PROBLEM TO BE SOLVED: To enhance transparency, barrier properties, impact resistance, laminat ing strength or the like, by providing a membrane of inorg. oxide, a coating membrane of a polyurethane resin compsn. and a printing pattern layer on the surface of a flexible plastic substrate successively, and providing a heat- sealable resin layer on the entire surface of the printing pattern layer. SOLUTION: A membrane 2 of inorg. oxide is provided on one surface of a flexible plastic substrate 1, and a coating membrane 3 comprising a polyurethane resin cimpsn. containing a silane coupling agent and a filter is provided thereon. Further, a printing pattern layer 4 comprising an ink compsn. based on a polyurethane resin and vehicle is provided on the surface of the membrane 3, and a heat-sealable resin layer 6 is laminated on the entire surface through an one to two-pack type curable polyurethane laminating adhesive layer 5. As the silane coupling agent, binary reactive organofunctional silane monomers can be used and, and the filler, for example, calcium carbonate, barium sulfate, alumina white, silica, talc and the others are designated. |
