ABSTRACT:
The present invention relates to a dye composition comprising at least one oxidation base and at least one coupler of the 2,3,5-triaminopyridine type. This composition may be useful for dyeing keratin fibers, such as the hair. Also disclosed are a process for dyeing keratin fibers and a multi-compartment dyeing kit using the claimed dye composition.Such a composition can make it possible to obtain strong, uniform dyeing results between the end and the root, which are resistant to external agents, while at the same time being capable of giving varied shades, for example, in fundamental shades such as chestnut, grey or black shades.
