Composition comprising at least one mixed dye has at least one chromophore type methine and / or carbonyl, the coloration and mixed dyes

摘要

Dye composition (I), useful for dyeing human keratinous fibers comprises at least a mixed dye, comprising at least two different chromophores (methine and/or carbonyl compounds) bonded between the intermediates of linking bond(s) preventing the delocalization of the electrons of each of the chromophores. Dye composition (I) comprises at least a mixed dye, comprising at least two different chromophores (methine compounds and/or carbonyl compounds) secured between the intermediates of at least a linking bond terminating the delocalization of the electrons of each of the chromophores, where (I) does not comprise any mixed dye comprising two chromophores of the methines carrying a quinolinium group of formula (II). Independent claims are also included for: (1) coloring the hair (preferably humans) comprises applying (I) to the hair optionally in the presence of an oxidizing agent for sufficient time to obtain color, rinsing and washing the hair; and (2) a device comprising several compartments in which (I) is present in at least one compartment.
