Coating compositions and method for the surface protection of plastic substrate

摘要

A composition comprising (1) 0.1-50 parts by weight of the reaction product of a hydroxyl group-containing benzophenone compound with a silane and/or a hydrolyzate thereof and (2) 100 parts by weight of a silane compound and/or a hydrolyzate thereof is applied to a polycarbonate sheet to form a protective coating having mar and weather resistance. A composition comprising the reaction product of a hydroxyl group-containing benzophenone compound with a silane and/or a hydrolyzate thereof is useful for undercoating.
