Versuchsvorschrift

1-Amino-2-bromo-4-(3'-amino-4'-sulfophenylthio)anthraquinone (10.1 parts), cyanuric chloride (3.7 parts) and 1-aminobenzene-4-β-sulfatoethylsulfone (5.6 parts) were subjected to condensation reactions one after another in an aqueous medium in a usual manner, followed by a condensation reaction with 3-aminobenzenesulfonic acid (3.5 parts) at 50° to 70° C. under a weak acid condition. Thereafter, salting out of the reaction mixture gave an anthraquinone compound of the following formula (free acid form). ##STR322##
