RELEASE SHEET AND METHOD AND APPARATUS OF PROVIDING SURFACE REPLICATION IN A RELEASE COATING

摘要

There is disclosed a superior method of providing a desired surface effect in a release coating on a porous sheet-like substrate by applying a coating of an electron beam radiation curable composition or material directly to one side of a base coated paper web, pressing the coated side of the substrate against a replicative surface having the desired surface effect, irradiating the coating with electron beam radiation through the substrate to cure the coating at least sufficiently to permanently adhere it to the substrate and to enable it to be removed with the substrate and with the replicated surface effect in the coating being maintained, the irradiation step taking place after sufficient time has passed to cause the coating to penetrate into the coated paper and to be in continuous intimate contact with the coated paper. Also disclosed is the apparatus for carrying out the method and the resulting product.
