Patent number: 4593088
Abstract: Disclosed are new disperse azo dyes prepared from 2-amino-cinnamoylthiophene compounds. These dyes give bright blue shades, for example, on polyester, cellulose acetate and other synthetic fibers and exhibit improvements in one or more of such properties as bathochromic shift, fastness to light, sublimation, chlorine, heat, ozone, gas, perspiration, crock, and wash, build, pH stability, bloom resistance, depth of shade, leveling, strike rate, migration, and the like. The dyes have the general formula: ##STR1## wherein each R is a substituent selected for example from alkyl, substituted alkyl, hydroxy, alkoxy, halogen, nitro, alkoxycarbonyl, alkanoyloxy, alkanoyl, cyano, alkylamino, and dialkylamino, R.sup.14 is hydrogen or alkyl, C.sup.1 represents an aniline, tetrahydroquinoline or benzomorpholine coupling component which may be extensively substituted, and each of R.sup.12 and R.sup.13 is hydrogen or a substituent such as acyl, acylamido, alkyl, halogen, and cyano.
