ている。On the other hand, vinylidene fluoride resin and vinylidene fluoride resin are excellent in weather resistance, stain resistance, chemical resistance, etc., and in recent years, demands for building use, equipment use, and transport use have been increasing. It is used in the form of a film or paint.

Adhesion with the vinyl resin sheet is insufficient. In the case of a two-layer film having a vinylidene fluoride homopolymer as a surface layer and a methacrylic resin layer as an adhesive surface layer, there is no problem in adhesion to a vinyl chloride resin sheet. When used in the form of a film, such as a mixture of vinylidene homopolymer and methacrylic resin and a two-layer structure of vinylidene fluoride homopolymer and methacrylic resin, it is expensive in price and cannot be said to be economically satisfactory. .

非常に困難である。Further, in the case of a paint, a high-temperature baking type cannot be applied unless the base material, such as a metal or an inorganic board, can withstand a long time under a high temperature. In addition, the room temperature drying type requires several minutes to several tens of minutes for touch drying, and is not suitable for endless production.
Therefore, it is very difficult to provide an endless top coat layer on the surface of the vinyl chloride resin sheet with any type of paint.

のである。The present invention focuses on this point, and as a result of repeating various studies,
An acrylic polymer containing a carboxyl group that has good adhesion to a vinyl chloride resin sheet and vinylidene fluoride resin and can be a binder for ink that can be printed on the vinyl chloride resin sheet has been found. After providing a top coat layer with a vinylidene resin dispersion, the vinylidene fluoride (system) resin coating film containing carboxyl groups is heated and pressurized by embossing from the surface of the vinylidene fluoride (system) resin coating film. This is achieved by finding that the adhesiveness of each interface between the acrylic polymer and the vinyl chloride resin sheet can be enhanced, and peeling of the vinylidene fluoride (based) resin coating film can be prevented very effectively.
