Disclosed herein is a mixed cationic direct dye comprising at least one anthraquinone chromophore and at least one cationic chromophore chosen from cationic azo chromophores and cationic hydrazone chromophores, wherein the at least one anthraquinone chromophore is bound to the at least one cationic chromophore by means of at least one linkage. Also disclosed herein is a dyeing composition comprising at least one mixed cationic direct dye. Further disclosed herein is a method of dyeing of keratin fibers, for example, keratin fibers, comprising applying said dyeing composition to the keratin fibers. Still further disclosed herein is a multi-compartment kit comprising at least one compartment comprising at least one dye composition and at least one second compartment comprising at least one oxidizing agen't.
A mixed cationic direct dye comprising at least one anthraquinone chromophore and at least one cationic chromophore chosen from cationic azo chromophores and cationic hydrazone chromophores, wherein the at least one anthraquinone chromophore is bound to the at least one cationic chromophore by means of at least one linkage.
A dyeing composition comprising, in a medium suitable for the dyeing of keratin fibers, at least one mixed dye comprising at least one anthraquinone chromophore and at least one cationic chromophore chosen from cationic azo chromophores and cationic hydrazone chromophores, wherein the at least one anthraquinone chromophore is bound to the at least one cationic chromophore by means of at least one linkage.
A method of dyeing of keratin fibers, comprising:
A multi-compartment kit comprising at least one first compartment contains at least one dyeing composition comprising at least one mixed dye, and optionally at least one additional direct dye different from the at least one mixed dye, optionally at least one oxidation base, optionally at least one coupling agent, and at lesat one second compartment containing at least one oxidizing agent,
