Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminous phosphor that can be used in various plastic products.

[0002]

2. Description of the Related Art Products made of plastic such as household products and stationery are usually formed transparent or semi-transparent by applying various colors, or formed by kneading a phosphorescent pigment into a resin. .

[0003]

However, a product obtained by kneading a conventional phosphorescent pigment in a resin emits light, so that the product can be immediately recognized even at night and can exert a design effect. However, unless the phosphorescent pigment is kneaded in a relatively large amount, it does not emit light effectively, so the amount of the phosphorescent pigment used is large and it is not economical.
In addition, the entire product emits a flicker, which lacks the impact of appealing to the viewer.

The present invention has been made in view of the above points, and at least the amount of the phosphorescent pigment used can effectively emit light, and the emitted light itself is clear. Intended to provide the body.

[0005]

The phosphorescent material according to the present invention is characterized by having a transparent or semitransparent base material and a large number of phosphorescent materials mixed in the base material.

In the phosphorescent material of the present invention, a large number of phosphorescent materials mixed in the base material emit light and can be clearly recognized even in the absence of illumination, and the entire phosphor does not emit light. Since only a large number of mixed phosphorescent materials emit light, the light emission can be clearly seen and the interior effect is enhanced.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the luminous phosphor of the present invention,
A large number of phosphorescent materials are mixed in the base material. This phosphorescent material has a part that emits light, which is composed of a phosphorescent pigment, and the form thereof can be flat or granular.
In the case of a flat plate, there are a flat plate formed of only the phosphorescent pigment, and a transparent or translucent film provided with a phosphorescent pigment layer on one side or both sides. The flat plate may have various shapes such as a quadrangle, a circle, and a hexagon. In the case of granular particles, there are those in which a phosphorescent pigment layer is provided on the surface of a granular material made of synthetic resin or the like, and resins in which a phosphorescent pigment is mixed are formed into granular particles. Various shapes such as a sphere and a polyhedron can be adopted as the shape of the granular material.

[0008] The amount of mixing a flat photoluminescent material to the substrate, the substrate 1 cm ³ per summed area preferably 0.05～5Cm ² of photoluminescent material, and more preferably 0.5～2Cm ² . When the mixed amount is less than 0.05 cm ² , the amount of emitted light is small and sufficient or the effect cannot be exhibited. Further, if the mixed amount exceeds 5 cm ² , the base material may become brittle and sufficient strength may not be obtained.

The flat phosphorescent material varies depending on the product to be used, but generally the size is 0.01 to 400 m.
m ² is preferable, and 0.25 to 30 mm ² is more preferable. Then, a predetermined number of sheets are mixed according to each area so as to match the above-mentioned mixed amount.

The color of the phosphorescent pigment is not particularly limited, and red, yellow, blue, green, soda color, milky white and the like can be used. Further, a fluorescent dye or the like may be used together with the phosphorescent pigment to form a light-emitting body by fluorescence storage.

The substrate is not particularly limited as long as it is transparent or semi-transparent and can transmit the light emitted from the luminous phosphor. For example, polyethylene resin, polypropylene resin,
Polyester resin, polyurethane resin or the like can be used.

The phosphorescent substance according to the present invention may form a product by itself (for example, a container is formed of the phosphorescent substance) or may be formed in a sheet shape to cover the surface of the product (eg, a product). , Stick a sheet of phosphorescent material on the surface of the container).

Products in which the phosphorescent material of the present invention can be used include household products, stationery, jewelry, ornaments,
The present invention is not particularly limited to toys, and can be used for all products that can utilize the accumulated light emission.
For example, lighting strings, doorknobs, door handles, switches, outlets, handrails, non-slip stairs, luminaire covers, luminaire covers, luminaire stand frames, key chains, cell phones, cell phone straps, software. Lures, lures, floats, dolls, character products, cups, washbasins, bath tubs, pens, strings / ropes, furniture / shelf, super bowls, nameplates, canes, tissue cases /
Covers, poles, tapes, stickers, lines, sheets, tiles, plastic boards, blinds, signs, signs, banners, flags, security equipment, clothes, wallpapers, curtains, films,
It can be used for posters, calendars, puzzles, cards, business cards, book covers, cardboards, cardboards, cosmetic containers, etc. Further, the product is not limited to the solid product as described above, and may be a liquid product, for example,
It can be used for adhesives, nail polish and paints. In this case, the substrate is in liquid form.
