摘要

Composition for dyeing keratin-containing fibers, especially human hair, which comprises a combination of components (A) at least one derivative formylated quinolinium according to formula I and derivatives thereof (see formula) wherein R 1 is an alkyl group (C1-C6), alkenyl group (C2-C6), aryl group, aryl-alkyl (C1-C6) alkyl or heteroaryl group-alkyl (C1-C6) R 2 and R 3, independently of one another they are each a hydrogen atom, a halogen atom, an alkyl group (C1-C6), alkoxy group (C1-C6) group, a hydroxy-alkoxy (C1-C6), a hydroxy group, nitro group, aryl group, trifluoromethyl group, amino group which may be substituted by alkyl groups (C1-C6) acyl group or (C1-C6), A- is a physiologically compatible anion or N oxide quinoline, (B1) at least one amino-substituted derivative of pyrimidine or a physiologically acceptable salt thereof with an organic or inorganic acid acu erdo formula II (See formula) wherein R 1, R 2 and R 3 independently of one another are a hydroxyl group, a (C1-C6) -alkoxy or an amino group, and R 4 is a hydroxyl group or group -NR 5 R 6 wherein R 5 and R 6, independently of one another, are a hydrogen atom, -alkyl (C1-C6) -hydroxyalkyl group one (C1-C6), provided that at most two of R 1, R 2, R 3 and R 4 groups are a hydroxyl group, and (B2) at least one aromatic primary or different secondary (B1) amine, or a physiologically acceptable salt with a organic or inorganic acid.
