Monoazo compounds having a heterocyclic diazo component and an alkyl-3-(phenylamino)butyrate are useful as dyes for synthetic fibers such as cellulose acetate, cellulose triacetate, Nylon and especially polyester. The dyes of this invention have excellent fastness and dyeing properties by either heat fixation or exhaust, boil or pressure, methods of application. These novel compounds have the structure. ##STR1## wherein, for example, R is a heterocyclic component, R.sub.1 is hydrogen, lower alkyl, or lower alkoxy, R.sub.2 is lower alkyl, and R.sub.3 is hydrogen, lower alkyl, lower alkoxy, or lower alkanoylamino, and the various alkyl moieties may be substituted.
含有杂环重氮组分和烷基-3-(苯基氨基)丁酸酯的单偶氮化合物,可用作合成纤维(如醋酸纤维素、三醋酸纤维素、尼龙和特别是聚酯)的染料。本发明的染料具有优异的牢度和染色性能,可以通过热固定或耗尽、沸腾或压力等方法进行应用。这些新型化合物的结构为:##STR1## 其中,例如,R是杂环组分,R.sub.1是氢、较低烷基或较低烷氧基,R.sub.2是较低烷基,R.sub.3是氢、较低烷基、较低烷氧基或较低烷酰氨基,各种烷基基团可以被取代。
