Description

  The present invention relates to a display sheet in which an image surface of a sheet-like display can be observed through the transparent material by pasting and displaying the sheet-like display facing a transparent material such as glass.

  By sticking a sheet-like exhibit from the inside to the glass surface of a store, etc., the image surface of the sheet-like exhibit can be observed from the outside through the glass, and the glass surface can be used as an exhibition space. It has been broken. Conventionally, double-sided adhesive sheets, adhesives, and the like have been used for attaching such sheet-like exhibits. However, when a sheet-like exhibit is pasted with a double-sided adhesive sheet or adhesive, the image may become unsightly due to incomplete contact with the transparent material such as glass and air bubbles remaining, or when the image is peeled off. Adhesives and adhesives remained on the transparent material surface, which sometimes caused problems.

  In order to solve these problems, an exhibition sheet has been proposed in which adhesives are provided on both sides of a transparent sheet in the form of dots or blocks (see Patent Document 1). However, although the adhesion to the transparent material is improved by this display sheet, depending on the material of the transparent material, such as when the transparent material is plastic, the adhesive may still remain on the transparent material side at the time of peeling. .

On the other hand, as a sheet-like exhibit, a recording in which a porous ink absorption layer comprising a pigment such as amorphous silica or alumina and a water-soluble binder such as polyvinyl alcohol is provided on a sheet-like support called an inkjet recording sheet A material that has been image-recorded by a printer using an inkjet recording method is often used. An ink jet recording sheet having such a porous ink absorbing layer is very excellent in ink absorbability, but it is easy to cause discoloration in a printed image after printing due to the influence of a minute amount of gas in the atmosphere, etc. Have a problem. Even when a sheet-like display using an ink jet recording sheet is pasted to face a transparent material such as glass, discoloration of the printed image due to fading is a problem, and improvement has been desired.
Japanese Utility Model Publication No. 5-51936

  Therefore, the purpose of the present invention is to improve the workability at the time of pasting and peeling, and to prevent discoloration due to the fading of the image when a sheet-like display is pasted and displayed facing a transparent material such as glass. It is to provide an exhibition sheet that can be used.

  An exhibition sheet for attaching an image surface of a sheet-like exhibit according to the present invention to a transparent material such as glass has a continuous transparent adhesive layer on one side (A surface) of a transparent resin film. In addition, a transparent adhesive layer that is discretely provided by patterning in the form of dots or blocks is provided on the opposite surface (B surface), and a protective sheet is releasably attached to each adhesive layer. It is a characteristic display sheet.

  With the exhibition sheet according to the present invention, when a sheet-like display is pasted and displayed facing a transparent material such as glass, workability at the time of pasting or peeling is good, and discoloration due to fading of the image is prevented. can do.

  Embodiments of the present invention will be described below in detail with reference to the drawings, but the present invention is not limited to the illustrated embodiments.

  FIG. 1 is a schematic cross-sectional view of an embodiment of an exhibition sheet according to the present invention. The display sheet according to the present invention has a transparent adhesive layer 2 continuous on one side (A side) of a transparent resin film 1, and is discretely patterned in the form of dots or blocks on the opposite side (B side). A transparent adhesive layer 3 is provided, and a protective sheet 4 is detachably attached to each adhesive layer, thereby preventing a decrease in adhesiveness due to adhesion of dust or the like to the adhesive layer.

  The material of the transparent resin film 1 may be any material as long as it is transparent and can be coated with an adhesive layer on both sides. For example, a polyester resin such as polyethylene terephthalate (PET) or polyethylene naphthalate, Cellulose ester resins such as acetate resin, triacetate resin, nitrocellulose, cellulose acetate, polyolefin resin, acrylic resin, polycarbonate resin, polyvinyl chloride, polyimide resin, polysulfone, polyphenylene oxide, cellophane, celluloid, etc. . In particular, a polyester resin film is preferably used. The thickness of the resin film is preferably about 50 to 500 μm. The surface of the resin film may be subjected to a surface treatment such as a corona discharge treatment or an easy adhesion treatment by providing a resin layer in order to improve the adhesion with the pressure-sensitive adhesive layer.

  The continuous transparent adhesive layer 2 provided on one surface (A surface) of the transparent resin film 1 is a continuous layer over the entire surface of the A surface, and is an entire surface coating that does not have a portion not coated with an adhesive. Although it is preferably a work layer, an independent non-coating part may be present in the adhesive-coated part.

The transparent pressure-sensitive adhesive layer 3 provided on the surface (surface B) opposite to the surface on which the transparent pressure-sensitive adhesive layer 2 is applied of the transparent resin film 1 is coated with an independent dot-like or block-like pressure-sensitive adhesive over the entire surface of the surface B. The parts are provided in a discrete manner, and the part where the adhesive is not applied is continuous over the entire B surface. The point- or block-like adhesive-coated portion has an area of 1 to 20 mm ² per piece, and the area ratio of the coated portion on the B surface is preferably 5 to 80%, and is uniformly distributed. Preferably it is.

  The pressure-sensitive adhesive used for the transparent pressure-sensitive adhesive layer 2 or 3 only needs to be transparent. In addition to natural pressure-sensitive adhesives such as rosin, natural rubber, and polysaccharides, synthetics such as acrylic, urethane, synthetic rubber, and olefin A resin-based pressure-sensitive adhesive can be used. What is necessary is just to adjust the adhesiveness of an adhesive suitably from a response | compatibility with a to-be-adhered thing. In particular, when the adhesive used for the transparent adhesive layer 3 is attached to a transparent material by using an ultraviolet curable adhesive ink composed of a photosensitive resin, a photosensitive monomer, a photopolymerization initiator, and the like. The transparent adhesive layer 3 can be prevented from remaining on the transparent material side at the time of peeling regardless of the material of the transparent material, and it is preferable because workability is improved, such as a decrease in adhesiveness is reduced even when repeated peeling is performed. . Examples of the ultraviolet curable adhesive ink include JELCON USL series (manufactured by Jujo Chemical Co., Ltd.).

  Air knife coater, blade coater, bar coater, roll coater, slot nozzle, slot die, screen printing machine, flexographic printing machine, gravure coater, offset gravure coater, hot melt wheel, spiral spray The selection may be appropriately made according to the application, such as the type and the coating amount of the pressure-sensitive adhesive, the necessity to give a pattern to the pressure-sensitive adhesive to be coated, and the like. In particular, when an ultraviolet curable adhesive ink is used as the adhesive used for the transparent adhesive layer 3, it is preferably provided by patterning by screen printing, and after coating, it is preferably irradiated with ultraviolet rays and cured. As for the dry film thickness of the transparent adhesive layer 2 or 3, 1-30 micrometers is preferable.

  The protective sheet 4 may be transparent or opaque, and it is preferable to use a sheet or film that has been subjected to a treatment that is easy to peel off by applying a release agent. Since the re-peelability is good, the protective sheet to be attached to the transparent pressure-sensitive adhesive layer 3 side does not have to be subjected to a treatment that facilitates peeling.

  Next, the display method of the sheet-like display using the display sheet according to the present invention will be described. FIG. 2 is a schematic cross-sectional view when a sheet-like display is attached to a transparent material for display using an embodiment of the display sheet according to the present invention. Reference numeral 5 denotes a transparent material such as glass, and reference numeral 6 denotes a sheet-like exhibit in which the image 7 is recorded on the image recording surface.

  The image recording surface side of the sheet-like exhibit is attached to the transparent adhesive layer 2 from which the protective sheet 4 has been peeled off. Since the transparent pressure-sensitive adhesive layer 2 is continuous, the image 7 does not come into contact with the atmosphere once the sheet-like exhibit is pasted. As sheet-like exhibits, various printed materials such as hand-drawn illustrations and posters, silver salt photographs, sublimation thermal transfer images, thermal recording images, etc., recorded on the sheet-like image recording material by various image recording methods should be used. However, it is particularly preferable to use an ink jet recording sheet on which an image is recorded by an ink jet printer because discoloration of a printed image due to fading can be prevented. An ink jet recording sheet used as a sheet-like exhibit is a recording material in which a porous ink absorbing layer comprising a pigment such as amorphous silica or alumina and a water-soluble binder such as polyvinyl alcohol is provided on a sheet-like support. And the effect of this invention is more remarkable. The size of the display sheet according to the present invention is preferably the same as or larger than the size of the sheet-like display.

  Subsequently, the protective sheet 4 on the transparent pressure-sensitive adhesive layer 3 side is peeled off and attached to a transparent material, and the image surface of the sheet-like display is displayed facing the transparent material. In this way, the image can be viewed through the transparent material.

  Since the transparent pressure-sensitive adhesive layer 3 is discretely provided in a pattern of dots or blocks, bubbles and the like do not remain between the transparent material and the image does not become unsightly. Moreover, since the re-peelability is good because it is patterned in a dot shape or a block shape and is provided discretely, it can be easily peeled off or the sticking position can be changed as necessary. In particular, when an ultraviolet curable adhesive ink is used as the adhesive, the adhesive property between the transparent adhesive layer 3 and the resin film 1 is improved, and the adhesive durability is also improved. Even when attached to the material, the transparent adhesive layer 3 can be prevented from remaining on the transparent material side at the time of peeling, and even when sticking and peeling is repeated, there is little decrease in adhesiveness and workability is good.

  The exhibition sheet according to the present invention has an excellent effect when used in the above-described display method, but is not limited to the above-described display method, and can be used in various display methods.

  For example, when a sheet-like display is exchanged as necessary without changing the display position on the transparent material, the transparent adhesive layer 2 is attached to the transparent material and the sheet-like display is displayed on the transparent adhesive layer 3 The image recording surface side of the object may be attached. In this case, it is necessary to attach the transparent pressure-sensitive adhesive layer 2 so that no bubbles or the like remain between the transparent material and an image is recorded on an ink jet recording sheet as an exhibition sheet. However, since the releasability of the transparent pressure-sensitive adhesive layer 3 is good, even an ink jet recording sheet having a porous ink absorbing layer with low coating layer strength can be used. It can be easily replaced and is suitable for exhibitions that can be replaced in a short period of time.

  In addition, when displaying sheet-like exhibits on walls, etc., the display sheet according to the present invention can be attached to a normal double-sided adhesive sheet by sticking the surface of the sheet-like exhibit on which no image is recorded to the adhesive layer. Can be used similarly. Even in this case, when the side to be adhered to the adherend such as the wall is the transparent adhesive layer 3, since the removability is good, it is possible to easily peel off or change the affixing position as necessary, It is possible to prevent the transparent pressure-sensitive adhesive layer 3 from remaining on the adherend side at the time of peeling, and even when the sticking and peeling are repeated, there is little decrease in pressure-sensitive adhesiveness and workability is good. Furthermore, if the side to be attached to the adherend is the transparent adhesive layer 2, the sheet-like display can be easily exchanged and displayed as required without changing the display position. The sheet exhibits an excellent effect that cannot be obtained with a normal double-sided adhesive sheet.
