Abstract

PURPOSE:To obtain the titled processed article excellent in shape retention, by applying a coating layer comprising a binder resin, a filler, and an electron beam-curable resin to the surface of a plastic sheet, forming this sheet into the desired shape and irradiating the formed sheet with electron beams. CONSTITUTION:To the surface of a plastic sheet such as polypropylene or polystyrene film is applied a coating layer comprising a binder resin (e.g., polyethylene or polyacrylate ester), an organic filler (e.g., crosslinked polystyrene or urea resin) or an inorganic filler (e.g., calcium carbonate or alumina), and an electron beam-curable resin (e.g., carbitol acrylate or pentaerythritol triacrylate). The sheet to which the coating layer is applied is formed into a desired shape by application of heat and/or pressure, and the coating layer is cured by irradiation with electron beams to obtain the purpose processed plastic product.
