)-alkenylene (optionally substituted by one or more (1-4C)-alkyl or (1-4C)-aryl); n : 1 or 2 (preferred); m : 0 or 1; p : 0-4; Z 1>C or quaternized N; Z 2>-Z 4>N, CR 4>or N +>R 5>, where quaternized N or N +>R 5>cannot be present in the aromatic ring A; R 1>, R 4>halo, (di)(1-6C)(alkyl)amino, CN, OH, (poly)halo(1-6C)-alkyl, preferably CF 3, acyl(1-4C)(alkyl)amino, (1-6C)-alkoxy, (1-6C)-alkylthio, (poly)hydroxy(2-6C)alkoxy, (1-6C)alkoxycarbonyloxy, (1-6C)alkylcarbonylamino, (di)(1-4C)(alkyl)aminocarbonyl, (1-6C)alkylsulfonyl(1-4C)(alkyl)amino, (di)(1-4C)(alkyl)aminocarbonyl, (1-6C)alkylsulfonyl(1-4C)(alkyl)amino, (di)(1-4C)(alkyl)aminosulfonyl or (1-6C)alkyl (all optionally substituted by (1-6C)-alkoxy, OH or (di)(1-6C)(alkyl)amino); either R 2>R 1>; or 2R 2>+C (when p is greater than 2) : benzene ring; R 3>H, optionally substituted (1-6C)-alkyl, (di)(1-6C)(alkyl)amino, aryl or optionally substituted heterocycloalkyl; R 5>optionally substituted (1-6C)alkyl or aryl(1-6C)alkyl; L : a bond or bivalent 1-20C hydrocarbon (optionally substituted and interrupted by one or more divalent groups or their combinations, preferably N(R), N +>(R)(R1a), An ->, O, C(O) or S(O) 2); R, R1a : H, (1-4C)-alkyl, hydroxy(1-4C)alkyl, amino(1-4C)-alkyl or Het +>; Het +>optionally saturated heterocycle with 5-10 chains or heteroaryl with 5-10 chains; and An ->anionic counter ion. When: n is 2, then m is 0, and n is 1, then m is 1. Independent claims are included for: (1) a coloring composition comprising (I) in a suitable cosmetic medium; and (2) a process for coloring keratin materials comprising applying (I) on the materials.
