Disperse dyes, 6-phenoxy-1, 4-disubstituted anthraquinones and 6, 7-diphenoxy-1, 4-disubstituted anthraquinones were prepared and their dyeing properties on acetate and Tetoron examined. The colors of dyed cloth varied from violet to blue. Their dyeabilities on Tetoron were good; particularly, 6-phenoxy-1, 4-disubstituted anthraquinones sho-wed excellent affinities to Tetoron in high temperature dyeing treatment. Their dyeabilities on acetate, however, were not satisfactory. The λ<SUB>max </SUB> of 6, 7-diphenoxy-1, 4-disubstituted anthraquinones in ethyl alcohol shifts toward longer wavelength than that of the corresponding 1, 4-disubstituted anthraquinones. Their light-fastness on acetate was good, and their abrasion-as well as wash-fastness was excellent. They, particularly 6, 7-diphenoxy-1, 4-disu-bstituted anthraquinones, showed good sublimation-fastness.
