摘要

Agent for coloring fibers containing keratin, especially human hair, containing a combination consisting of components (A) at least one derivative formylated quinolinium of formula I and derivatives thereof (see formula) wherein R1 means alkyl group (with 1 to 6 carbon atoms), an alkyl aryl-alkenyl group (containing 2 to 6 carbon atoms), an aryl group, a group (with 1 to 6 carbon atoms) or a heteroarylalkyl group (with 1 to 6 carbon atoms), R2 and R3 are each, independently of one another, a hydrogen atom, a halogen atom, an alkyl group (with 1 to 6 carbon atoms), an alkoxy group (with 1 to 6 carbon atoms), a hydroxy-alkoxy group (with 1 to 6 carbon atoms), a hydroxy group, a nitro group, an aryl group, a trifluoromethyl group, an amino group which may be substituted by alkyl groups (with 1 to 6 carbon atoms) or mean acyl groups (with 1 to 6 carbon atoms carbon), A- means a physiologically compatible anion or N-oxide of quinoline, (B1) 2-amino-6-chloro-4-nitrophenol or its physiologically compatible salt with an organic or inorganic acid and (B2) at least an aromatic, primary or secondary, different from (B1) or physiologically compatible salt thereof with an organic or inorganic acid amine.
