[Problems to be solved by the device]

 However, in the above-mentioned conventional display panel, since the adhesive layer is provided on the surface of the synthetic resin foam, it is possible to easily attach the poster, etc. to the panel, but the poster etc. If you peel off the bulletin board and try to stick another bulletin board, the adhesive will stick to the back side of the bulletin board that was previously stuck and peel off from the panel. When the bonding failed, it was impossible to re-bond or repeatedly use the panel. Also, in the above-mentioned conventional display panel, the adhesive layer is formed directly on the surface of the synthetic resin foam, so when sticking paper, etc., air can easily accumulate, leaving traces of air bubbles on the surface, making paper etc. clean. It is difficult to stick to the surface of the synthetic resin foam, and in the case of a single-sided adhesive processed product, the surface of the synthetic resin foam on which the adhesive layer is not formed is exposed to static electricity, and the dirt is conspicuous. There is a problem that the surface of the synthetic resin foam is not suitable for handwriting or printing. Further, in the case of manufacturing a conventional panel, a drying process of drying the pressure-sensitive adhesive in a drying furnace for a long time is required, which has a drawback of low production efficiency. The present invention solves the above-mentioned drawbacks of the prior art, and an object thereof is to provide a simple display panel that can be repeatedly used.

Further, the shape, size, etc. of the display panel of the present invention are not particularly limited, and the shape and size may be appropriately determined according to the application etc.

As the plate-shaped core material 2, a polystyrene resin foam having a thickness of about 0.5 to 50 mm, a cardboard, a plastic plate or the like is used, but the polystyrene resin foam is superior in water resistance to paper, It is lighter than a plastic plate and is preferable in that it has both water resistance and light weight. The adhesive layer 3 is an emulsion type such as acrylic emulsion or vinyl acetate emulsion, natural rubber type, synthetic rubber type, polyurethane type, vinyl solvent type, phenol type, melamine type, acrylic type, epoxy type, ethylene-vinyl acetate copolymer It is possible to use a hot melt type such as a combined hot melt. As the paper sheet 4, paper such as Kent paper and high-quality paper is appropriately used. Further, the paper sheet may be provided with printability, writing ability, or the like on the surface.

The removable pressure-sensitive adhesive layer 6 does not leave an adhesive on the adherend when the adherend adhered to the pressure-sensitive adhesive layer 6 is peeled off, and the adherend can be peeled off cleanly. What is necessary is just to use a conventionally known removable adhesive. Examples of such removable adhesives include acrylic emulsion type and natural rubber latex type, but acrylic emulsion type is preferred, and the thickness of the adhesive layer 6 is appropriately selected within a practical range. 1 to 100 μm is preferable, and 1 to 10 μm is particularly preferable.

The peelable sheet 7 is provided for the purpose of covering the removable pressure-sensitive adhesive layer 6 and protecting the pressure-sensitive adhesive layer 6 from dirt and the like before the panel 1 is used. Paper, film or the like subjected to the above is used. When a panel is used, the peelable sheet 7 is peeled off to expose the surface of the pressure-sensitive adhesive layer for use.

Next, an example of using the display panel of the present invention will be described. Display panels at exhibitions, stores, etc. By using the display panel of the present invention in which peelable adhesive layers are provided on both sides (double-sided type), the back side of the panel is attached to the wall, and photos and posters are placed on the front side. Stick it. Photographs and posters can be removed if desired, and the panel itself can be easily removed from the wall.

[Effect of the device]

 As described above, the display panel of the present invention has the following effects by adopting the above configuration. The display panel of the present invention uses an adhesive layer having a removability that does not transfer to the adherend when the adherend is peeled off. , It is possible to change the pasting position even if the pasting position fails. In addition, since the adhesive can be peeled off neatly without sticking the adhesive to the adhered material, and the adhesive layer has an adhesive force even after the peeling, it can be repeatedly used several times. Further, according to the present invention, since the pressure-sensitive adhesive layer is formed on the surface of the plate-shaped core material through the paper, it is difficult for air to be trapped between the pasting material and the paper, and air bubbles and the like like the conventional panel are generated. It has the effect that it is easy to attach paper or film without sticking, and the attachment surface is formed neatly. Moreover, since the paper on both the front and back sides reinforces the plate-shaped core material, warping of the panel can be prevented.

Further, when the pressure-sensitive adhesive layer is formed only on one side, the surface of the plate-shaped core material is not directly exposed on the side opposite to the side on which the pressure-sensitive adhesive layer is formed, and thus a paper sheet is pasted. Like the panel of, the back side is less likely to get dirty due to static electricity. In addition, paper sheets have better printability and writing characteristics than synthetic resin foam, so silk printing or handwriting is possible on the side without the adhesive layer, and both sides are effectively used. can do. In addition, when the display panel of the present invention is manufactured, it can be manufactured by a simple operation of simply adhering the paper on which the adhesive layer is provided in advance to the plate-shaped core material. It has a high effect.
