ABSTRACT:
An ultraviolet curable coating composition having improved clarity and resin compatability is prepared by co-reacting an acrylate or methacrylate co-polymer containing hydroxy and carboxy groups with added polyol and maleic anhydride to form an unsaturated polyester, and then blending the unsaturated polyester with polyunsaturated monomers, monounsaturated monomers and a photoinitiator, all of which will cure when exposed to ultraviolet radiation.
