The invention relates to a process for dyeing keratin fibers, comprising the use of one or more metal catalysts and of a composition (A) comprising: —one or more oxidizing agents, and —at least one monoaminobenzene of formula (I), or an addition salt or solvate thereof in which the radicals R1 to R5 represent, independently of each other: a hydrogen atom; a halogen atom, a C1-C6 alkyl radical, a C1-C6 alkoxy radical, a carboxylic radical (—COOH), a sulfonic radical (—S03 H); two of the adjacent radicals R1 to R5 possibly forming, with the carbon atoms that bear them, a saturated or unsaturated 5- to 7-membered ring, optionally comprising from 1 to 2 heteroatoms, preferably oxygen, the said ring being optionally fused with a saturated or unsaturated 5- to 6-membered ring; on condition that at least one of the radicals R1 to R5 represents an optionally substituted alkoxy radical and preferably at least one of the other radicals R1 to R5 is a hydrogen atom.
本发明涉及一种角蛋白纤维染色工艺,包括使用一种或多种金属催化剂和一种组合物(A),组合物(A)包括: -一种或多种氧化剂,和 -至少一种式(I)的单胺苯,或其加成盐或溶液,其中自由基 R1 至 R5 各自代表:氢原子、卤素原子、C1-C6 烷基、C1-C6 烷氧基、羧基 (-COOH)、磺酸基 (-S03 H);R1 至 R5 中相邻的两个基团可与含有它们的碳原子形成饱和或不饱和的 5 至 7 元环,可选择包含 1 至 2 个杂原子,最好是氧,所述环可选择与饱和或不饱和的 5 至 6 元环融合;条件是 R1 至 R5 自由基中至少有一个代表任选取代的烷氧基,且 R1 至 R5 自由基中至少有一个是氢原子。
