Procedure

Example 25 was repeated, except that the compounds shown in 1st, 2nd and 3rd columns of the following table were used in place of the 1-amino-4-(3'-amino-2',4',6'-trimethyl-5'-sulfophenylthio)anthraquinone-2-sulfonic acid, 1-aminobenzene-3-β-sulfatoethylsulfone and 3-aminobenzenesulfonic acid, respectively, thereby obtaining a corresponding anthraquinone compound. The color shade on cotton of the compound is as shown in a 4th column of the table.
