Description

[Technical Field]

[0001] The present invention relates to a backing material and backing method for photographs and other works, and more specifically to a backing material and backing method for photographs and other works that are less likely to warp and can keep photographs and other works smoothly attached for a long period of time. [Background technology]

[0002] Photographs, paintings, and other artworks intended for exhibition or decoration are generally attached to a backing material to prevent the heat of spotlights, humidity, temperature changes, etc. from causing them to wrinkle or ripple, losing their smoothness and reducing the value of the artwork.

[0003] The backing material has an adhesive layer covered with a release sheet on one side, and when attaching a photograph, the release sheet is removed to expose the adhesive layer, and the photograph is then attached onto it. Because the photograph is attached to one side of the backing material, and it is not intended to be attached to both sides, the adhesive layer and release sheet are only located on one side of the backing material. This creates a tension difference between the front and back of the backing material, which can cause warping and loss of smoothness. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-90855 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made to solve the problems of the above-mentioned conventional backing materials, and its objective is to provide a backing material for photographs and other works that is resistant to warping and can maintain smoothness by balancing the tension on the front and back surfaces of the base sheet, and a method for backing photographs and other works using the same. [Means for solving the problem]

[0006] The invention described in claim 1 for solving the above problem is a base sheet having adhesive layers on both the front and back sides thereof, and a release film covering each of the adhesive layers. The release film is release-treated on only one side, and after being peeled off, the film can be turned over and the non-release-treated side can be permanently adhered to the adhesive layer. The thickness and hardness of the release film applied to one side of the base sheet are different from those of the release film applied to the other side. This is a backing material for photographs and other artworks.

[0007] The invention described in claim 2 to solve the above problem is a backing material for photographs and other artworks, which is made by providing adhesive layers on both the front and back of a base sheet, and covering each adhesive layer with a release film, and the release film is release-treated on only one side, so that after it is peeled off, it can be turned over and the non-release-treated side can be permanently adhered to the adhesive layer, and the base sheet has holes of an appropriate shape. .

[0008] In one embodiment, the adhesive layers are provided partially on both the front and back surfaces of the base sheet. [Effects of the Invention]

[0010] The backing material for photographs and other works of art according to the present invention is as described above, and by covering both the front and back of the base sheet with release films, the tension on the front and back of the base sheet is balanced, resulting in a backing material that is less likely to warp and can maintain its smoothness.Furthermore, when a photograph is adhered to only one side, the release film on the back can be turned over and the side that has not been released can be adhered to the adhesive layer, which has the effect of maintaining the balance of tension on the front and back of the base sheet for a long period of time.A backing method using this has the effect of maintaining the flatness of the work for a long period of time.

DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described with reference to the accompanying drawings. The backing material 11 for photographs and other artworks according to the present invention is used to support artworks 10 such as photographs and paintings for display or display. It comprises an adhesive layer 2 on both sides of a base sheet 1, and release films 3 and 4 applied thereon. In the backing material according to the present invention, the release films 3 and 4 are applied to both sides of the base sheet 1 in this manner in order to balance the tension between the front and back surfaces of the base sheet 1 and prevent warping of the base sheet 1.

[0013] It is recommended to use Yupo, manufactured by Yupo Corporation, as the base sheet 1. Yupo is a synthetic paper made primarily from polypropylene and a natural mineral inorganic filler, and has properties such as excellent water resistance, tear resistance, resistance to oil and chemicals, light weight, and a smooth surface. Furthermore, it is preferable to use a release film, in which a polyester film has been subjected to a release treatment, as the release films 3 and 4. The release films 3 and 4 are subjected to a release treatment on only one side. As described below, the release films 3 and 4 are intended to be peeled off, then turned over and re-adhered onto the adhesive layer 2.

[0014] The release films 3 and 4 may have the same thickness, hardness (elasticity), or color, but may also be different. For example, if it is intended that a photograph will be attached to only one side, the release film 5 on the back side should be relatively thick (50 to 100 microns) and have high hardness (low elasticity), while the release film 3 on the front side where the photograph will be attached should be thinner. This is done to balance the tension between the front and back of the base sheet 1 and prevent warping of the base sheet 1. Note that the product is available in single-sided and double-sided adhesive versions, and for the single-sided adhesive version, the side to which the artwork 10 will be attached is specified.

[0015] The artwork 10, such as a photograph, adheres to the adhesive layer 2 exposed by peeling off the release films 4, 5, but once adhered, it may be necessary to reattach or replace it. In this case, if the adhesive layer 2 is provided on the entire front and back of the base sheet 1, the adhesive strength may be too strong, making it difficult to peel off the artwork 10 and possibly damaging the artwork 10. Therefore, to weaken the adhesive strength, holes 5 of an appropriate shape may be provided in the base sheet (Fig. 4), or the adhesive layer 2 may be provided partially (Fig. 5).

[0016] FIG. 4 shows examples of through-holes 5. (A) shows an example in which circular through-holes 5 are arranged regularly in the vertical and horizontal directions, and (B) shows an example in which oblong rectangular through-holes 5 are arranged regularly in the vertical and horizontal directions. (C) shows an example in which trapezoidal and rectangular through-holes 5 are arranged diagonally. The shape of the through-holes 5 is not limited to these examples and can be any shape, and their arrangement does not need to be regular. FIG. 5 also shows examples of when the adhesive layer 2 is partially arranged. In the example shown in (A), a large square along the periphery of the base sheet 1 and small squares arranged inside it are used as the adhesive layer 2. In the example shown in (B), a large square along the periphery of the base sheet 1 and rectangular parts arranged at equal intervals inside it are used as the adhesive layer 2. The adhesive layer 2 may be arranged randomly, but it is preferable that at least the large squares along the periphery of the base sheet 1 are used as the adhesive layer 2.

[0017] The method for backing a work such as a photograph according to the present invention uses the above-mentioned backing material 11 and comprises the steps of preparing the backing material 11 and peeling off the release films 3, 4 and adhering the work 10 such as a photograph to the adhesive layer 2. The step of preparing the backing material 11 includes the step of selecting a backing material 11 covered with release films 3, 4 having a thickness (stretchability) corresponding to the thickness (stretchability) of the work 10 such as a photograph. For this purpose, a plurality of types of products corresponding to the thickness and size of the work 10, i.e., a plurality of types of products (backing materials 11) having different thicknesses and strengths of the base sheet 1 and release films 3, 4, are prepared as the backing material 11 according to the present invention.

[0018] In the process of adhering the work 10, one of the release films 3 and 4 is peeled off, the work 10 is placed on the exposed adhesive layer 2, and the work 10 is adhered to the backing material 11 by lightly pressing it down with a roll (Fig. 2). In this way, the work 10 can be easily adhered to the backing material 11, and its smoothness is maintained throughout the exhibition period.

[0019] Furthermore, when artwork 10 is adhered to only one side of base sheet 1, a process is included in which release film 4 on the non-adhesive side of artwork 10 is temporarily peeled off, turned over, and placed on adhesive layer 2 (Fig. 3). In this way, when artwork 10 is attached to one side, release film 4 on the non-adhesive side of artwork 10 is turned over and reattached in order to strengthen the adhesion of release film 4 to adhesive layer 2 by attaching the non-release-treated side of release film 4 to adhesive layer 2, thereby increasing tension by preventing release film 4 from peeling off over the long term, and maintaining a balance of tension on both the front and back sides to prevent warping.

[0020] In addition, once a photograph or other artwork 10 has been adhered, it may need to be peeled off from the adhesive layer 2 in order to be re-pasted or replaced. In this case, if the base sheet 1 has holes 5 (Figure 4) or the adhesive layer 2 is partially provided, the adhesive strength is weakened to an appropriate degree, allowing the artwork 10 to be easily peeled off from the adhesive layer 2 without any risk of damaging the artwork 10.

[0021] Artwork 10 backed with this backing material 11 can be framed in any manner. Figure 6 shows an example of framing art 10 adhered to only one side of base sheet 1, with release film 4 on the non-adhesive side reversed and placed on adhesive layer 2. In this case, if back cover 13 of frame 12 is a wooden or plastic board, the back side of art 10, i.e., the side where release film 4 has been reversed and re-applied on adhesive layer 2, is attached to back cover 13 using, for example, double-sided tape. If necessary, a mat 14 with a window is then attached and fixed on top of art 10, also using double-sided tape (Figure 6(A)). Alternatively, if back cover 13 is a metal plate, a magnetic sheet with single-sided adhesive is adhered to the back side of art 10 to magnetically attach art 10 to back cover 13, and then a mat 14 with a magnetic sheet adhered to its back side is attached to art 10.

[0022] Artwork 10 backed with this backing material 11 may also be fixed to an exhibition panel 15. In this case, the sizes of artwork 10 and panel 15 are adjusted to match, and artwork 10 is fixed snugly over the entire surface 16 of panel 15 so that it does not protrude beyond the panel 15 (Fig. 7(A)). As with the framing described above, double-sided tape or the like is used to fix artwork 10 to the panel if the surface 16 is made of wood or resin, and a magnetic sheet is used if the surface 16 is made of metal. [Industrial Applicability]

[0023] The backing material for photographs and other works of the present invention is as described above, and by covering both the front and back of the base sheet with release films, the tension on the front and back of the base sheet is balanced, resulting in a backing material that is less likely to warp and can maintain its smoothness.Furthermore, when a photograph is adhered to only one side, by flipping the release film on the back and adhering the side that has not been released to the adhesive layer, the balance of tension on the front and back of the base sheet can be maintained for a long period of time.A backing method using this has the effect of maintaining the flatness of the work for a long period of time, and therefore has great industrial applicability.
