摘要

Tetrahydropyrrolo/pyrido[1,2-a]indolinium thiol/sulfur compounds (I) and their organic or inorganic acid salts, optical isomers, geometrical isomers, solvates or hydrates, useful as fluorescent dye, are new. Tetrahydropyrrolo/pyrido[1,2-a]indolinium thiol/sulfur compounds of formula (I) and their organic or inorganic acid salts, optical isomers, geometrical isomers, solvates or hydrates, useful as fluorescent dye, are new. R 1halo, 1-6C alkyl (optionally substituted), 1-6C alkoxy, 1-6C alkylthio, (di)(1-6C alkyl)amino, (1-6C)poly-haloalkyl, OH, (1-6C) polyhydroxyalkyl, polyhydroxy(1-6C)alkoxy, NO 2, CN, R-G-C(G1a)-, R-C(G1a)-G-, R1aS(O) 2-N(R)- or RR1aN-S(O) 2-; G, G1a : O, S or NR1a; R, R1a : H or 1-6C alkyl; R 2, R 31-6C alkyl; B 1heteroaryl (both optionally substituted); L : bivalent 1-20C hydrocarbon chain (optionally substituted, interrupted and/or terminated in one or other of its ends by one or more divalent group of -N(R1aa)-, -N +(R1aa)(R1bb)-, An -, -O-, -S-, -C(O)- or -S(O) 2-, or Het +); Het +5-10 membered heterocyclic ring (optionally saturated) or 5-10 membered heteroaryl ring; R1aa, R1bb : H, 1-6C alkyl, hydroxy(1-6C)alkyl or (di)(1-6C alkyl)amino(1-6C alkyl); An -anionic counter ion; Y 1H, alkaline metal, alkaline earth metal, ammonium group of formula N +Ralpha Rbeta Rgamma Rdelta , phosphonium group of formula P +Ralpha Rbeta Rgamma Rdelta or thiol protecting group; m : 0 (preferred) or 1; n : 1 or 2 (preferred); p : 0-4; q : 1-3; and Ralpha , Rbeta , Rgamma , Rdelta : H or 1-4C alkyl. Provided that: when n is 2, then m is 0; when n is 1, then m is 1; when p is 2-4, R 1is same or different; and -LS-(Y 1) mis linked to the chromophore derivative of tetrahydropyrido[1,2-a]-indolinium compounds (I). Independent claims are included for: (1) a coloring composition comprising at least one fluorescent dyes (I) in cosmetic medium. (2) a method of coloring keratin materials, comprising applying the composition on the keratin fibers; and (3) a multi-compartment device comprising a first compartment containing the coloring composition; and a second compartment containing a reducing agent.
