摘要

Product for the oxidative coloring of keratin fibers based on a combination substance developer-coupling, wherein the coupler contains at least one derivative [1, 1 '- biphenyl] -2, 4-diamine of formula ( I), or physiologically compatible salt thereof, wherein R1, R2, R3, R4, R5, same or different, represent, independently of one another, hydrogen, a halogen atom (fluorine, chlorine, bromine, iodine), a cyano group, a hydroxyl group, an alkoxy group (C1-C4), a hydroxy- (C1-C4) alkyl, (C1-C6), an alkyl (C1-C4) thioether group, a mercapto group, nitro, amino (NH2), an amino (C1-C4) monoalkylamino group, di (C1-C4) a trifluoromethane group, a -C (O) H, -C (O) CH3, -C (O) CF3, -Si (CH3) 3 a (C1-C4) hydroxyalkyl, dihydroxyalkyl (C2-C4), a -CH = CHR6 group, a - (CH2) p-CO2R7 or - (CH2) p-R8, where p = 1, 2 , 3 or 4, a -C (R9) = NR10 group or a C (R12) H-NR13R14, or two adjacent R1 groups R5 They form a bridge-O-CH2-O; R6 is hydrogen, a nitro group, a group CO2R7 or -C (O) CH3; R7, R9 and R12, identical or different, represent, independently, hydrogen or a group alkyl (C1-C4); R8 is an amino group or a nitrile group; R10, R13 and R14, identical or different, represent, independently of one another, hydrogen, a hydroxyl group, an alkyl group (C1-C4) alkyl, hydroxy (C1-C4), a (C2-C4) -hydroxyalkyl group or a group formula; R11 is hydrogen, an amino group or a hydroxyl group.
