Versuchsvorschrift

Twenty-five parts of 1,2,4-trihydroxy-anthraquinone, 45 parts of dimethylaminopyridine and 0.01 part of methoquinone were dissolved in 1000 parts of dried dichloromethane and the obtained solution was cooled with ice in a nitrogen atmosphere. Then, 25 parts of acryloyl chloride was dropped into the resulting solution. After the completion of the dropping, the obtained mixture was stirred under reflux for 8 hours. The reaction mixture thus obtained was washed with water, dried and distilled to remove the solvent. Thus, a yellow polymerizable anthraquinone dye C was obtained. The anthraquinone dye C is represented by the below chemical formula (IV). ##STR4##
