Disperse Dyes from 1, 2, 3, 4-Tetrachloroanthraquinone.

Disperse dyes were synthesized from 1, 2, 3, 4-tetrachloroanthraquinone. They showed good dyeing properties for Tetoron through high pressure dyeing treatment, although their properties for Acetate were not satisfactory. The dyes containing aryl group showed sun-fastness of 6 grade or above and sublimation-fastness of 4-5 grade. Even the dyes without aryl group showed improved fastness against sunlight, abrasion, washing, and sublimation over the corresponding 1, 4-disubstituted anthraquinones.
