ABSTRACT:
Described is a preferred UV curable coating composition comprising (exclusive of any solvent present): (a) about 5% to 90% by weight of an acrylated aliphatic urethane having a molecular weight of about 500 to 2000 and formed by the reaction of a multifunctional acrylate with a molecular weight of about 190 to 500 and containing at least three polymerizable unsaturated groups per molecule, with an aliphatic urethane based on a polymer of alkyl carbomonocycle diisocyanate with alkanepolyol polyacrylates; (b) about 5% to 30% by weight of a multifunctional acrylate having a molecular weight of about 170 to 1000 and containing at least two polymerizable unsaturated groups per molecule; and (c) a photopolymerization initiator and/or sensitizer. Also described are preferred processes and coated articles involving the preferred coating compositions.
