反応手順
1-Amino-2-(3'-amino-4'-sulfophenoxy)-4-(4'-sulfophenylthio)anthraquinone (6 parts) and cyanuric chloride (1.8 parts) were subjected a to condensation reaction in an aqueous medium in a conventional manner, followed by a condensation reaction with 3-aminobenzenesulfonic acid (1.7 parts) at 20° to 40° C. under a weak acid condition. Thereafter, salting out of the reaction mixture with sodium chloride gave an anthraquinone compound of the following formula (free acid form). ##STR215##
