Compositions for the oxidation dyeing of keratin fibres, containing at least one oxidation base and at least one coupler chosen from indolizine derivative comprising at least one cationic group Z, Z being chosen from quaternized aliphatic chains, aliphatic chains comprising at least one quaternized saturated ring, and aliphatic chains comprising at least one quaternized unsaturated ring. Methods of using these cationic indolizine derivatives as couplers for the oxidation dyeing of keratin fibres, in combination with at least one oxidation base, and to dyeing processes using them. Some of these cationic indolizine derivatives are novel. |
