Disclosed are azo dyes in which the diazo component is a diazotized 3-amino-2,1-benzisothiazole compound bearing one or two sulfo groups, and the coupler is either a 1,2,3,4-tetrahydroquinoline or a 2,3-dihydro-1,4-benzoxazine compound. These dyes exhibit excellent dyeing and fastness properties on polyamide fibers and also impart color to cellulose acetate fibers and wool. The dyes correspond to the general formula: <IMAGE> wherein R5 is 0-3 substituents independently selected from halogen, cyano, alkyl, alkoxy, sulfo, and the like; M is H+, Na+, K+ or the like; and C is the coupler which may be substituted with groups known to the art.
