Description

Laminated body, decorative shaped body and manufacturing method of decorative shaped body

The invention relates to a laminated body and a decorative shaped body. Specifically, the present invention relates to a laminated body having a surface layer, an adhesive layer, and a separator layer, and capable of suppressing the invasion of foreign matter when forming under a vacuum condition or a reduced pressure condition. Further, the present invention relates to a decorative molded body decorated with such a laminated body. This application claims priority based on Japanese Patent Application No. 2015-013331 filed on January 27, 2015, and incorporates the contents thereof.

Conventionally, when protecting and decorating the surfaces of automobile interior and exterior parts, home appliance parts, and building material parts, the formed body is processed by injection molding or vacuum forming, and then spray-coated. The surface of the molded body is coated with a coating material, and dried and heated to harden. However, this kind of coating has the problem that the discharge of volatile organic solvents deteriorates the working environment. In addition, because the working steps and production equipment of each formed part are required, and the coating is overlapped, the yield of the coating is poor. Sexual problems.

In recent years, for the purpose of weight reduction of automobile interior and exterior parts, home appliance parts, and building material parts, the use of resin molded articles as molded articles is developing. In the decoration of a resin molded body, spray coating is not suitable in many cases. In order to decorate the surface of the resin molded body, various methods have been developed. Among them, the method of decorating the outermost surface of the formed body with a decorative film to obtain a decorative formed body is more effective than using The method of coating or printing the surface with a paint or the like has the advantages of high design freedom and excellent productivity. In addition, the decoration method using a decorative film can also decorate the surface of a molded body having three-dimensional irregularities, and thus can be used for various purposes.

As a method of decorating the surface of a molded body having three-dimensional unevenness with a decorative film, there is a method of three-dimensional covering molding (TOM molding) (Patent Document 1). TOM molding is a molding manufacturing method under a vacuum condition or a reduced pressure condition, and it is a method of pressing a decorative film and a molded body to obtain a decorative molded body. TOM molding can be decorated regardless of the material of the molded body. In addition, it is possible to cover the molded body by forming the inverted tapered portion and the end band portion without providing a vacuum hole.

Among the decorative films used for TOM, there are a film having only a decorative layer, and a laminated film (laminate) having a decorative layer (surface layer) and an adhesive layer. When a decorative molded body is obtained using a film having only a decorative layer, a method of melting the film itself and bringing the molten film into close contact with the molded body can be used. When a laminated film having a decorative layer (surface layer) and an adhesive layer is used, there is no need to melt the decorative layer, and the laminated film is brought into close contact with the molded body by the adhesive force of the adhesive layer.
