The present disclosure relates to polycationic monochromophoric hydrazone compounds of following formula (I):
wherein W
1
is a heteroaromatic radical comprising 5 or 6 ring members, optionally condensed with an aromatic ring comprising 6 ring members, comprising a quaternized nitrogen atom and optionally another heteroatom which may or may not be identical to nitrogen; X, which may or may not be identical, is a nitrogen atom or a CR
2
group; Z is a cationic group comprising at least one quaternized nitrogen atom.

The present invention concerns an auxochrome substituent for an oxidative dye coupler. The auxochrome substituent enables ready developer reaction with the coupler to form azomethine and leuco dyes. Manipulation of the auxochrome substituent enables a bathochromic or hypsochromic shift of the light absorbance by the azomethine dye formed with the auxochrome substituted coupler.
Composition comprising at least one mixed dye comprising at least two chromophores of (hetero) aromatic nitro or cyclic azine type, dyeing process, and mixed dyes
