Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention belongs to the technical field of ball-and-ball game machines, and more particularly to a cosmetic material to be stuck on the surface of a game board.

[0002]

[Prior art]

 In ball game machines represented by pachinko machines, prize winning devices, obstacle nails, windmills, etc. are installed on the game board, and it is determined whether or not the game ball will contact the prize devices and change the course and win. Or a winning device depending on which winning device is won.

Generally, a game board is made of plywood, and a decorative material on which various designs and the like are drawn is stuck on the surface thereof. Cosmetic materials are hard-to-scratch even when they come in contact with game balls, and they are hard to be damaged by hitting nails or cutting out in response to winning holes, etc. Because of the demand for printability, which is easy to perform, celluloid sheets or sheets obtained by impregnating paper with melamine resin have been used.

[0005] However, since the mere printing is a two-dimensional expression, the decorative effect is also limited. For this reason, a decorative material provided with a hologram layer has been proposed as a technique for imparting three-dimensionality to the decoration of a decorative plate to enhance the decorative effect (for example, Japanese Utility Model Laid-Open No. 5-85631, Utility Model Registration No. 3009525). .

[0005]

[Problems to be solved by the invention]

 However, when manufacturing cosmetic materials described in Japanese Utility Model Laid-Open No. 5-85631 or Utility Model Registration No. 3009525, it is necessary to bond paper with a hologram layer and bond a transparent plastic or celluloid sheet as a surface layer. Is required.

However, any kind of adhesive may be used for the bonding (Japanese Utility Model Laid-Open No. 5-85631 and Utility Model Registration No. 3009525) do not disclose the components or compositions of the adhesive. ), The application (dispersion) of the adhesive is not uniform, and the aesthetic appearance of the cosmetic material cannot be secured, and the adhesive strength is weak. Could not be manufactured.

Further, if a paper having a small surface roughness, such as glossy paper, is used in an attempt to equalize the dispersion of the adhesive on the bonding surface with the paper, the bonding between the paper and the plywood of the game board is not good. There were also problems. An object of the present invention is to provide a cosmetic material having a hologram layer, which has both sufficient strength for practical use and good aesthetic appearance.

[0008]

[Means for Solving the Problems]

 A cosmetic material for a game board according to claim 1 for solving the above-mentioned problem is a cosmetic material to be stuck to a game board of a ball-and-ball game machine, the lowermost layer material being attached to one side of the game board. And a hologram layer disposed between the paper and the uppermost layer material, wherein the uppermost layer material and the uppermost layer material are provided. An acrylic emulsion adhesive is used for bonding to the paper layer.

The decorative material for a game board according to claim 2 is the decorative material for a game board according to claim 1, wherein the hologram layer is provided on one side of the polyester resin film, and the hologram layer is provided on the paper side. The polyester resin film and the paper are arranged between the paper and the uppermost layer material, and the uppermost layer material and the polyester resin film are adhered to each other with the acrylic emulsion adhesive. It is characterized by having been attached at.

[0010]

[Embodiment of the invention]

 The decorative material of the present invention has a laminated structure in which a hologram layer is arranged between paper as the lowermost material and the uppermost material. The paper quality of the paper as the lowermost layer material is not particularly limited, but considering the adhesion to the plywood of the game board, it is preferable that the surface roughness is not small. The paper color is preferably white, but may be partially colored by printing or the like according to the design or the like, or may be a paper color other than white.

The hologram layer can be provided on a synthetic resin film such as the polyester resin film described in claim 2 or on paper or the uppermost layer material. When provided on a synthetic resin film, the hologram layer may be formed directly on the synthetic resin film. Alternatively, it may be transferred to the uppermost layer material. The structure and manufacturing method of the hologram layer may be in accordance with known techniques.

The hologram layer may be provided on the entire surface of one surface of a synthetic resin film such as paper, the uppermost layer material, or a polyester resin film, or may be provided only on a part thereof. When the hologram layer is provided on paper, the decorative material is completed by bonding the uppermost layer material to the hologram layer side, and when the hologram layer is provided on the uppermost layer material, the decorative material may be bonded to paper. When the hologram layer is provided on the synthetic resin film, the synthetic resin film and paper are bonded and laminated, and the uppermost layer material is bonded and laminated thereon.

If the uppermost layer material is colored by printing or transfer, the decorative effect can be enhanced in cooperation with the hologram layer. Since the surface of the uppermost layer material comes into contact with the game ball, it is preferable that printing or the like be provided on the back surface (the surface that becomes the inside during lamination). Further, the printing or the like may be provided on the entire back surface or may be provided only on a part thereof.

Since the non-stretched sheet of the copolymerized polyester resin has no orientation, no tears or the like are generated even if a nail is driven or a cutout for mounting a winning device is performed. Therefore, nailing and drilling can be performed after the cosmetic material is attached to the game board.

When an acrylic emulsion adhesive is used for a non-stretched sheet of a copolymerized polyester resin, the adhesive is uniformly dispersed over the entire surface without impairing the appearance of the decorative material. Also, the adhesive strength is sufficient. A typical example of the unstretched sheet of the copolymerized polyester resin is Spectar (trade name) copolyester sheet 14471 manufactured by Eastman Chemical Company. The physical properties of Spectar (trade name) copolyester sheet 14471 (hereinafter referred to as PETG) are as shown in Table 1 below.

[0016]

[Table 1]

As is clear from Table 1, this PETG is excellent in mechanical strength and also excellent in elasticity and flexibility. Also, since it is an unstretched sheet, there is no residual orientation or stress due to stretching, and when a hole in a prize winning device or the like is drilled or an obstacle nail is driven, it breaks or grows from these mechanical wounds. Never. In addition, it is sufficiently flexible, has good compatibility with a plywood game board, and there is no fear that the rebound of a game ball becomes too strong.

In addition, various known printings such as offset printing, gravure printing, silk screen printing, and UV printing can be performed on the PETG. In addition, any ink suitable for acrylic or polycarbonate can be used without any problems, and there is no need to use special inks.

When a polyester resin film having a hologram layer provided on one side is used, the uppermost layer material and the ester resin film are bonded with an acrylic emulsion adhesive, and the polyester resin film and paper are converted into a modified polyester resin film. When bonded with an adhesive, the dispersion of the adhesive between the layers becomes excellent and uniform, and the adhesive strength is sufficient. Therefore, the appearance is not impaired and the adhesive strength is sufficient for practical use.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the decorative material 1 of this example includes the above-described PETG top layer material 10, a hologram holding layer 12 of a polyester resin film, a hologram layer 12a provided on the hologram holding layer 12, and a paper 14. The printing 10a is applied to the back surface of the uppermost layer material 10.

The decorative material 1 is formed by laminating a hologram holding layer 12 on which a hologram layer 12a is already provided in the same manner as a roll of paper 14 with a modified polyester adhesive to form a laminated material. It is manufactured by adhering an uppermost layer material 10 on which sheets 10 have already been printed 10a with an acrylic emulsion adhesive.

In this example, as the modified polyester-based adhesive, an elastomer (trade name: EPS75A, Takeda Pharmaceutical) and a curing agent (trade name: KW40, Takeda Pharmaceutical) were mixed at a ratio of approximately 5: 1. A component adhesive was used. As the acrylic emulsion adhesive, trade name SA-T630W (Tokyo Ink) was used. As the acrylic emulsion adhesive, trade name SA-T610W (Tokyo Ink) can be used.

Then, the decorative material 1 was stuck on the surface 16 a of the game board 16, and holes for a prize device and the like were driven into the hole, but obstacles such as tears did not occur. In addition, the laminated structure was not destroyed (partially peeled or wrinkled) around the hole. The appearance of the decorative board 1 was also good.
