ABSTRACT:
The present invention is directed to a non-aqueous composition curable by UV radiation broadly comprising a mixture of two UV curable urethane acrylates. The invention is also directed to a coating process using such composition. One of the urethane acrylates is the reaction product of an isocyanate and a specific OH functional lactone ester (meth)acrylate. The other urethane acrylate is the reaction product of an isocyanate and a specific hydroxy functional (meth)acrylate.
