, (2008/06/13)
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 R2 and R4 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-SSO3 M group is attached to the nitrogen thereof, Q being a lower alkylene or similar linking group, and M is Na+, K+, NH4+, or H+. 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.

Monoazo compounds containing a phthalimidyl diazo component the aromatic ring of which can be substituted with one or two substituents, and the nitrogen of which may be substituted, and a 1,2,3,4-tetrahydroquinoline disperse azo dye coupling component which contains at least one alkyl substituent, are useful for dyeing cellulose acetate, nylon, and especially polyester fibers on which the compounds exhibit good fastness and dyeability properties.
