Abstract

Dyes are made by sulphonating the product obtained by heating one molecular proportion of 2,3-dichloro-1,4-diamino-anthraquinone with two molecular proportions of an alkali metal phenoxide carrying in p-position a phenyl group attached either directly or through an oxygen atom, or with two molecular proportions of an alkali metal salt of 2-hydroxydiphenylene oxide. The products dye wool violet shades. In examples, 2,3 - dichloro - 1,4 - diaminoanthraquinone is heated with the potassium salts of (1) 4-hydroxydiphenyl, (2) 4-hydroxydiphenyl ether, (3) 2-hydroxydiphenylene oxide, followed by sulphonation. Specification 26944/11, [Class 2 (iii)], is referred to.
