CHEMICAL MODIFICATION TO BIS TYPE STRUCTURE BY ADIPOYL DICHLORIDE, ISOPHTHALOYL DICHLORIDE OR TEREPHTHALOYL DICHLORIDE OF BENZOTRIAZOLE-BASED ULTRAVIOLET LIGHT ABSORBENT HAVING HYDROXYMETHYL GROUP

摘要

PROBLEM TO BE SOLVED: To synthesize a benzotriazole-based ultraviolet light absorbent improved in transpiration resistance and being free from problem also in compatibility, etc.;SOLUTION: The problem is solved by chemical modification to a bis type structure by adipoyl dichloride, isophthaloyl dichloride or terephthaloyl dichloride of a benzotriazole-based ultraviolet light absorbent having a hydroxymethyl group.;COPYRIGHT: (C)2009,JPO&INPIT
