Use of 1,4-di(mono- or poly) hydroxyalkylamino-9,10-anthraquinones for dyeing human keratinous fibres.

摘要

The invention relates to the use of 1,4-bis[(mono- or polyhydroxyalkyl)amino]-9,10-anthraquinones: …… where R represents a C2 to C6 monohydroxyalkyl radical or a C3 to C6 polyhydroxyalkyl radical, for the dyeing of human keratinous fibres, to cosmetic dyeing compositions containing such anthraquinones, the dyeing compositions for keratinous fibres containing such anthraquinones in combination with nitro dyes of the benzene type, azo dyes, for direct dyeing, and/or with oxidation dyes for oxidation dyeing, and also to processes for dyeing keratinous fibres by direct dyeing or by oxidation dyeing.
