ABSTRACT:
The invention is directed to an embossed material and a method of producing such an embossed material by utilizing 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. The coating system is applied to a substrate, is embossed, and is irradiated to crosslink the polyurethane coating and permanently fix the embossed pattern.
