摘要:
WHEREIN R1 is hydrogen or an organic radical having a molecular weight of not more than 200; A is an aniline, 1,2,3,4tetrahydroquinoline or benzomorpholine disperse azo dye coupling component, and the 1,2-benzisothiazolon-1,1-dioxide group is bonded to the azo group at the 5- or 6-position; produce bright orange to red shades on polyester and cellulose acetate fibers and exhibit good to excellent dyeability and fastness properties.
Disperse azo dye compounds having the formula

摘要:
Mono- and dis-azo compounds particularly useful for dyeing polyamide textile materials in deep yellow to red crock-fast shades with excellent fastness to light and brightness and improved buildup and contain a phenyl or phenylazophenyl diazo component and an aniline coupling component, the nitrogen atom of which is substituted with an acylamidoethyl group camera ready copy.
