Abstract:
The present invention relates to a composition for dyeing keratin fibers, comprising (a) at least one direct dye; and (b) at least one specific pyran-based compound. The composition according to the present invention may further include (c) at least one specific sulfone compound. The composition according to the present invention is a one-part composition and can prevent or reduce skin staining by the direct dye on the skin such as the scalp, while providing the keratin fibers with good cosmetic effects such as good coloring properties.

Claim (Index 33):
A method for dyeing keratin fibers, comprising applying to the keratin fibers a composition, the composition comprising:\n (a) at least one direct dye; and (b) at least one pyran-based compound chosen from compounds according to formula (A) or (B) below: wherein: R 1  and R 2 , independently from each other, are chosen from a hydrogen; an optionally substituted, linear or branched C 1-18  alkyl group; an optionally substituted, C 3-18  alicyclic alkyl group; an optionally substituted, linear or branched C 2-18  alkenyl group; an optionally substituted, linear or branched C 2-18  alkynyl group; an optionally substituted C 6-18  aryl group; an optionally substituted C 7-18  aralkyl group; an optionally substituted, linear or branched C 1-18  alkoxyl group; or an optionally substituted, linear or branched C 2-18  acyl group, and R 3  is chosen from an optionally substituted, linear or branched C 1-18  alkyl-COO\u2014; an optionally substituted, linear or branched C 2-18  alkenyl \u2014COO\u2014; an optionally substituted, linear or branched C 1-15  alkyl-CO\u2014; or an optionally substituted, linear or branched C 2-18  alkenyl \u2014CO\u2014.
