The invention relates to 4-aminoindole derivatives of formula (I), and the addition salts thereof, mesomers thereof, isomers thereof and solvates thereof: and to their use for the oxidation dyeing of keratin fibres, and in particular of human keratin fibres such as the hair. The present invention makes it possible to achieve dark shades, natural shades and dark natural shades. The present invention also makes it possible to obtain powerful, chromatic, aesthetic, sparingly selective coloration of keratin fibres in varied shades, which is resistant to the various attacking factors to which the hair may be subjected. In particular, when the 4-aminoindole derivatives are combined with one or more heterocyclic oxidation bases, they make it possible to obtain a wide range of colours and coloration of keratin fibres that shows good chromaticity and good selectivity.
本发明涉及式(I)的
4-氨基吲哚衍
生物及其加成盐、共轭体、异构体和溶剂化物,以及它们在角蛋白纤维的氧化染色中的应用,特别是在人类角蛋白纤维,如头发的染色中。本发明使得可以获得深色、自然色和深自然色。本发明还使得可以获得强有力的、色彩艳丽的、美学的、节约选择性的角蛋白纤维染色,其颜色多样,且对头发可能遭受的各种攻击因素具有抵抗力。特别地,当将
4-氨基吲哚衍
生物与一种或多种杂环氧化碱结合时,它们使得可以获得广泛的颜色范围和良好的色度和选择性的角蛋白纤维染色。
