Abstract
A gloss coating composition comprising radiation curable oligomers and monomers, and photosensitizers in a homogeneous mixture having a viscosity in the range of 4500 to 8000 cps; wherein the presence of the photosensitizers causes polymerization of the radiation curable oligomers and monomers when exposed to an ultraviolet light source. The coating composition is applied to at least one surface of a substrate and exposed to an ultraviolet light source resulting in curing of the composition onto the substrate surface without substantial penetration into the substrate surface forming a gloss coated substrate.
