ABSTRACT:
Resinous articles, especially polycarbonate articles, coated with an abrasion-resistant surface coating such as a silicone hardcoat, contain a primer coat between the article and the surface coating, said primer coat being a copolymer of a monomer mixture including an ethylenically unsaturated monomer having an ultraviolet degradation inhibiting moiety, preferably a 4-(2-hydroxybenzophenone)oxy moiety. The articles are characterized by improved hardcoat adhesion and resistance to discoloration and ultraviolet degradation.
