The present invention is directed to a hair dyeing composition comprising a dissociative azo dye of the following general formula (I)
A-N=N-B (1)
wherein A represents a phenyl or naphthyl group, wherein these groups may be substituted, wherein these phenyl or naphthyl groups do not contain sulfo or carboxyl groups or quaternary ammonium groups; and B represents an aromatic group required for the compound represented by the general formula (I) to form a dissociative azo dye which is free from anionic sulfo or carboxyl groups and quaternary ammonium groups. Additionally, the present invention describes a method of dyeing human or animal hair by using such a dye and the use of this direct azo dye for dyeing human or animal hair. The use of this direct azo dye can impart the hair with an extremely vivid color and has a less color fade over the time.
本发明涉及一种染发组合物,该组合物包含以下通式 (I) 的离解型偶氮染料
A-N=N-B (1)
其中 A 代表苯基或萘基,这些基团可以被取代,其中这些苯基或萘基不含有硫基或羧基或季铵基;B 代表芳香基团,这些芳香基团是通式(I)所代表的化合物形成不含阴离子硫基或羧基及季铵基的离解型偶氮染料所必需的。此外,本发明还介绍了使用这种染料染人或动物毛发的方法,以及使用这种直接偶氮染料染人或动物毛发的方法。使用这种直接偶氮染料可以赋予头发极其鲜艳的颜色,并且随着时间的推移褪色较少。
