Disclosed are mono azo dyes derived from diazotized 5-membered heterocyclic amines and certain aniline, 1,2,3,4-tetrahydroquinoline, and benzomorpholine couplers containing thiosulfate alkyl groups. These dyes are useful for dyeing synthetic fibers, cellulose acetate and wool, and particularly impart fast violet to blue shades on polyamide fibers, and in general, exhibit improved properties such as fastness to light, sublimation, ozone, oxides of nitrogen, perspiration, crock, and wash, and exhibit excellent build, pH stability, bloom resistance, depth of shade, leveling, migration, and the like. The dyes have the general formula: D--N.dbd.N--Coupler wherein D is a thiadiazol, isothiazol, pyrazol or thiophene type radical, and the Coupler is an aniline, tetrahydroquinoline, or benzomorpholine derivative wherein a --ZSSO.sub.3 M group is attached to the nitrogen thereof, the coupler ring may contain substituents such as alkyl, alkoxy, halogen, acylamido, alkylthio or aryloxy, the remaining hydrogen of the aniline coupler may be replaced by a substituent such as alkyl, substituted alkyl, alkenyl, aryl, or cycloalkyl, M is Na.sup.+, K.sup.+, NH.sub.4.sup.+ or H.sup.+, and Z is a linking group such as ethylene.
本发明涉及通过重氮化五元杂环胺和某些苯胺、1,2,3,4-四氢喹啉和苯基吗啡啶偶联剂制备的单偶氮染料,这些染料适用于染色合成纤维、醋酸纤维素和羊毛,特别是在聚酰胺纤维上呈现出快速紫色到蓝色的色调,并且通常具有改良的性能,如耐光、升华、臭氧、氮氧化物、汗水、脱色和洗涤的快速性,并且具有出色的建筑、pH稳定性、花期抗性、色深、平整、迁移等特点。该染料具有一般式:D-N.dbd.N-Coupler,其中D是一种噻二唑、异噻唑、吡唑或噻吩类型的基团,而Coupler是一种苯胺、四氢喹啉或苯基吗啡啶衍生物,其中一个-ZSSO.sub.3 M基团附加到其氮上,偶联剂环可以包含取代基,如烷基、烷氧基、卤素、酰胺基、烷硫基或芳氧基,苯胺偶联剂的其余氢原子可以被取代基所取代,例如烷基、取代烷基、烯基、芳基或环烷基,M是Na.sup. +,K.sup. +,NH.sub.4.sup.+或H.sup.+,Z是如乙烯等的连接基团。
