ABSTRACT:
Disclosed is an improved method of providing a desired surface effect in a release coating including the steps of applying a coating of an electron beam radiation curable composition or material to a side of a substrate, pressing the coated side of the substrate against a replicative surface having the desired surface effect, and irradiating the coating with electron beam radiation through the substrate to partially cure the coating sufficiently to enable it to be removed with the substrate from the replicative surface securely attached to the substrate and with the replicated surface effect in the coating being maintained, the improvement being the further step of irradiating the coating a second time, preferably from the other side, with electron beam radiation without first applying additional coating. Also disclosed is the resulting product.
