Abstract: Disclosed is a continuous process for replicating interference patterns in radiation curable coating compositions or materials. Radiation curable coatings are brought into contact with interference patterns borne on the surface of an endless belt or revolving drum. The curable coating which may be supported by a substrate or unsupported is irradiated to cure it at least sufficiently so that it can be stripped from the replicating surface.

Abstract: A transferable film composition coated on a temporary support is used in the manufacture of heat and pressure consolidated laminates to produce laminates of improved surface strength and functional properties. The film is composed of polyvinyl butyral resin and melamine resin which reacts with a resin in the laminates. Additives may be included in the film composition for functional purposes and appearance.

Abstract: Disclosed in a process for producing gloss and smoothness on the surface of a paper web, comprising:A. advancing a web of papermaking fibers through a nip formed by a smooth metal finishing drum and a resilient backing roll; andB. heating the drum to a temperature at least high enough to heat a substrata portion of the web to a temperature in which gloss and smoothness rapidly increase with increasing temperature due to thermoplastic molding of the substrata beneath the surface and at a temperature higher than where substantial gloss and smoothness would have already been obtained by molding of the surface of the web.

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.

Abstract: 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.

Abstract: Apparatus for developing electrostatic images on electrophotographic material by means of a perforate development electrode and liquid toner, without immersing the material in a bath of toner.

Abstract: 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.

Abstract: Disclosed is a release coating provided by a coating composition having an acrylic functional component which has been polymerized by electron beam radiation. In a preferred embodiment the coating composition does not contain polysiloxane. In another preferred embodiment some of the acrylic functional component has one acrylic group per molecule and some has three or more acrylic groups per molecule before polymerization.
