Abstract

(57) [Abstract] [PROBLEMS] To provide a gemstone that does not adversely affect the stone in a simple process and that brings about a beautiful color change by the gemstone alone without sealing the phosphorescent paint. SOLUTION: A concave portion is provided in a part of a jewel, a mixture material containing a phosphorescent paint and a UV curable resin is applied thereto, and a high pressure mercury lamp is irradiated to cure the phosphorescent paint. When the cured phosphorescent paint is exposed to light, you can enjoy the phenomenon of light emission through a jewel.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a jewel coated with phosphorescent paint.

[0002]

[Prior art]

 Conventionally, gems coated with this type of phosphorescent paint are those in which a colored phosphorescent paint is applied to the surface of a decorative body (see Japanese Utility Model Publication No. 59-91125), or, as shown in FIG. It is known that phosphorescent paint 23 is applied to the base, and this is engaged with a pedestal 25, and the concave portion 26 provided on the pedestal or the side surface of the jewel is fixed with an adhesive 24 such as epoxy (Actual No. 07-023416). See the bulletin).

[0003]

[Problems to be solved by the device]

 In the gemstone having the above structure, heat must be applied when the gemstone is bonded to the pedestal, which adversely affects the stone. Further, the phosphorescent paint has a property of being soluble in water, and in order to prevent this, it is necessary to combine the jewelry with the pedestal to seal the phosphorescent paint, which requires a long processing time.

The present invention has been made in order to solve such a problem, and its purpose is to not adversely affect stones in a simple process and to prevent the phosphorescent paint from being sealed. It aims to provide gemstones that bring about beautiful color changes by themselves.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the gemstone of the present invention is provided with a concave portion in a part of the gemstone, and has a mixture containing a phosphorescent paint and a UV curable resin therein. Further, it is preferable that the above-mentioned phosphorescent paint comprises an alumina-based metal oxide and a rare earth element.

[0006]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. 1A and 1B are a front view and a sectional view of a jewel of the present invention. The jewel 1 is made of, for example, a transparent material such as blue topaz or amethyst, and a shallow recess 2 having an arbitrary shape is provided on the back surface thereof. A mixture material 3 composed of a phosphorescent paint and a UV curable resin is applied to the concave portion 2. As the phosphorescent material, a material based on alumina-based metal oxide, to which a rare earth element was added as a light emitting source, and sintered in an atmosphere was used. This was made into a powder having a particle size of 20 to 30 μm, and a UV curable resin was mixed with this and applied to the recess 2 as a mixed material 3. As the UV curable resin, "Celcor UV PAL screen ink (ultraviolet curable)" manufactured by Teikoku Ink Mfg. Co., Ltd. was used, and the mixed material 3 applied to the recess 2 was irradiated with a high pressure mercury lamp for about 10 seconds.

The mixture material 3 that has been irradiated and cured in this way remains in the recesses 2 as a phosphorescent paint. Therefore, when light hits a jewel, the phosphorescent paint stores energy for light emission, and depending on the stored energy. The luminescence phenomenon continues. This allows the phosphorescent paint drawn in any shape to shine through transparent jewels, and you can enjoy various color changes depending on the combination of stone color and paint. Luminance of the light emission gradually decreases as the stored energy decreases, but by placing the jewelry in a bright place, the light can be stored again inside the phosphorescent paint, which causes repeated color changes. You can enjoy it.

In FIG. 1, this jewel is provided with a mounting hole 4 for attaching a chain and is used for a pendant or a necklace. However, since it does not require a structure for sealing the phosphorescent paint, other decorations such as rings and earrings are not required. It goes without saying that more flexible designs can be applied to products.

[0009]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects. Since this device does not use an adhesive, it does not add heat during the process and does not adversely affect the stone. Furthermore, since the UV-curable resin hardens the phosphorescent paint, it is possible to apply the phosphorescent coating directly to the jewel, and it is not necessary to attach a pedestal or the like, and the beauty of the jewel alone can be further utilized. Further, since the light-emitting material is hardened by the UV curable resin, it is also excellent in water resistance and the phosphorescent paint does not dissolve in water.
