DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a mural using printing paper for murals, and is particularly used as an exhibition material in museums and art galleries, as a building material for large stores and indoors, and as a display material. Related to what is offered to

[Background of the Invention and Problems to be Solved by the Invention] With the improvement of the printing technology, in the field of art reproduction printing, a printing / processing technology that reproduces exactly the same irregularities as the original image and the matiere of the original image as it is. By selecting and printing a material close to the material of the original image, it is possible to reproduce not only colors but also the feel of the original image. Under such circumstances, recently, an attempt has been made to enlarge an original image as a display and produce a large mural by a printing technique.

However, when a plurality of divided printing papers are pasted up, down, left, and right to produce a large mural in particular, it is important to maintain smoothness and to suppress occurrence of displacement due to expansion and contraction.

The present invention has been made in view of such problems, and an object of the present invention is to provide a printing paper for murals having an appropriate elasticity required for construction and having sufficient strength and durability as a mural. It is to provide a mural using.

[Means for Solving the Problems] In order to achieve the above object, a mural using the printing paper for mural painting of the present invention is prepared by bonding a Japanese paper on the back surface of a resin-impregnated paper having a printing layer on the front surface with an adhesive. Is divided into a plurality of mural printing papers, and the divided plurality of mural printing papers are laminated on a wall surface via a mural base. In particular, the mural base is composed of a first floating layer in which a plurality of Japanese papers are vertically and horizontally adjacent to each other via an adhesive on the wall surface so that the ends thereof are superimposed, and a first floating layer. On top of the first floating layer, the Japanese paper is
The configuration including the second floating adhesive layer stacked by shifting by pitch is a preferable embodiment.

Further, when a plurality of divided mural printing papers are pasted and laminated, it is also preferable to adopt a configuration in which the paper is laminated sequentially from the top to the ground in the vertical direction and from the center to the horizontal direction in the horizontal direction. It is an aspect.

Such a mural printing paper of the present invention has a printing layer on the surface of the resin-impregnated paper, and is made by laminating Japanese paper via an adhesive on the back surface, so that the strength of the resin-impregnated paper and the Japanese paper Due to its uniform and moderate elasticity, it has the appropriate elasticity required for construction and has sufficient strength and durability as a mural.

In the mural painting of the present invention, the printing paper for mural painting of the present invention is used, and is laminated on the wall surface via the foundation for mural painting. In the case of matching, due to the moderate elasticity of the printing paper, flexibility in registering the paper on both sides is improved, and workability at the time of construction is improved. In addition, a crack due to a crack or expansion and contraction of the wall surface can be released by the mural base, so that the influence is prevented from directly appearing on the surface of the mural. Furthermore, when a plurality of divided printing papers are pasted together, they can be stuck from the top to the ground in the top-to-bottom direction so that the shadow of the seam is not seen by the viewer, and the center in the left-right direction. By sticking together in the left and right direction, the displacement due to expansion and contraction can be symmetrically escaped.

 Hereinafter, the present invention will be described in detail.

FIG. 1 is a sectional view showing the structure of the mural printing paper of the present invention.

Examples of the resin-impregnated paper 2 used for the mural printing paper 1 of the present invention include acrylic resin-impregnated paper, and the like, provided that it has elasticity and is excellent in strength, durability, and printing characteristics. The material is not particularly limited. A specific example is an acrylic resin-impregnated paper “FX 101-AP (pulp 53
%, Acrylic resin 30%, titanium dioxide 7%, other 10
%) "(Produced by Kojin Co., Ltd.).

The printing layer 3 on the surface of the resin-impregnated paper 2 is formed by an arbitrary printing method, and the ink used is designed in consideration of durability and the like.
In particular, a lightfast ink is desirable.

A Japanese paper 5 is laminated on the back surface of the resin-impregnated paper 2 via an adhesive 4 such as an industrial starch paste. The Japanese paper used is not particularly limited, but for example, Mino paper (handmade Japanese paper) is suitable in terms of smoothness and whiteness.

The adhesive 4 is preferably a mixture of an industrial starch paste and a vinyl acetate adhesive, which satisfies the adhesive strength of the adhesive and easily adjusts the expansion and contraction of the printing paper.

The printing paper for murals according to the present invention is thus a resin-impregnated paper 2
Is subjected to desired printing on the surface thereof, and as a backing, Japanese paper 5 is laminated using an adhesive 4, and the mural printing paper according to the present invention is laminated on the wall via a mural base, thereby forming a wall surface. Is created. The present invention is particularly suitable for creating a large mural by attaching a plurality of divided mural printing papers.

 As an example of the concrete construction process of the mural creation, (1) Filling the joints of the wall panel (2) Filling the joints of the wall panel (3) Pasting the base (4) Registering the registration line on the base (5) Construction.

The steps (1) and (2) are performed to smooth the joints of the wall panel.

In the present invention, it is particularly preferable that the undercoating of the above (3) is affixing using Japanese paper. Specifically, a plurality of Japanese papers are vertically laminated on the wall panel via an adhesive so that the ends thereof are superposed on each other to form a first floating layer,
A second floating layer is formed by laminating Japanese paper on the first floating layer via an adhesive with a shift of 1/10 to 1/2 pitch from the first floating layer. FIG. 2 (a) shows the state of the first floating bonding (first floating layer), and FIG. 2 (b) shows the state of the second floating bonding (second floating layer).
3 is a cross-sectional view of these layers. In the figure, 6 is a wall panel, 7a is Japanese paper forming a first floating layer, 7b is Japanese paper forming a second floating layer, and 8 is an adhesive such as industrial starch paste.

By applying such a base, it is possible to prevent a crack due to a wall surface or a displacement due to expansion and contraction from being released on the base, and to prevent the influence from appearing directly on the surface of the wall surface.
Further, the floating bonding is performed twice, and the first floating bonding and the second floating bonding are performed.
By shifting the floating paste by 1/10 to 1/2 pitch, the seam does not come to the same place to keep the whole smoothness, and the effect of the base can be fully exhibited.

The paper used for the base is not particularly limited, but for example, Sekishu paper (handmade Japanese paper) is used because of its strength, thickness, color close to that of wood, and low cost. Appropriate.

After a black line is drawn as a registration line on such a base paste, a plurality of divided mural printing papers are pasted up, down, left, and right in order while aligning with the registration line, and a mural according to the present invention is created. . FIG. 4 is a cross-sectional view showing a state in which the mural printing paper 1 of the present invention is adhered via an adhesive 9 (for example, an industrial starch paste or the like) on a base as described above. In the drawing, reference numeral 10 denotes a putty for filling the joint of the wall panel 6. As described above, the printing paper for murals of the present invention has a moderate elasticity, and can be stretched in any direction by pulling, so that it is flexible in registering the paper on both sides at the time of construction and the laminating work is performed. It's easy to do. Also, when a plurality of mural printing papers are pasted together, in the top-to-bottom direction, if they are pasted from top to bottom as shown in FIG. 5, it is possible to prevent the viewer from seeing the shadow of the seam. In the left and right direction, as shown in FIG. 6, it is preferable that the displacement due to expansion and contraction can be symmetrically released by bonding in the left and right direction from the center. Furthermore, as a method of pasting the whole, there is a method of pasting the center vertically first and then spreading it to the left and right, and a method of pasting the upper end first from the center to the left and right, and then pasting it downward.
This differs depending on the design of the mural, etc., and cannot be unambiguously determined. However, it is generally preferable to stick the center vertically, as shown in FIG. In FIGS. 5 to 7, reference numerals indicate the order of attachment.

[Examples] Hereinafter, specific examples of the present invention will be described.

Paste 200 surfaces with a size of 800 mm x 650 mm per surface, and as a whole
A mural measuring 4.0m x 26.0m was created. The printing paper uses acrylic resin-impregnated paper FX 101-AP (Kojin Co., Ltd., basis weight 78 g / m ² ), shades the original, enlarges the plate, and prints the original pattern using the offset method. Done. The printing ink used was a resistant ink containing a resistant pigment, and was subjected to predetermined embossing. The backing of the printing paper uses Mino paper (handmade Japanese paper) medium thickness mouth, and uses a mixture of industrial starch paste (material: wheat starch and processed starch) with vinyl acetate adhesive as an adhesive. I did it.

On the other hand, putty was buried in the seam of the wall panel (plywood) to smooth it, and a 30 cm x 30 cm thick sheet of Sekishu paper (handmade Japanese paper) was floated twice on this panel to adjust the groundwork. .

Next, a registration line is allocated to the dimensions of the panel on the base paste, and 200 printing papers are placed on five sides and 40 sides in the order shown in FIG. They were sequentially laminated.

The completed wall had no displacement due to expansion and contraction of paper and panels, etc., and had moisture resistance and light resistance.

[Effects of the Invention] As described in detail above, according to the mural printing paper of the present invention, a printing layer is laminated on the surface of the resin-impregnated paper, and Japanese paper is laminated on the back, respectively. It is possible to have both the appropriate stretchability and the sufficient strength and durability required for a mural.

Further, in the mural using the mural printing paper of the present invention, since the printing paper has a moderate elasticity, when a large number of murals are created by laminating a plurality of divided printing papers vertically and horizontally. Therefore, flexibility in registering the paper on both sides is improved, and workability at the time of construction is improved. Therefore, even a large mural can be easily created. In addition, since the displacement due to the expansion and contraction of the wall panel and the paper can be escaped by the wall base, it is possible to prevent the influence from directly appearing on the surface of the mural, and the mural has excellent moisture resistance.

Furthermore, when a plurality of divided printing papers are pasted together, they can be stuck from the top to the ground in the top-to-bottom direction so that the shadow of the seam is not seen by the viewer, and the center in the left-right direction. By sticking together in the left and right direction, the displacement due to expansion and contraction can be symmetrically escaped.
