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.

Method of providing a surface effect in a release paper product

Disclosed is 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 from the replicative surface securely attached to 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.

Surface replication on a coated substrate

Disclosed is a release coating composition having acrylic functional materials which have been polymerized by electron beam radiation, about 15% to about 85% of the acrylic functional material being provided by one or more aliphatic noncyclic monofunctional acrylates and the remainder of the acrylic functional material being provided by one or more multi-functional acrylates.

Disclosed is a superior method of providing a desired surface effect in a release coating on a substrate by providing a coating of an electron beam radiation curable composition or material between one side of the substrate and a replicative surface having the desired surface effect, and 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 from the replicative surface. Also disclosed is the apparatus for carrying out the method and the resulting product.
