The luminous plate A of the present invention is formed by applying an inorganic luminous material and a glaze to the surface of a base material and baking at a temperature at which the glaze melts. The base material may be any material that does not break under a temperature environment in which the glaze applied to the surface of the base material melts, such as a glazed tile (hereinafter simply referred to as a tile), an unglazed tile, a basin,
Inorganic products such as toilets, glass plates, gypsum boards, and cement products, various metal products, and resin products. In addition, among the above products, inorganic products, metal products, especially inorganic products are preferable because they are more compatible with glazes than resin products. Further, the substrate may be a powder compact.

The luminous material used to form the luminous plate A of the present invention is in the form of a fine powder by itself, and has a luminous characteristic upon receiving ultraviolet energy such as sunlight, fluorescent light, incandescent light or the like. And emits visible light as afterglow for a long time, and this afterglow serves as display light for darkness. The phosphorescent material has a feature that the initial luminance is very high and the luminance decay with time is slow, and the resistance to ultraviolet rays of sunlight is excellent.
It can be used outdoors, from as low as -35 ° C to 750 ° C
The light emitting function hardly changes even under the condition up to the high temperature, and the crystal is extremely stable chemically. Therefore, under ideal conditions, the light storing function and the light emitting function can be maintained semipermanently. In addition, since the light emitting function of the phosphorescent material hardly changes even under a high temperature condition up to 750 ° C., it can be fired together with the glaze. Further, since the light-storing material emits light by the mechanism of the crystal itself, it is safer than a light-storing material using a radioactive substance.

In FIG. 1, FIG. 2 and FIG. 3, the phosphorescent plate A of the present invention is obtained by mixing 2 to 10 parts by weight of the phosphorescent material and 10 parts by weight of a glaze material such as frit into a paste.
The paste is formed by transferring the paste onto the tile 1 as a base material by silk screen printing and firing at 750 ° C. Also, 2 to 10 parts by weight of the phosphorescent material and 10 parts by weight of a glaze material such as frit are mixed to form a paste, and the paste is transferred to an unglazed tile by silk screen printing, and then heated to 750 ° C. It is also possible to form the phosphorescent plate A by firing. In addition, even if the baking temperature is set to 800 ° C.,
Although the phosphorescent performance is inferior to that fired at 0 ° C., it can be used as phosphorescent plate A.

By drawing a light bulb design a (b) on the silk screen 18 and rotating the transfer roller 17 coated with the paste from above the silk screen 18, the paste passes through the light bulb design a portion of the silk screen 18. , The design a is transferred onto the tile 1.

In FIG. 4, the luminous plate A comprises 2 to 10 parts by weight of the luminous material and one glaze material such as frit.
The mixture is mixed with 0 parts by weight to form a paste, the paste is applied to the tile 1 as a base material using a brush, and the paste is baked at 750 ° C. By using the brush, the paste can be drawn on the surface of the tile 1 as a picture, design, or character.

[0012] Since the melting temperature of the paste is lower than the firing temperature of the tile 1 or the like as the base material, the tile 1 is not affected at all by the firing temperature when the paste is applied and then fired. The luminous material and the glaze can be baked in a state where there is no occurrence, and the luminous plate A with high durability can be formed.

The luminous plate A is composed of two luminous materials.
-10 parts by weight and 10 parts by weight of a glaze material such as a frit are mixed to form a paste, and the paste is applied to the tile 1 using silk screen printing or a brush.
Although it is formed by baking at ° C., it is also possible to adopt a configuration that does not form a paste as described below. That is, a glaze is applied to the surface of the tile, a phosphorescent material is applied thereon, and baked at 750 ° C. A phosphorescent member is applied to the surface of the tile, a glaze is applied thereon, and baked at 750 ° C. Further, 95 parts by weight of the crushed glass material and 5 parts by weight of the resin paste are mixed, the mixture is formed into a plate shape to form a base material, and a phosphorescent material is applied to the substrate.
Bake at 0 ° C.
