ABSTRACT:
Actinic radiation curable coating compositions are provided requiring no photoinitiator or photocatalyst which are applicable to many substrates comprising a dipentaerythritol-based polyacrylate such as dipentaerythritol pentaacrylate, a cellulose ester such as cellulose acetate butyrate or a vinyl chloride-vinyl acetate containing copolymer. 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 esters, ketones having from 3 to 7 carbon atoms and lower alkyl Cellosolves, and removing the solvents. Roller gravure coatings may also be employed.
Upon curing in air the compositions form extremely high abrasion resistant coatings on the substrate and are also characterized by being scratch resistant and resistant to attack by chemical and organic solvents and are stress crack resistant.
