  • Patent number: 8034125
    Abstract: The present invention relates to the dyeing of keratin materials using two colorless dye precursors, at least one of which contains a disulfide/thiol unit, said precursors reacting together chemically to form the color in situ. The process according to the invention makes it possible in the context of certain variants to solve the problems caused by the color generated during the process, while at the same time not degrading the efficacy of the coloration, and especially of the lightening effect. The colorations obtained are moreover powerful, chromatic, sparingly selective, and fast with respect to external agents such as sunlight, perspiration and especially shampoo.
