Disclosed are mono azo dyes derived from diazotized 5-membered heterocyclic amines and certain aniline, 1,2,3,4-tetrahydroquinoline, and benzomorpholine couplers containing sulfoalkyl groups. These dyes impart fast violet to blue shades on polyamide fibers and 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 --Z--SO.sub.3 M group is attached to the nitrogen thereof, the coupler ring may contain one or more substituents selected from lower alkyl, lower alkoxy, halogen, acylamido, alkylthio or aryloxy, the remaining hydrogen of the aniline coupler may be replaced by a substituent such as lower alkyl, substituted lower alkyl, lower 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.
