<p>Provided is a method for producing a polyvinyl alcohol laminated paper, which is free of wrinkles and concave curls, whereby an aluminum vapor-deposited layer obtained by vacuum deposition of aluminum is disposed on the surface of a polyvinyl alcohol film, a water-based adhesive having a concentration of 40 to 60%, a viscosity of 500 to 4,000 mPa?s and a coverage of 3 to 5 g/m2 is applied to the reverse surface of the polyvinyl alcohol film, said polyvinyl alcohol film is laminated to a base paper, and a printed layer is formed by printing on the polyvinyl alcohol laminated paper. Alternatively, the water-based adhesive having a concentration of 40 to 60%, a viscosity of 500 to 4,000 mPa?s and a coverage of 3 to 5 g/m2 is applied to the reverse surface of the polyvinyl alcohol film, said polyvinyl alcohol film is laminated to a base paper, an aluminum deposition layer of a transfer foil obtained by vacuum deposition of aluminum is transferred to the polyvinyl alcohol film, and a printed layer is formed by printing on the polyvinyl alcohol laminated paper.</p> |
