MANUFACTURE OF SURFACE HARDENING SYNTHETIC RESIN MOLDED FORM

PURPOSE: To raise degree of adhesion between mold containing polymerizing double bond and adhesion layer and to improve durability against wearing, scratches and chemicals by using transcription sheet with adhesion layer consisting of ionizing radiation hardening resin unhardened, and by cross-linking the both with irradiation of ionizing radiation. CONSTITUTION: Method for producing surface reinforced plastic mold is to superpose surface of protected layer 5, consisting of ionizing radiation hardening resin on mold-lubricating surface of mold-lubricating sheet 2, of transcription sheet A on plastic mold 3 with polymerizing double bond, followed by irradiation of ionizing radiation from at least one side of the obtained laminate to peel off the mold-lubricating sheet 2. Used as the mold-lubricating sheet 2 is a film composed of plastics of polyolefin such as polyester, polypropylene and polyethylene, or a polyamide such as nylon, paper, synthesized paper and others. Besides, the ionizing radiation hardening resin forming the protecting layer 5 is resin that is hardened with ionizing radiation such as ultraviolet rays or electron beam, and mixture of prepolymers, oligomers or the like that contain ethylene type unsaturated bonds in the molecule.
