More Information
Summary:Disclosed are disperse dyes comprising a cyanodinitroaniline azo moiety and a particular group of 2(2'-alkoxy-5'-acylamidoanilino)alkane couplers. These dyes give exceptional color depth and brightness, shade permanancy on heat setting, build, leveling, barre coverage, dye exhaustion and dyeing rate on polyester fiber over widely varying dyeing conditions of for example, temperature and pressure. The dyes exhibit blue shades with excellent colorfastness properties on polyester fibers and have excellent dyeability by heat fixation (Thermosol) or exhaust (boil and pressure) methods of application on this substrate. Uniform dyeability under a wide variety of conditions is an exceptional feature of the present dyes.
