Abstract:
A composition for the oxidation dyeing of keratin fibers, said composition comprising, in a medium which is suitable for dyeing:a) at least two oxidation bases which are different from each other,b) at least one indole coupler chosen from compounds of formula (I) and acid addition salts thereof: ##STR7## in which: R.sub.1 is chosen from a hydrogen atom and C.sub.1 -C.sub.4 alkyl radicals,R.sub.2 and R.sub.3, which may be identical or different, are chosen from a hydrogen atom, C.sub.1 -C.sub.4 alkyl radicals, carboxyl radicals and (C.sub.1 -C.sub.4)alkoxycarbonyl radicals,X is chosen from a hydrogen atom, halogen atoms, C.sub.1 -C.sub.4 alkyl radicals, C.sub.1 -C.sub.18 alkoxy radicals, and acetylamino radicals,wherein said at least two oxidation bases and said at least one indole coupler are present in said composition in a combined amount effective for the oxidation dyeing of keratin fibers.
