BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows an embodiment of the decorative panel of the present invention, in which a base material 1, a white layer 2, a phosphorescent layer 3, and an ink receiving layer 4 are laminated in this order from the lower layer for decoration. Panel 5 is configured.

[0029] The white layer is formed of a white pigment by screen printing or the like. Further, when the base material 1 itself is white, it is not necessary to form a white layer.

[0030] The phosphorescent layer 3 is preferably formed as a plurality of layers, that is, the luminous intensity is increased by increasing the film thickness of the phosphorescent layer 3 by, for example, repeatedly applying the phosphorescent agent in three to five times. Improvement and uniformity.

[0031] The ink receiving layer 4 is a layer for fixing a sublimation ink image printed on a medium by an ink jet recording apparatus, and is preferably a transparent material that is easy to dye sublimation ink, such as a polymer. Constructed as a layer of material.

[0032] Next, a phosphorescent agent is laminated on the surface of the white layer 2 by screen printing or the like to form a phosphorescent layer. This operation is preferably performed a plurality of times. By forming the phosphorescent layer as a plurality of layers in this way, the entire surface can emit light uniformly, and the film thickness of the phosphorescent layer can be increased to increase the emission intensity.

[0033] When the formation of the phosphorescent layer 3 is completed, a sublimation ink from the transfer paper image formed with the sublimation ink is easily dyed and a polymer material having good light transmittance is screened.

—The image receiving layer 4 is formed by screen printing or coater printing.

Next, a method for forming an image on the decorative panel 5 configured as described above will be described.

An image is printed on a print medium with an ink jet printer using sublimation ink, the ink surface of the print medium is brought into close contact with the receiving layer 4 of the decorative panel, and the image is formed by heating to a predetermined temperature. The molecules of the photosensitive ink sublimate and dye the ink receiving layer 4, and the image is transferred to the ink receiving layer 4.

Replacement paper (Rule 26) [0035] That is, since the sublimation ink has the property of being vaporized when heated and dyed to rosin, the image data of the manuscript is taken into a computer and appropriately edited with graphic software. It is possible to form an image with high light transmissivity that balances the visibility of the image and the light emission at the place.

[0036] Thus, a desired image can be printed by a general-purpose inkjet printer, and the panel can be printed with a light-transparent high-V, image with a simple method of heating the printed medium in close contact with the panel. Can be formed.

[0037] When the panel to which the image is transferred in this manner is irradiated with light including ultraviolet rays such as sunlight or black light, the phosphorescent layer 3 is excited to emit light. The image formed on the receiving layer 4 is originally formed with sublimation ink, so that it has sufficient light transmission even in the color region, and part of the light in the phosphorescent layer 3 is transmitted, and the applied force also slides. A knocklight is placed on the back of the film! The entire painting is lifted and displayed as if it were scolding.

[0038] By the way, when constructing a large image with such a panel, create a decorative panel with a standard aluminum panel, etc., print the image divided into tiles, and then print each panel into a single panel. Any large-sized panel can be formed by connecting each panel to the wall surface by bonding or screwing.

[0039] In the above-described embodiments, the force of forming an image on transfer paper by an inkjet printer capable of printing image data of a digital camera or the like accurately and inexpensively. Offset printing method, gravure printing method, or screen printing method Can also print sublimation ink on transfer paper, so you can form a transfer image on transfer paper using any of these printing methods.

[0040] FIG. 2 shows a mounting table 13 suitable for the panel of the present invention, which is disposed at one end of the base 10 and a base 10 having a gripping means for fixing the lower region of the decorative panel 5. The light source unit 11 irradiates the front surface of the decorative panel 5 and the power source unit 12 disposed on the back side of the decorative panel and supplying power to the light source unit 11.

[0041] The illuminating unit 11 is preferably provided with diffusing means such as a hood so as to uniformly illuminate the front surface of the decorative panel 5 using black light or an ultraviolet light emitting diode as a light source. [0042] In this embodiment, when the decorative panel 5 is fixed to the mounting portion 13 and irradiated with ultraviolet rays from the illumination portion 11, the phosphorescent layer 3 emits visible light. For this reason, when the surrounding illumination is dark, the visible light from the phosphorescent layer 3 of the decorative panel 5 is transmitted through the ink image of the receiving layer 4, and the image is lifted up.

[0043] Note that, in the above-described embodiment, since the ultraviolet light source such as a black light is arranged at a relatively conspicuous level, the decorative panel is large in size. However, the entire panel surface can be illuminated uniformly.

On the other hand, in the case where the size of the decorative panel is small, the size of the light source is larger than that of the panel, which causes a problem in the placement location. In such a case, a frame-like frame 13 is provided around the panel 5 as shown in FIG. 3 (a), and the reflector 14 and the black plate are provided on the frame 13 as shown in FIG. 3 (b). It is desirable to accommodate a small ultraviolet light source 15 that emits ultraviolet light, such as light and ultraviolet light emitting diodes!

According to this, the partial force of the light from the ultraviolet light source 15 is diffused over the entire surface by the reflecting plate 14 provided in the decorative panel 5, and the entire surface is irradiated as uniformly as possible.

By the way, when used outdoors, weather resistance is particularly required.

Fig. 4 (a) shows an example of a decorative panel suitable for outdoor use. A phosphorescent layer 21 is formed on the surface of a ceramic plate 20 such as a ceramic that can withstand the firing temperature. The image layer 22 is fired and formed at a high temperature of 700 to 1200 ° C. with a fired pigment having excellent weather resistance.

[0047] The phosphorescent layer 21 may be formed by mixing a transparent glaze and a heat-resistant phosphorescent agent, uniformly layering the surface of the ceramic plate 20 by screen printing or the like, and firing at 700 ° C to 1200 ° C. it can

[0048] If the image forming surface side of the ceramic plate 20 constituting the substrate is white, the phosphorescent layer may be formed as it is. However, if it is colored, it is white after firing as shown in Fig. 4 (b). If the white layer 23 is formed using a glaze that becomes, for example, a glaze for white ceramics, an image of the surface of the phosphorescent layer can be displayed with high contrast.

[0049] After forming the phosphorescent layer 21 in this way, an image or pattern is formed on the surface of the phosphorescent layer using ceramic transfer paper and fired together with the ceramic plate 20.

Replacement paper (Rule 26) Such a transfer paper can be easily prepared by forming an image on a medium by an electrostatic printing method using a fired pigment as screen printing, offset printing or a fired pigment toner.

[0050] Since the image layer of the decorative panel configured as described above has excellent light transmittance, the light from the phosphorescent layer is transmitted, and the image is slide-filled in the same manner as in the previous embodiment. The display can be displayed as if it were backlit, and each layer has weather resistance, so it can be used outdoors for a long time.

[0051] In the above-mentioned embodiment, a ceramic plate such as ceramics is used as a substrate that can withstand the firing temperature. However, white glassy material is used as a glaze on the surface of the metal substrate, that is, the metal plate. The same effect can be obtained by using a baked product and forming a phosphorescent layer and an image layer on the surface.
