SYNTHESIS OF 2-4-(2H-BENZOTRIAZOL-2-YL)-3-HYDROXYPHENOXY-4,6-DIALKOXY-1,3,5-TRIAZINE AND 2-4-(2H-BENZOTRIAZOL-2-YL)-3-HYDROXYPHENOXY-4,6-BISARYLOXY-1,3,5-TRIAZINE AND USE AS ULTRAVIOLET LIGHT-ABSORBING AGENT

摘要

PROBLEM TO BE SOLVED: To provide a benzotriazole-based ultraviolet light-absorbing agent without having a difference in compatibility, chemical stability, light stability and heat stability (a high temperature stability), but highly improved with transpiration resistance widely.;SOLUTION: The 2-[4-(2H-benzotriazol-2-yl)-3-hydroxyphenoxy]-4,6-dialkoxy-1,3,5-triazine and 2-[4-(2H-benzotriazol-2-yl)-3-hydroxyphenoxy]-4,6-bisaryloxy-1,3,5-triazine are obtained by performing the dehydrochlorinative condensation of 2-chloro-4,6-dialkoxy-1,3,5-triazine or 2,4-bisaryloxy-6-chloro-1,3,5-triazine with 4-(2H-benzotriazol-2-yl)resorcinol which is easily produced in a large amount.;COPYRIGHT: (C)2007,JPO&INPIT
