Method for dyeing keratinous fibres, in particular human keratinous fibres, such as hair, characterized in that a composition (A) containing, in a medium appropriate for dyeing, at least one aminoindole corresponding to the formula: ##STR1## in which: R.sub.1 and R.sub.3, independently of one another, represent a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; R.sub.2 denotes hydrogen or a C.sub.1 -C.sub.4 alkyl group or COOR', R' being a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; R.sub.4 represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 hydroxyalkyl or C.sub.2 -C.sub.4 polyhydroxyalkyl group; Z.sub.1 represents a hydrogen or halogen atom or a C.sub.1 -C.sub.4 alkyl group or OR; R being a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; and Z.sub.2 represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group; and its salts is applied to said fibres, the colour being developed with the aid of an oxidizing system.
染发方法,特别是用于染人类角蛋白纤维,如头发,其特征在于使用一种含有在适宜染发介质中的至少一种氨基吲哚的组合物(A),该氨基吲哚符合以下通式:##STR1##其中:R1和R3各自独立地表示氢原子或C1-C4烷基;R2表示氢或C1-C4烷基或COOR',其中R'为氢原子或C1-C4烷基;R4表示氢原子或C1-C4烷基、C1-C4羟烷基或C2-C4多羟烷基;Z1表示氢或卤素原子或C1-C4烷基或OR,其中R为氢原子或C1-C4烷基;Z2表示氢原子或C1-C4烷基;及其盐,将其施用于所述纤维上,并通过氧化体系进行着色。
