Procedure

2.44 parts of 1,5-diamino-4-(3-dimethylamino-propylamino)-2-methoxy-anthraquinone prepared from 1,5-diamino-4-(3-dimethylamino-propylamino)-9,10-dioxo-9,10-dihydro-anthracene-2-sulfonic acid and methanolic potassium hydroxide at 95° C. were dispersed in 50 parts of diglyme and treated with 0.75 part of dimethylsulfate. The reaction mixture was kept for 3 hours at room temperature. The precipitate was filtered off and washed with acetone. Upon drying 2.8 parts of the dye of formula Iz were obtained. The blue dye Iz is very good water-soluble. The analytic data are consistent with the assigned structure for dye Iz.
