ABSTRACT:
This invention relates to azo dyes in which the diazotized amino component bears 1 or 2 sulfated hydroxyalkoxycarbonyl or N-(hydroxyalkyl)carbamoyl groups on its ring. These dyes have 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: ##STR1## wherein R.sup.1 represents up to three of a large variety of groups such as alkyl, alkoxy, acyl, arylthio, and the like; X' is O, NH, N(alkyl)- or N(aryl)-; Z is selected from straight- or branched-chain alkylene which may be substituted, for example, with phenyl, halogen, OSO.sub.3 M, alkoxy, aryloxy and the like; M is H, Na, K or NH.sub.4 ; n is 1 or 2; and the coupler C is selected from a variety of couplers including anilines, tetrahydroquinolines, phenols and the like.
