ABSTRACT:
The invention is directed to a coating system which is adaptable to being crosslinked subsequent to being embossed. The system comprises a linear polyurethane that contains sites of unsaturation only in its polymeric backbone and a photoinitiator. The polyurethane is produced by the reaction of a diisocyanate and an unsaturated polyester diol.
