Abstract
The invention comprises dyes of the formula <FORM:1010999/C4-C5/1> wherein Y is H or SO3M, R is H, methyl, ethyl, methoxy or ethoxy and M is H, a metal, ammonium or amine cation. The dyes are made by reacting 1-amino-4-bromo- or -chloro-anthraquinone-2-sulphonic acid with an aminobenzyl sulphone of the formula <FORM:1010999/C4-C5/2> and then if desired sulphating the -OH group in the product, or by reacting the anthraquinone compound with the sulphate ester of the amino-benzyl sulphone. The dyestuffs dye or print protein fibres or synthetic linear polyamides from acid solution or dispersion to give blue shades. Reference has been directed by the Comptroller to Specification 917,104.
