ABSTRACT:
An ultraviolet curable clearcoat composition comprising (exclusive of any solvent present): (a) about 30% to about 90% by weight of an acrylated aliphatic urethane having a molecular weight of about 1200 to 2600 and formed by the reaction of a multifunctional acrylate with a molecular weight of between about 110 and about 500 with an aliphatic urethane based on a polyether and having a molecular weight of about 800 to about 2200; (b) about 15% to about 70% by weight of a multifunctional acrylate having a molecular weight of about 170 to about 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 clearcoated articles involving preferred clearcoat compositions.
