DISPERSE DYES FROM 2-HALO-4,6-DINITROANILINE AND SELECTED 2(2'-ALKOXY-5'-ALKANOYLAMINOANILINO)ALKANES Abstract of the Disclosure Disclosed are disperse dyes comprising a chloro- or bromodinitro- aniline azo moiety and a particular group of 2(2'-alkoxy-5'-alkanoyl- aminoanilino)alkane couplers. These dyes give exceptional color depth and brightness, shade permanency on heat setting, build, leveling, barr? coverage, dye exhaustion and dyeing rate on fibers of polyester, cellulose acetate, cellulose triacetate, and polyamide (nylon) 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. - 1 -
