On the surface of 10 mm polyolefin resin, the thickness is 0.05 mm.
A synthetic resin FILNO is laminated on the surface of the -0, I mm iron-based metal plate, then the foil metal plate, via an adhesive layer, and the surface of the Synthesis 1 release film layer is exposed to ultraviolet rays. This is a 6'1-layer board consisting of a laminate consisting of a hardened resin layer and an adhesive layer that is bonded using polyurethane pressure-sensitive double-sided adhesive tape. The withering dates used as a layer were created by the applicant and the same applicant in 11r, 1986.
Defense of No. 078: Since the polyurethane pressure sensitive tape that can be used in Repetition 1 was used, there was a problem with productivity during the production of laminates, and if the 1+1fii ultraviolet curable resin layer became defective. ffF is stretched together with a synthetic resin layer.
