UV-CURABLE COATING COMPOSITION USEFUL AS TOP SURFACE COATING FOR PLASTIC SUBSTRATE AND MOLDED ARTICLE COMPRISNG A CURED COATING LAYER FORMED FROM THE SAME

摘要

The present invention relates to a molded article comprising an ultraviolet curable coating composition useful for surface coating of a plastic substrate and a cured coating layer formed therefrom, and more particularly, a multifunctional aliphatic urethane acrylate oligomer or a benzotriazole modified aliphatic urethane. It includes acrylate oligomers, polyfunctional acrylate monomers, photopolymerization initiators, ultraviolet absorbers and light stabilizers, and has excellent adhesion and heat resistance to plastic materials, in particular polycarbonate (PC) materials, and abrasion resistance, high hardness, chipping resistance and The present invention relates to a molded article comprising an ultraviolet curable coating composition having excellent weather resistance and useful for surface coating of a plastic material for glass replacement products, such as a PC lens of an automobile head lamp, in particular, a cured coating layer formed therefrom.
