HCID 6780Anthraquinone

Procedure

Example 19 was repeated, except that the compounds shown in 1st and 2nd columns of the following table were used in place of the 1-amino-2-carboxy-4-bromoanthraquinone and 4-(4'-β-hydroxyethylsulfonylphenoxy)thiophenol, respectively, thereby obtaining a corresponding anthraquinone compound. The color shade obtained by dyeing cotton with the compound is as shown in a 3rd column of the table.
