摘要
Oxidation hair dye compositions containing a 3-amino pyridine azo derivative of formula (I) as direct dye. Compositions for oxidation dyeing of keratinic fibers, particularly human hair, comprising, in a suitable medium, (i) at least one heterocyclic oxidation base, (ii) at least one 3-amino pyridine azo derivative of formula (I) as direct dye: B = a group of formula (Ia) or (Ib); R = 1-4 C alkyl; R1 = H, halogen such as Cl, Br or F, 1-4 C alkyl or 1-4 C alkoxy; R2 = H, 1-4 C alkyl or 1-4 C alkoxy; R4 = H, halogen such as Cl, Br or F, 1-4 C alkyl, nitro, amino or acyl(C1-C4)amino; R3 = H or R4 and R3 may together form an unsaturated 6-membered ring carrying an OH substituent which is chelated with one of the N atoms of azo group; A = -N(R5)(R6); R5 = H, 1-4 C alkyl, 1-4 C monohydroxyalkyl or 2-4 C polyhydroxyalkyl; R6 = H, 1-4 C alkyl, 1-4 C monohydroxyalkyl or 2-4 C polyhydroxyalkyl, phenyl ring or -CH2-SO3Na; X = monovalent or divalent anion such as Cl, Br, F, I, OH, bisulfate, or alkyl(C1-C6)sulfate such as (m)ethylsulfate; and (iii) at least one m-aminophenol derivative of formula (II) as coupler: R7 = H, 1-4 C alkyl, 1-4 C monohydroxyalkyl, 2-4 C polyhydroxyalkyl or 1-4 C monoaminoalkyl; R8 = H, 1-4 C alkyl, 1-4 C alkoxy or halogen selected from Cl, Br or F; R9 and R'9 (same or different) = H, halo, 1-4 C alkyl, 1-4 C alkoxy, 1-4 C monohydroxyalkyl, 2-4 C polyhydroxyalkyl, 1-4 C monohydroxyalkoxy or 2-4 C polyhydroxyalkoxy; with the proviso that at least one of R7, R8, R9 and R'9 is other than H.
