Composition for dyeing human keratinic fibers, especially hair, comprises a conjugate consisting of two dye molecules linked by a hydrocarbon group with at least one nitrogen atom and at least two cationic charges
Composition for dyeing human keratinic fibers comprises a conjugate (I) consisting of two azo, methine, azomethine, phenothiazine, triarylmethane, xanthene, phenanthridine or phthalocyanine dye molecules linked by a hydrocarbon group containing at least one nitrogen atom and having at least two cationic charges. Composition for dyeing human keratinic fibers comprises a conjugate of formula (I). D-Z-D (I) D = an azo, methine, azomethine, phenothiazine, triarylmethane, xanthene, phenanthridine or phthalocyanine dye; and Z = a 1-20C hydrocarbon group containing at least one nitrogen atom and having at least two cationic charges. Independent claims are also included for: (1) direct dyeing of human keratinic fibers by applying at least one of the compositions; (2) oxidation dyeing of human keratinic fibers by applying at least one of the compositions, which also contains at least one developer and optionally at least one coupler, in the presence of an oxidizing agent; (3) kit comprising the composition in one compartment and an oxidizing composition in another compartment.
