A process for dyeing keratinous fibers such as hair which comprises reacting the hair with a dyestuff of the general formula ##EQU1## where X is a chromophoric group, such as a group formed by coupling a phenylene diazonium salt with a diazo coupling compound, and where R has the formula --R'COOH, --R'COOCH.sub.3, --CH.sub.2 CH.sub.2 OH or --CH.sub.3 in which R' is an alkylene group containing 1,2 or 3 carbon atoms. The process gives good coloring of hair without damaging the condition. The invention also relates to novel dyes for use in the process and to processes for their production, and to dyeing compositions containing the dyes.
一种染色角蛋白纤维(如头发)的方法,包括将头发与一般公式为##EQU1##的染料反应,其中X是一个显色基团,例如通过偶联苯二氨盐与重氮偶联化合物形成的基团,而R具有以下公式--R'COOH,--R'COOCH.sub.3,--CH.sub.2 CH.sub.2 OH或--CH.sub.3,其中R'是含有1、2或3个碳原子的烷基基团。该方法使头发获得良好的染色效果而不损害头发的状况。该发明还涉及用于该方法的新型染料、其生产方法以及含有这些染料的染料组合物。
