Description of the Related Art Conventionally, a phosphorescent substance such as a ZnS: Cu-containing powder which is excited by natural visible light in the daytime and continuously emits light at night has been known. This phosphorescent substance is available in the form of ore powder. In general, it is excited by natural visible light or ultraviolet light by daylight and continues to emit light at night. Various materials using this phosphorescent substance have been developed. For example, luminous paints that use this luminous substance as pigments include door knobs for homes, the edges and handrails of emergency stairs, switches for indoor fluorescent lights, railroad crossings and station passages, clocks and dials for equipment, and parts for machinery and equipment. By applying the coating on the surface such as at night, the afterglow is emitted even at night or in a dark place, and the coating object can be improved so that it can be easily recognized by human eyes. The fluorescent plastic obtained by kneading a phosphorescent material such as ZnS: Cu into a resin can be formed into a desired shape. Therefore, the fluorescent plastic emits afterglow even at night or in a dark place and has a desired shape. A phosphor having a shape was obtained.

S: In a method of applying a luminous substance to an object to be coated with a luminous substance such as a Cu-containing powder or the like using a luminous substance as a pigment, the luminous paint is applied to the surface of the object having a predetermined shape. This required a new process. Also, it was not easy to apply a luminous paint to an already molded article.
Further, in this method, since the thickness of the coating film of the luminous paint is limited due to various conditions, the amount of the luminous substance to be applied is limited, and a desired luminescence may not be obtained in some cases. Also, in the method of molding and processing the fluorescent plastic,
Since the kind of plastic constituting the fluorescent plastic is limited to a certain kind of plastic from the viewpoint of affinity with the luminous substance and the like, it was not possible to select a material (plastic) according to the use of the molded article.

れる。The light-transmitting structure used in the present invention is a structure located outside the light storage material and having light-transmitting properties. Therefore, any structure that is located outside the phosphorescent material and has light transmittance is sufficient. The light-transmitting structure usually has a function of protecting and holding the phosphorescent material and forms the desired outer diameter of the molded product. The light transmittance of the light-transmitting structure used in the present invention is such that sunlight or light of an electric light is transmitted through the light-transmitting structure and absorbed by the light-storing material, and can emit afterglow from the light-storing material, and It is required at least that the afterglow be transmitted through the light transmitting structure and reach the outside. Therefore, the light-transmitting structure is preferably colorless and transparent, but may be colored as long as it has the light-transmitting property, and may not have sufficiently excellent transparency. You may. Also, in some cases, the color density of the afterglow emitted by the phosphorescent material is limited, so by coloring the light transmitting structure to have a predetermined color, a color that cannot be achieved by the phosphorescent material alone is obtained. , The light storage structure of the present invention including the light storage material and the light transmissive structure. As a material of such a light-transmitting structure, plastic is generally used, but an inorganic substance such as silicate glass such as silicate glass or soda-lime glass may be used. Plastics are preferred from the viewpoint of moldability, economy, and the like. Plastics used as the light-transmitting structure include polyethylene, polyvinylidene chloride, general-purpose resins such as polystyrene, ethylene-vinyl acetate copolymer, cellulose-based plastics, acrylic resins, polycarbonate resins,
Resins such as hard vinyl chloride and unsaturated polyester can be used, but acrylic resins are usually preferred from the viewpoint of gloss, transparency, weather resistance, economy, moldability, and the like. However, the required properties vary depending on the type of molded product such as a door knob of a house, an edge / rail of an emergency staircase, a switch of a fluorescent lamp in a room, etc., to be molded using the luminous structure of the present invention. Plastic depending on the application is used.
