2,4-Dichloro-3-alkylidene-aminophenols having the formula: ##STR1## wherein R.sub.1 represents hydrogen or an alkyl radical having 1 to 6 carbon atoms and R.sub.2 represents an alkyl radical having 1 to 6 carbon atoms or an aryl radical, with the proviso that R.sub.2 can only be an aryl radical when R.sub.1 is hydrogen. The 2,4-dichloro-alkylidene-aminophenols can be produced by reaction of 2,4-dichloro-3-aminophenol with the corresponding aldehydes or ketones. They are suitable as such, or in the form of their salts with inorganic or organic acids, as coupler components in oxidation hair dyes.
具有以下公式的2,4-二氯-3-烷基亚胺基酚:##STR1## 其中R.sub.1代表氢或具有1至6个碳原子的烷基基团,而R.sub.2代表具有1至6个碳原子的烷基基团或芳基基团,但前提是当R.sub.1为氢时,R.sub.2只能是芳基基团。2,4-二氯-烷基亚胺基酚可以通过2,4-二氯-3-氨基酚与相应的醛或酮反应制备而成。它们适用于氧化染发剂中的偶合剂成分,可以作为其盐的形式与无机或有机酸一起使用。
