Zusammenfassung: | In an oxidation color for keratin fibers, especially human hair, which contains p-aminophenol derivative(s) in a suitable medium, the coupler component comprises 3-aminophenol(s) (I) and/or 2-aminopyridine(s) (II) and/or their physiologically compatible salts, provided that, if (I) is 3-amino-2-chloro-6-methylphenol, the color also contains other coupler(s). In an oxidation color for keratin fibers, especially human hair, which contains p-aminophenol derivative(s) in a suitable medium, the coupler component comprises 3-aminophenol(s) of formula (I) and/or 2-aminopyridine(s) of formula (II) and/or their physiologically compatible salts, provided that, if (I) is 3-amino-2-chloro-6-methylphenol, the color also contains other coupler(s): [Image] R 1>, R 2>H, trifluoroacetyl, 1-4C alkyl, 1-4C monohydroxyalkyl, 2-4C polyhydroxyalkyl or 1-4C aminoalkyl; R 3>-R 5>halogen, especially chlorine or 1-4 C alkoxy in at least one case, otherwise H or 1-4 C alkyl; R 6>, R 7>H or 1-4 C alkyl; R 8>, R 9>H, amino, hydroxy or 1-4 C alkoxy; Z : H or halogen, especially Cl; at least one of R 6>, R 7>, R 8> and Z not : H. |
