    • 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; andZ.sub.2 represents a hydrogen atom or a C.sub.1 -C.sub.4 alkyl group;and its saltsis applied to said fibres, the colour being developed with the aid of an oxidizing system.
    • 用于染色角质纤维,特别是人角质纤维如毛发的方法,其特征在于,在适于染色的培养基中含有至少一个对应于下式的氨基吲哚的组合物(A):其中 R 1和R 3彼此独立地表示氢原子或C 1 -C 4烷基; R2表示氢或C1-C4烷基或COOR',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多羟基烷基; Z1表示氢或卤原子或C1-C4烷基或OR; R为氢原子或C 1 -C 4烷基; Z2表示氢原子或C1-C4烷基; 并且其盐被施加到所述纤维上,颜色借助氧化体系显影。
