Abstract: A composition for dyeing keratin fibers, such as human keratin fibers, and further such as the hair, comprising at least one dye chosen from heteroylmethane type direct dyes, such as triheteroylmethane direct dyes and leuco precursors of such dyes, as defined herein. A method that uses the composition for dyeing keratin fibers, such as human keratin fibers, and further such as the hair, and a kit or device containing same.
Abstract: The present invention relates to the use, for dyeing keratin fibres, of at least one specific compound containing active methylene and of at least one compound chosen from an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative, which makes it possible to obtain, by reaction without an oxidizing agent, a coloration of the said keratin fibres.
Abstract: 1,3-Dihydroxybenzene derivatives of general formula (I) or (Ia) or physiologically tolerated, water-soluble salts thereof wherein R?1 denotes a substituted pyridyl group, a pyrimidyl group, a group of formula (IIa) or (IIIa) and the dyeing agents for keratin fibers containing these compounds.
Abstract: Compositions and method for coloring keratin fibers consisting of derivatives of benzo[b]furan-3-one and/or benzo-[b]-thiophen-3-one compounds with special reactive components. These compositions form intensely colored compounds when applied to keratin fibers. The compositions may also be used with substantive dyes and/or oxidation colorants.
