The one described in Japanese Patent Laid-Open No. 3-56447 is a method of laminating a paper and an acrylic film with an adhesive,
Although thermal adhesion by heating and pressing is mentioned, the use of an adhesive causes problems such as generation of organic solvent gas and durability of the adhesive. Further, according to the method described in Japanese Patent Publication No. 56-13724, the fibrous substance is dispersed in the resin and becomes whitish as a whole, and the shoji-like decorative effect is not obtained, and the resin remains after molding by molding. There is a problem of lack of dimensional stability due to residual stress.
