Procedure

A solution prepared by adding 0.02 part of methoquinone to a mixture comprising 24 parts of 1,4-diaminoanthraquinone and 70 parts of glycidyl methacrylate and dissolving the obtained mixture in 1000 parts of methanol was stirred under reflux for 8 hours. After the completion of the reaction, the reaction mixture was distilled to remove the methanol. The obtained viscous solid was subjected to extractive washing with petroleum ether to give a blue polymerizable anthraquinone dye D. The anthraquinone dye D is represented by the below chemical formula (V). ##STR5##
