Procedure

6.6 parts of 1,5-diamino-4-(2-dimethylamino-ethoxy)-anthraquinone prepared from 1,5-diamino-4-chloro-anthraquinone, N,N-dimethylaminoethanolamine and metallic sodium at 95-120° C. were dispersed in 75 parts of chlorobenzene and treated with 1.4 parts of dimethylsulfate. The reaction mixture was kept for 1½ hours at room temperature. The precipitate was filtered off and stirred with 150 parts of water followed by filtration. The filtrate was evaporated in vacuo yielding 2.5 parts of the dye of formula Ik. The red dye Ik is very good water-soluble. The analytic data are consistent with the assigned structure for dye Ik.
