Disclosed are azo compounds having the formula ##STR1## in which R.sup.4 is straight or branched lower alkylene, Z is 1-3 groups selected from such heteroatom groups as --OH, lower alkanoyloxy, lower alkoxy, lower alkoxycarbonyl, lower alkoxyalkoxy, mono- or dialkylamino, --CN, carbamoyl, formamide, lower alkyl substituted carbamoyl, lower alkoxycarbonylamino, lower alkanoylamino, hydroxy substituted lower alkoxy, halogen, lower alkylthio, lower alkylsulfonyl, and various heterocyclic groups such as furyl and pyrrolidono, R is selected from straight or branched lower alkyl, phenyl and phenyl substituted with straight or branched lower alkyl, halogen, or straight or branched lower alkoxy, R.sup.2 is hydrogen or lower alkyl, and A is an aniline, tetrahydroquinoline, or benzomorpholine coupler component which may be substituted with a wide variety of groups. These azo compounds produce red to blue shades on polyamide, polyester and cellulose acetate fibers and exhibit markedly improved properties such as fastness and dyeability, particularly on synthetic polyamide fibers.
揭示了具有以下式的偶氮化合物##STR1##其中R.sup.4是直链或支链低碳烷基,Z是1-3个从--OH、低脂肪酰氧基、低烷氧基、低烷氧羰基、低烷氧基氧基、单或二烷基氨基、--CN、氨基甲酰、甲酰胺、低烷基取代的甲酰胺、低烷氧羰胺基、低脂肪酰胺基、羟基取代的低烷氧基、卤素、低烷硫基、低烷基磺酰基以及各种杂环基团(如呋喃基和吡咯烷基),R选自直链或支链低烷基、苯基和苯基取代的直链或支链低烷基、卤素或直链或支链低烷氧基,R.sup.2是氢或低烷基,A是苯胺、四氢喹啉或苯基吗啉偶联组分,可以用各种基团取代。这些偶氮化合物在聚酰胺、聚酯和醋酸纤维上产生红色到蓝色的色调,并表现出明显改善的性能,如牢度和染色性,特别是对合成聚酰胺纤维。
