Description of the Related Art Conventionally, in order to prevent warpage of plywood, particle board and medium density fiberboard (hereinafter referred to as MDF), a paint such as a vinyl acetate resin emulsion is applied to both surfaces thereof, or a composite sheet of polyethylene film and paper. Alternatively, a composite sheet of aluminum foil and paper has been attached. However, in order to block the humidity by applying the coating material to the plate-like body, it was necessary to increase the amount of coating. However, the coating surface may be cracked by drying, and is not suitable for blocking the humidity. there were. In addition, since a polyethylene film alone has poor adhesiveness, a composite sheet of a polyethylene film and a paper is stuck. In this case, however, the adhesion between the synthetic resin film and the paper tends to peel off due to the penetration of humidity. There was a point. Moreover, although the composite sheet of aluminum foil and paper is stuck, the wooden sheet is excellent in preventing warpage, but when the edge of the wooden sheet is chamfered, the aluminum foil is applied to the edge. When the adhesive or the paint is applied, the brush or the like may be cut off by the aluminum foil, resulting in a problem that the workability is poor.

Olefin copolymers and the like can be mentioned. As the ethylene-vinyl acetate copolymer, those having a vinyl acetate content of 5 to 40% by weight, preferably 10 to 30% by weight are suitably used. When the vinyl acetate content is less than 5% by weight, the adhesiveness is poor, and when it exceeds 40% by weight, the workability deteriorates, which is not preferable.

It is preferable that a polyethylene-based resin is mixed because it is easy to handle when forming a film or when attaching a synthetic resin film. When the proportion of the ethylene-vinyl acetate copolymer is less than 30% by weight, the adhesiveness becomes weak, so that a pretreatment such as a corona treatment is previously required on the film surface, which is not preferable in terms of workability and cost.

た。ソリの程度は３５ｍｍであった。Comparative Example 2 A flash panel was produced in the same manner as in Example 3 using MDF to which the laminated sheet of polyethylene film and thin paper obtained in Comparative Example 1 was adhered, and warpage was produced in the same manner as in Example 1. Tested. First, the thin paper outside the polyethylene film in contact with the humidity of 70% peels off, and the thin paper on the bonding surface between the film and the plate-like substrate progresses from the periphery of the sheet. Peeling was observed in 20%. Warpage was observed at the peeled portion. The degree of warpage was 35 mm.
