摘要： A molded article of plastic having on its surface a cured film of a coating material comprising at least 30% by weight of at least one polyfunctional compound selected from the group consisting of poly-methacryloyloxy compounds having a molecular weight of 250 to 800 and containing at least three methacryloyloxy groups in the molecule and poly-acryloyloxy compounds having a molecular weight of 250 to 800 and containing at least three acryloyloxy groups in the molecule, and optionally 0.01 to 5% by weight of a fluorine-containing surfactant and 0.01 to 5% by weight of a carbonyl compound as photosensitizer has improved surface characteristics, particularly a high surface hardness, a high surface smoothness, high heat resistance, high abrasion resistance and a minimized optical distortion. Said molded article of plastic having improved surface characteristics can be prepared by coating the molded substrate of plastic with said coating material to a thickness of 1 to 50.mu. and then subjecting the coated article to a light of 2,000 to 8,000 A in an inert atmosphere to cure the coating material.
