ABSTRACT:
The invention relates to the dyeing of keratin materials using dichromophore dyes with a carbonyl or heterocyclic linker. The invention relates to a dye composition comprising a dye with a carbonyl or heterocyclic linker, and to a dyeing process with a lightening effect on keratin materials, in particular keratin fibers, especially human keratin fibers such as the hair, using said composition, optionally in the presence of a cosmetically acceptable acid or base. It similarly relates to novel dyes and to the uses thereof in lightening keratin materials. This composition makes it possible to obtain a coloring with a lightening effect which is particularly resistant and visible on dark keratin fibers.
