Abstract: The present invention relates to a composition for coating substrates and to methods for coating substrates using the composition. In general, the composition contains a prepolymer and a decorative effect additive, such as a pigment. The composition is radiation curable. In one embodiment, the composition is cured by electron beam energy. In another embodiment, the composition also contains a photoinitiator and is cured by ultraviolet (UV) energy. The composition coats substrates via a single curing process to provide a decorative coating, also referred to as a non-clear coat.

Abstract: Described are preferred UV curable coating compositions which are suitable for use as basecoats in the production of lamp reflectors. Also described are reflector devices and methods for making them.

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.
