ABSTRACT:
Plastic articles can be coated with polymerizable compositions containing a vinyl-functional crosslinkable film former, a large amount of benzotriazole and a copolymerizable monomer that solubilizes the benzotriazole. The cured compositions help protect the article from UV exposure and other weathering effects.
