There are described dyeing compositions for keratin fibres, and in particular for human hair, containing a dyestuff of the formula: ##STR1## in which A denotes an alkylene group, an alkylene group substituted by one or more OH groups, or an alkylene group interrupted by a hetero-atom such as oxygen or by an --NH-- group, R.sub.1 and R.sub.2, which are identical or different, denote hydrogen, alkyl, monohydroxyalkyl or polyhydroxyalkyl, or R.sub.1 and R.sub.2 can together form a heterocyclic ring chosen from among piperidino or morpholino groups, Y denotes alkoxy or NO.sub.2, R denotes hydrogen or lower alkyl, and if Y denotes alkoxy, Z denotes NO.sub.2 and is located in the para-position to the amine group, and if Y denotes NO.sub.2, (a) Z denotes alkoxy or OH and is located in the para-position to the NO.sub.2 group, or alternatively (b) Z denotes OH and is located in the para-position to the amine group, and also their cosmetically acceptable salts. Many of these dyestuff are novel.
描述了染色组合物,用于角蛋白纤维,特别是人类头发,含有以下式的染料:##STR1## 其中A表示烷基基团,一个或多个-OH基团取代的烷基基团,或者被氧原子或--NH--基团中断的烷基基团,R.sub.1和R.sub.2,相同或不同,表示氢,烷基,单羟基烷基或多羟基烷基,或者R.sub.1和R.sub.2可以共同形成从哌啶基团或吗啉基团中选择的杂环环,Y表示烷氧基或NO.sub.2,R表示氢或较低烷基,如果Y表示烷氧基,Z表示NO.sub.2,并且位于对位于胺基团,如果Y表示NO.sub.2,则(a)Z表示烷氧基或-OH并且位于对位于NO.sub.2基团,或者另外(b)Z表示-OH并且位于对位于胺基团,以及它们的化妆品可接受的盐。其中许多染料是新颖的。
