  • Patent number: 7585332
    Abstract: The present invention relates to compositions for dyeing keratin fibers, and in particular human keratin fibers such as the hair, comprising at least one compound of styryl or imine type containing a heterocycle and at least one thiol compound. The present invention makes it possible in particular to obtain a chromatic and fast coloration of keratin fibers, especially with respect to shampooing. Moreover, the color obtained is visible even on dark hair without necessarily using an oxidizing composition. The invention also makes it possible to obtain a coloration which, under certain conditions, does not stain.
