Dyestuffs of the oxidizable developer-coupler type wherein the coupler is a 3,5-diamino-2-substituted-alkylbenzene of the formula ##STR1## wherein R.sub.1 is straight- or branched-chain alkyl of 1-8 carbon atoms, R.sub.2 is a straight- or branched-chain alkyl of 1-8 carbon atoms, phenyl, or phenyl substituted by alkyl of 1-4 carbon atoms or halogen atoms and the inorganic and organic salts thereof are very satisfactory for coloring hair. They are readily oxidized by atmospheric oxygen at room temperature without a catalyst, and they provide intense, bright and fast dyeings in a short tie. They are applied in conventional manner from an aqueous medium.
氧化性发展剂-偶联剂型染料,其中偶联剂为下式的3,5-二氨基-2-取代烷基苯:##STR1## 其中R.sub.1为1-8个碳原子的直链或支链烷基,R.sub.2为1-8个碳原子的直链或支链烷基,苯基或被1-4个碳原子的烷基或卤素原子取代的苯基,以及其无机和有机盐对于染发非常满意。它们在室温下无需催化剂就能被大气氧氧化,且能在短时间内提供强烈、明亮和持久的染色效果。它们可以从水介质中以传统方式应用。
