(57) [Summary] [Purpose] A novel silylated drug capable of absorbing ultraviolet light. The silylated agent of the present invention is 4,6-dibenzoyl-2- (trialkoxysilylalkyl) resorcinol, which is stable to light and compatible with silicone hardcoat matrices. The novel silylated drug is incorporated into a silicone hard coat and used to coat a polycarbonate substrate. The polycarbonate substrate thus coated exhibits improved resistance to abrasion and UV light. |
