CONSTITUTION:A rear plate 1 is made of a fiber reinforced plastic (FRP). A color print photograph 2 formed by printing an appropriate photographic image P on special photographic printing paper has a remarkably small possibility of discoloring and fading and a fastness to light. A photograph surface covering material 3 is made of a transparent synthetic resin, such as an acrylic resin or a polycarbonate resin, having a high strength and a weatherability. These are integrally laminated so that the color print photograph 2 can be perfectly sealed between the rear plate 1 and the photograph surface covering material 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a decorative panel containing a photograph, which is used in the same or similar manner as a color tile, and a method for manufacturing the same.

[Conventional technology]

Conventionally, color tiles with decorative patterns such as flowers are generally known.

[Invention or problem to be solved]

The conventional color tiles described above are made by drawing decorative patterns such as flowers on the surface of the tile base plate, applying a varnish, and firing it. Therefore, it requires skill to draw the decorative pattern and to bake the tiles, and it takes time to manufacture them. This has led to problems such as extremely high product costs, and because fired tiles have low strength and break easily, they cannot be used by laying them on sidewalks or attaching them to manhole covers.

This invention was invented to solve the above-mentioned conventional problems, and its first purpose is to provide beautiful color printed photographs that are excellent in strength, water resistance, and weather resistance, and do not cause problems of discoloration or fading. A second object of the present invention is to provide a method for manufacturing a decorative panel with a photograph, which allows the decorative panel to be manufactured easily and inexpensively without requiring special skill. .

[Means to solve the problem]

In order to achieve the first object, the decorative panel of the present invention has a back plate 1 made of reinforced plastic, and a suitable photographic image P printed on special photographic paper to ensure light fastness with extremely little discoloration or fading. The color printed photograph 2 is placed between the back plate 1 and the photographic surface covering material 3, and the photographic surface covering material 3 is made of strong and weather-resistant transparent synthetic resin. It is laminated to be completely sealed.

In addition, in order to achieve the second object, the method for manufacturing a decorative panel of the present invention includes applying a release agent 6 on a base plate 4 having a smooth surface.
A release agent coating step of applying a weather-resistant transparent synthetic resin on the upper surface of the release agent 6 applied to the surface of the base plate 4 and the image side surface of the color print photograph 2 is formed. Applying gel-like resins 3a and 3b for the photo pasting, turning the photo 2 over, and pasting the photo so that the photo coating resin 3b and the base plate coating resin 3a adhere to each other. A reinforced plastic back plate 1 is attached to the upper surface side, which is the back surface, with the intervention of reinforcing material a and gel-like resin 1a, lb...
After at least four steps: a back plate forming step in which the back plate is formed by coating several times, and a panel separation step in which the decorative plate 7 containing the photograph and the base plate 4 are peeled off from the part of the release agent 6 after the back plate is formed. The present invention is designed to manufacture a decorative panel of the size of a photobook as described above.

[Effect]

In the decorative panel having the above structure, the back plate 1, which is the backing material for the color print photo 2, is made of strong reinforced plastic (FRP), so it has superior strength and is less likely to break compared to conventional fired tiles. Therefore, problems such as panel cracking will not occur even if this decorative panel with photographs is used by laying it on a sidewalk or attaching it to a manhole cover.

In addition, the decorative panel containing this photograph is a color print photograph 2, which has an appropriate photographic image printed on special photographic paper and has extremely light fastness with minimal discoloration and fading, and the surface of this photograph is weather resistant. Since the surface covering material 3 is made of a strong transparent synthetic resin and is completely sealed, it has excellent water resistance and weather resistance, and does not cause the problem of discoloration and fading as in the photograph 2.

Further, according to the method for manufacturing a decorative panel of the present invention, a decorative panel with a beautiful color photograph, which has the characteristics described above, can be easily manufactured without requiring any special skill, and can be provided at a low cost.

〔Example〕

Hereinafter, the structure of a decorative panel according to an embodiment of the present invention will be explained as follows.
To explain according to the drawings shown in Fig. 2 and Fig. 2, this decorative panel has a back plate 1 made of reinforced plastic (FRP) and an appropriate photographic image P printed on special photographic paper, which has extremely low light fastness and no discoloration or fading. A photographic surface covering material made of a color printed photograph 2 (for example, using the product name "Fujichrome CB Print" of Fuji Color Service Co., Ltd.) and a strong and weather-resistant transparent synthetic resin, such as acrylic resin or polycarbonate resin. 3 are laminated and integrated so that the color printed photograph 2 is completely sealed between the back plate 1 and the photographic surface covering material 3,
It is manufactured by the following manufacturing method.

As the first step, a base plate 4 made of a glass plate with a smooth surface
is placed on the work table 5, the upper surface (surface) of this base plate 4 is thoroughly cleaned, and a third mold release agent 6 is applied to the surface of this base plate.
Apply as shown in the figure (mold release agent application process).

As a second step, a gel-like resin is applied to form a weather-resistant transparent synthetic resin photographic surface coating material 3 on the upper surface of the release agent 6 applied to the surface of the base plate 4 and on the image side surface of the color print photograph 2. 3a and 3b (for example, gel-like transparent acrylic resin) are applied using a rotating roller (not shown) as shown in FIG. 4, and the photo 2 is turned over so that the photo coating resin 3b and the base plate coating resin 3a adhere Apply pressure and paste the photo as shown in Figure 5 (photo pasting is a process).

As a third step, a reinforced plastic back plate is formed on the upper surface side of the photographic paper 2, which is the back surface, by intervening a reinforcing material and applying several coats of gel-like resin. That is,
The process of forming this back plate 1 is to first apply a gel-like resin 1a such as epoxy resin or phenol resin to a sixth layer using a rotating roller or the like.
Apply the resin as shown in the figure, place a reinforcing material a made of glass fiber thin cloth on top of it, and then apply a gel-like resin 1b, which is the same as the resin 1a, on the reinforcing material a as shown in FIG. Thereafter, the same operation is repeated several times, for example, 3 to 4 times, and finally the back surface is coated as shown in FIG. 8 to form the back plate 1 of reinforced plastic.

As a fourth step, after the formation of the back plate 1, a decorative plate 7 containing a photo, in which the back plate 1, the photo 2, and the photo surface covering material 3 are laminated and integrated, is removed from the part of the release agent 6 of the base plate 4. Panel separation is performed by peeling off as shown in the figure, and as a final finishing step, the peripheral edge of the decorative plate 7 after separation of the base plate is neatly cut with a cutter (not shown), and the photographs shown in Figures 1 and 2 are obtained. Manufactures enclosed decorative panels.
