ABSTRACT:
Disclosed are azo dyes suitable for coloring polyamide material, particularly nylon carpet and which are prepared from aminophthalimides and couplers which are ##STR1## substituted with a thiosulfate ester group. These dyes produce yellow to blue shades and also color cellulose acetate fabrics and wool. The dyes have the general formula: ##STR2## wherein R.sup.2 and R.sup.4 are each selected from hydrogen and a large variety of organic substituents, the coupler C is an aniline, 1,2,3,4-tetrahydroquinoline, or benzomorpholine derivative wherein a Q-SSO.sub.3 M group is attached to the nitrogen thereof, Q being a lower alkylene or similar linking group, and M is Na.sup.+, K.sup.+, NH.sub.4.sup.+, or H.sup.+. The present dyes are superior in such properties as fastness to light, oxides of nitrogen, wash, ozone, sublimation, perspiration and crock, and exhibit good dyeability including migration, leveling, pH stability, and build.
