Abstract:
A method for coloring keratin containing fibers which comprises: applying to the keratin containing fibers a composition comprising:A) at least one of onium aldehydes and onium ketones of the formula I and derivatives thereof: â€ƒin which R1 is a hydrogen atom, a (C1-4) alkyl group, an aryl group or a heteroaryl group, R2, R3 and R4 independently of one another represent a hydrogen atom, a halogen atom, a (C1-4) alkyl group, a (C1-4) alkoxy group, hydroxy-(C1-4)-alkoxy group, hydroxy group, nitro group, aryl group, trifluoromethyl group, amino group which may be substituted by (C1-4) alkyl groups or a (C1-4) acyl group; two of the substituents together may also form a fused benzene ring, R5 is a (C1-4) alkyl group, aryl group, aralkyl group or heteroaryl group, X is a direct bond or a vinylene or phenylene group which may be substituted and Y is halide, benzenesulfonate, p-toluene sulfonate, methane sulfonate, trifluoromethane sulfonate, perchlorate, sulfate, hydrogen sulfate or tetrachlorozincate or the N-oxide of the heterocycle; in combination with B) at least one compound selected from the group consisting of primary aliphatic amines, secondary aliphatic amines, aromatic amines, nitrogen-containing heterocyclic compounds, &agr;- to &ohgr;-amino acids, oligopeptides comprising 2 to 9 amino acids, aromatic hydroxy compounds and CH-active compounds; the reaction product of A) with B) can also be present.
