る。(Operations and Effects of the Invention) In the method of the present invention, the protective film used when manufacturing a building material by laminating and hot pressing a plate-like body having an embossed PVC layer and a core material is a base material layer and an intermediate layer. The polyethylene or ethylene-vinyl acetate copolymer used for the intermediate layer melts at a temperature lower than 160°C. If heated and pressed at a high temperature, the unevenness of the embossing will be fixed in the melted intermediate layer together with the adhesive layer.Then, the adhesive strength between each layer of the embossing will be P
The adhesive strength is stronger than that between the VC layer and the adhesive layer, combined with the rigidity of the base layer, and it can be easily peeled off at the interface between the enhanced surface of the PVC layer and the adhesive layer, so the original A building material with an excellent decorative effect and a good appearance while maintaining the embossment can be obtained.
