Abstract

PROBLEM TO BE SOLVED: To enable a photograph to be fixed to a lining material in a state as flat as a mirror easily and securely by an inexperienced person by arranging adhesive layers on both sides of a resin sheet or a paper sheet and fixing a strippable paper to each adhesive layer. SOLUTION: The lining material 1 comprises a base plate 2, a thin resin or paper sheet 3, and the strippable paper 4, and the adhesive layers 5, 6 interposed between the baseplate 2 and the sheet 3 and between the sheet 3 and the strippable paper 4. One side or both sides of the sheet 3 are subjected to roughening treatment, such as sand blast treatment, to form wholly finely rough faces. When the lining material 1 is used, the strippable paper is peeled off a photograph is placed on it and the photograph is pressed from above, and since the excess adhesive is expelled to the inside of the roughed face, trouble caused by that the excess adhesive solidifies here and there and these parts rise and impair the flatness of the whole parts of the photograph can be avoided. When the reverse side of the resin sheet 3 is also roughed, such trouble can be restrained on the reverse side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing material for a photograph, and more particularly, to attach a photograph to a mirror surface, that is, a state where no irregularities are generated on the surface when displaying the photograph in a frame. In addition, the present invention relates to a backing material that secures flatness by preventing warpage and waving of a photograph.

[0002]

2. Description of the Related Art Photographs for display, decoration, etc. may lose their flatness due to wrinkling or waving due to the heat, humidity, temperature change, etc. of the spotlight. As the value of the work decreases, a backing material is established to ensure its flatness.

Conventionally, polyester materials, polyvinyl chloride materials, thick Kent paper, and the like have been used as a backing material for the above photographs. For fixing photos on these backing materials,
A method using double-sided tape or spray paste, which is the simplest method, is often used. This method is still good if the resin part is soft photographic paper in the photograph of the resin coated paper (RC paper), but if it is hard photographic paper, the double-sided tape part is good. In this case, unevenness is generated on the surface of the photograph, the appearance is deteriorated, and the value of the photograph is reduced.

Further, even if the above-mentioned simple method is used, fixing a photograph to a backing material cannot be performed well unless the user is not accustomed to it.

[0005]

As described above, in the prior art, the work of fixing a photograph to a backing material has not been easy, and it has been extremely difficult to simply and reliably apply a mirror surface. It is an object of the present invention to provide a photographic backing material that enables even a person who is not used to easily and surely fix a photograph on a backing material in a mirror surface state.

[0006]

According to the present invention, a first adhesive layer is provided on a synthetic resin or paper substrate, and one or both surfaces are roughened on the first adhesive layer. Backing of a photograph comprising disposing a resin sheet or paper material provided, providing a second adhesive layer on the resin sheet or paper material, and placing a release paper on the second adhesive layer. A material or a resin sheet or paper material having a roughened surface on one or both sides, an adhesive layer disposed on both sides of the resin sheet or the paper material, and a release paper on each of the adhesive layers. The above problem was solved by using a lining material of a photograph in which the image was fixed.

[0007]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an embodiment of a backing material 1 according to the present invention. The backing material 1 comprises a substrate 2, a thin (usually 100 μm or less) resin sheet 3 or paper, and a release paper 4; The adhesive layers 5 and 6 are interposed between the resin sheet 3 and the resin sheet 3 and between the resin sheet 3 and the release paper 4 (the thickness is exaggerated for convenience of explanation). Rough surface processing is performed on one or both surfaces of the resin sheet 3, that is, fine irregularities are formed on the entire surface by sandblasting or the like.

In use, the release paper 4 is peeled off, a photograph is placed, and pressure is applied from above the photograph. At this time, the excess adhesive escapes to the concave portion on the rough surface of the resin sheet 3, so that the excess adhesive is partially solidified, the portion is raised, and the smoothness of the entire photograph is not impaired. When the back surface of the resin sheet 3 is roughened, the same occurs on the back surface.

As the adhesive, a normal tacky adhesive is used. In this case, the pressure from above can be absorbed and dispersed by utilizing its elasticity. That is, since the pressure applied to the adhesive layer 6 from the photograph is first received on the surface of the resin sheet 3 and then transmitted to the adhesive layer 6, the pressure applied to the adhesive layer 6 by the resin sheet 3 is dispersed. . As a result, the pressure applied to the adhesive layer 6 decreases, and the photograph returns to a flat state due to the restoring force of both the adhesive itself and the resin sheet.

[0010] Pressing the photograph from above is performed by a roller.
In this case, when the bonding surfaces are flat surfaces, a portion having high pressure and a portion having low pressure appear, and it is difficult to attach the bonding surface to a flat surface. If the adhesive surface is roughened as described above, the adhesive pressure will be mechanically adjusted because the adhesive will not adhere to the convex part of the rough surface even if the force is always held down without increasing or decreasing the force. In this case, the glue can be glued to a certain thickness in the same manner as in the above case. In addition, no deflection or displacement occurs.

A paper material can be used instead of the resin sheet 3. The paper material used here has a thickness of about ordinary paper or more. In the case of this paper material, since the surface is originally a rough surface, it is not necessary to perform a rough surface processing, and the paper material can be used as it is.

In the second embodiment of the present invention, a release paper 8 is fixed in place of the substrate 2 having the above structure. In this case, the release paper 8 can be peeled off and pressure-bonded to a desired plate or a desired place such as a wall surface. Even in this case,
Since the resin sheet 3 subjected to the roughening is disposed between the adhesive layers 5 and 6, the mirror surface can be applied in the same manner as described above.

[0013]

The present invention is as described above. In the backing material according to the present invention, a resin sheet or paper material having a roughened surface is interposed between the adhesive layers. When pressed and placed, excess adhesive escapes into the recess, so there is no unevenness, so it is possible to apply mirror surface,
Since the handling is easy, there is an effect that even a person who is not accustomed can easily apply the mirror surface.
