Patent ID: 8513321

Claim:
A dual cure coating composition comprising: (a) a melamine-group containing polyethylenically unsaturated compound; and (b) an acrylate-containing composition comprising: (i)a urethane acrylate, (ii) an epoxy acrylate, and (iii) a multi-functional acrylate monomer; wherein the acrylate-containing composition (b) is present in the dual cure coating composition at a level sufficient to provide a cured coating layer deposited from the coating composition having a glass transition temperature (Tg) of 100° C. or below and a crosslink density of 20.0 mmoles/cc or below, and wherein the dual cure coating composition is curable by exposing the coating composition to thermal energy followed by radiation wherein the urethane acrylate comprises a polycarbonate urethane acrylate and a polyester urethane acrylate.
