  • Patent number: 7399319
    Abstract: Disclosed herein is a method for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising applying to the keratin fibers a dye composition comprising at least one compound chosen from styryl and imine compounds comprising a heterocycle that can undergo opening and/or dyes corresponding to these compounds whose heterocycles are open. The compositions and methods of the present disclosure may produce a coloration of keratin fibers that is chromatic and fast with respect to external factors such as shampooing, does not stain, and/or allows simultaneous dyeing and bleaching of keratin fibers.
