Azo dyestuffs, insoluble in water, are represented by the formula: ##STR1## wherein A represents the residue of a diazotizable benzene component carrying at least two substituents or the residue of a diazotizable heterocyclic component, R represents alkyl, B represents an unsubstituted or substituted alkyl group, and X represents hydrogen, chlorine, bromine, acylamino, benzoylamino, alkoxycarbonylamino, phenoxycarbonylamino, alkylsulfonylamino or phenylsulfonylamino, the dyestuff molecule being free of groups causing water solubility by formation of ions. These dyestuffs can be used for dyeing of hydrophobic fibers, in particular polyester fibers. Affinity is excellent and there are obtained bright, full-bodied shades very fast to wet tests, sublimation, abrasion and light.
偶氮染料,不溶于水,其化学式表示为:##STR1## 其中A代表至少带有两个取代基的可重氮苯组分的残基或可重氮杂环组分的残基,R代表烷基,B代表未取代或取代的烷基基团,X代表氢、氯、溴、酰胺基、苯甲酰胺基、烷氧羰基胺、苯氧羰基胺、烷基磺酰胺基或苯基磺酰胺基,染料分子不含通过离子形成导致水溶性的基团。这些染料可以用于染色疏水性纤维,特别是涤纶纤维。亲和力极佳,可以获得明亮、饱满的色调,对湿测、升华、磨损和光线非常快。
