摘要

Dye composition comprises a cationic hydrazone dye (I) and a thickening polymer and/or surfactant in a medium suitable for dyeing human keratinic fibers. Dye composition comprises a cationic hydrazone dye of formula (I) and a thickening polymer and/or surfactant in a medium suitable for dyeing human keratinic fibers. [A-C(R 3)=N-N(R 1)-B] +>X (I) R 1, R 3H, 1-10C alkyl or 1-10C hydroxyalkyl; A : an optionally substituted C-bonded pyrimidinone, indole or benzothiazole group; B : an optionally substituted C-bonded dibenzofuran, carbazole, anthraquinone or dibenzothiophene group; X : an anion. An independent claim is also included for a kit comprising a composition as above in one compartment and an oxidizing composition in another compartment.
