The invention relates to new cationic azo dyestuffs which correspond to the general formula: ##STR1## in which R.sub.1 represents an alkyl radical or a substituted alkyl radical, R.sub.2 represents a hydrogen atom, an alkyl radical or a substituted alkyl radical, R.sub.3 represents a cyano, carbamoyl or carbalkoxy radical, R.sub.4 represents a hydrogen or halogen atom or an alkyl or alkoxy radical, D.sup..sym. represents a cycloammonium radical and A.sup..crclbar. represents an anion. These dyestuffs are very suitable for dyeing and printing textile materials based on polymers or copolymers of unsaturated nitriles or on acid-modified polyesters or polyamides, in shades very fast to light and wet treatments.
本发明涉及新的阳离子偶氮染料,其符合以下一般式:##STR1## 其中,R.sub.1代表烷基基团或取代烷基基团,R.sub.2代表氢原子、烷基基团或取代烷基基团,R.sub.3代表氰基、氨基甲酰基或羰基烷氧基基团,R.sub.4代表氢原子或卤素原子或烷基或烷氧基基团,D.sup..sym.代表环氨基基团,A.sup..crclbar.代表阴离子。这些染料非常适合用于染色和印刷基于不饱和腈的聚合物或共聚物或酸改性的聚酯或聚酰胺的纺织材料,颜色非常耐光和耐湿处理。
