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.
