Abstract
Coated polycarbonate articles, such as sheet and film, are coated with a hard, abrasion and chemical resistant coating which is the photoreaction product of an acrylated urethane oligomer, a difunctional acrylate monomer and preferably also a monofunctional olefinic monomer. These coated articles may be thermoformed or flexed without cracking or delamination of the protective coating. A specific embodiment of the invention is a coated flexible siloxane-polycarbonate block copolymer.
