The invention relates to compounds of formula ##STR1## in which X denotes a halogen atom, and R and R' denote a hydrogen atom, an alkyl, polyhydroxyalkyl, hydroxyalkoxyalkyl or alkoxyalkyl radical or an aminoalkyl radical optionally substituted on the nitrogen atom provided that at least one of the groups R and R' is a polyhydroxyalkyl, alkoxyalkyl or hydroxyalkoxyalkyl radical, and to dye compositions for keratinic fibres in which they are employed, to the preparation process and to intermediates.
该发明涉及以下式的化合物##STR1##其中X表示卤素原子,R和R'表示氢原子、烷基、多羟基烷基、羟基烷氧基烷基或烷氧基烷基基团或氨基烷基基团,该氨基烷基基团在氮原子上可选择性地取代,前提是R和R'中至少有一个是多羟基烷基、烷氧基烷基或羟基烷氧基烷基基团,以及它们在角蛋白纤维染料组合物中的使用、制备过程和中间体。
