Dyestuffs of the oxidizable developer-coupler type wherein the developer is a novel 4,7-diaminoindazole of the formula: ##STR1## wherein one of the R's represents C.sub.1-4 alkyl and the other R represents a substitutent selected from the group consisting of C.sub.1-4 alkyl and H (and the water-soluble 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 time. They are applied in conventional manner from aqueous medium.
氧化性显色剂-显色剂类型的染料,其中开发剂是一种新型的4,7-二氨基吲哚,其化学式为:##STR1## 其中一个R代表C.sub.1-4烷基,另一个R代表从C.sub.1-4烷基和H组成的基团中选择的取代基(及其水溶性盐)非常适合用于染发。它们在室温下可以在无需催化剂的情况下被大气氧氧化,且在短时间内提供强烈、明亮和持久的染色效果。它们以传统方式从水性介质中应用。
