The present disclosure relates to a novel dye composition for the dyeing and/or lightening of keratin materials, such dye comprising a hemicyanin styryl chromophore thiol or disulfide dye of formula (I) or (II):
the organic or mineral acid salts thereof, optical isomers and geometric isomers thereof, and the solvates thereof such as hydrates. The present disclosure further relates to a dyeing process with a lightening effect on keratin materials, in particular keratin fibers, including human keratin fibers such as the hair, using said composition. This composition makes it possible to obtain a coloring with a lightening effect which is particularly resistant and visible on dark keratin fibers.
                            本公开涉及一种新型
染料组合物,用于染色和/或漂白角蛋白质材料,其中该
染料包括式(I)或(II)的半青素基
苯乙烯基色团
硫醇或二
硫醇
染料:其有机或矿物酸盐、其光学异构体和几何异构体,以及其溶剂化物,例如
水合物。本公开还涉及一种具有漂白效果的角蛋白质材料,特别是角蛋白纤维的染色工艺,包括人体角蛋白纤维,例如头发,使用该组合物。该组合物使得在深色角蛋白质纤维上获得特别耐用和明显的漂白效果。
