Versuchsvorschrift
1-Amino-2-carboxy-4-(3'-amino-4'-sulfophenylthio)anthraquinone (9.4 parts) and cyanuric chloride (3.7 parts) were subjected to condensation reaction in an aqueous medium in a usual manner, followed by a condensation reaction with 3-aminobenzenesulfonic acid (3.5 parts) at 20° to 40° C. under a weak acid condition, thereby obtaining an anthraquinone compound of the following formula (free acid form). ##STR394##
