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.
本文披露了适用于着色聚酰胺材料(尤其是尼龙地毯)的偶氮染料,这些染料是由氨基邻苯二酰亚胺和与硫代硫酸酯基取代的偶联剂制备而成。这些染料产生从黄色到蓝色的色调,还可以着色纤维素醋酸酯织物和羊毛。这些染料具有一般公式:其中R.sup.2和R.sup.4分别选自氢和多种有机取代基,偶联剂C为苯胺,1,2,3,4-四氢喹啉或苯基吗啉衍生物,其中Q-SSO.sub.3 M基附着在其氮原子上,Q为较低的烷基或类似的连接基,M为Na.sup. +、K.sup. +、NH.sub.4.sup. +或H.sup. +。这些染料在耐光、氮氧化物、洗涤、臭氧、升华、汗液和擦色等性能方面优越,并表现出良好的染色性,包括迁移、平整度、pH稳定性和染料固着性。
