    摘要： This invention relates to azo dyes in which the diazotized amino component bears a sulfonic acid or salt group on its ring. These dyes have excellent dyeing properties on polyamide fibers, particularly nylon carpets and also impart color to cellulose acetate fibers and wool.The dyes correspond to the general formula: ##STR1## wherein R.sup.1 is selected from hydrogen and alkyl; M is H.sup.+, Na.sup.+, K.sup.+, Li.sup.+ or NH.sub.4.sup.+ ; and the coupler C is selected from a variety of couplers including anilines, tetrahydroquinolines, phenols , and the like which may be substituted with known substituents such as halogen, alkyl, alkoxy, acylamido, sulfamoyl, carbamoyl and the like.
