Ultraviolet light absorbing silicone compositions
First Claim
1. An ultraviolet light absorbing silicone composition comprising silicone base polymer selected from the group consisting of platinum catalyzed vinyl-hydride addition cured polydiorganosiloxanes and mixtures thereof and, covalently bonded thereto, ultraviolet light absorbing component derived from one or more vinyl functional, polymerizable ultraviolet absorbing monomers having the following structure:
- ##STR8## and mixtures thereof, wherein X is selected from the group consisting of H, alkoxy radicals and halogen, R1 is selected from the group consisting of H and alkyl radicals, provided that at least one of X and R1 is other than H, and R2 is an organic radical with a terminal double bond.

Abstract
An ultraviolet light absorbing silicone composition comprising silicone elastomer and, covalently bonded thereto, ultraviolet light absorbing component derived from one or more vinyl functional, polymerizable ultraviolet absorbing monomers having the following structures: ##STR1## and mixtures thereof, wherein X is selected from the group consisting of H, alkoxy radicals and halogen, R1 is selected from the group consisting of H and alkyl radicals, provided that at least one of X and R1 is other than H, and R2 and R are independently selected from organic radicals with a terminal double bond.
