| abstract | The present invention relates to agents for dyeing keratin fibers, in particular human hair, which contain at least one p-aminophenol derivative in a suitable medium for dyeing andn(A) at least one compound of formula (I) or one of its physiologically acceptable salts as a coupler componentnwherein R 1 and R 2 are independently hydrogen, trifluoroacetyl, C 1-4 alkyl, C 1-4 monohydroxyalkyl, C 2-4 polyhydroxyalkyl or C 1-4 aminoalkyl,nR 3, R 4 and R 5 independently of one another represent hydrogen, a C 1-4 -alkyl group, a C 1-4 -alkoxy group or a halogen atom, in particular a chlorine atom, where at least one of the radicals R 3, R 4 and R 5 represents a halogen atom or a C 1-4 alkoxy group, and / orn(B) at least one compound of formula (II) or one of its physiologically acceptable salts as a coupler componentnwhere R 6 and R 7 independently of one another represent hydrogen or a C 1-4 -alkyl group,nR 8 and R 9 independently represent hydrogen, an amino group, a hydroxy group or a C 1-4 alkoxy group, andnZ is hydrogen or a halogen atom, in particular a chlorine atom, wherein at least one of the radicals R 6, R 7, R 9 or Z is different from hydrogen, with the proviso that when the compound of the formula (I) 3-amino-2- Chloro-6-methylphenol, then at least one other coupler component is included. With the aid of the compositions according to the invention, it is possible to achieve expressive, brilliant shades which, even in toxicological terms, represent an advance over the prior art. |
