ABSTRACT:
Actinic radiation curable coating compositions applicable to many substrates and comprising a pentaerythritol-based polyacrylate or polymethacrylate such as pentaerythritol tetraacrylate, a vinyl chloride-vinyl acetate containing polymer, preferably a partially hydrolyzed vinyl chloride-vinyl acetate copolymer, and a photoinitiator are provided. The compounds are preferably applied to the substrate by spraying a solution of the composition in one or more solvents selected from the group consisting of lower alcohols and ester, ketones having from 3 to 7 carbon atoms and lower alkyl Cellosolves, and removing the solvents. Upon curing in air the compositions form extremely abrasion resistant coatings on the substrate.
