That is what is used for. However, in these cases, the preservability of the light energy is so low that it does not matter even if it is exposed to ultraviolet rays (it blocks the transmission of ultraviolet rays in painting), and the shape of the light-emitting body takes about 40 to 50 minutes in a dark room. Was so-called "surface emission" (surface emission).

無と言ってよい。Recently, a novel compound SrAl2O4 (a combination of strontium and alumina oxide) has been developed and attracted attention as a phosphorescent coating. "N night light"
It does not contain radioactive substances like self-luminous paint,
Even though it is a phosphorescent paint, it has the same luminous efficiency and luminous sustainability as a self-luminous paint, so it may be applied to various fields such as watches, signs, and daily necessities. However, this is because the light-accumulating property and the light-emitting property are pursued from the viewpoint of the component properties of the paint itself, and there is no necessity of bonding with the resin material. It can be said that there is no light-storing resin material intended for light storage and internal light emission by selecting a specific resin so far and correlating it with the ultraviolet transmittance.

It is intended to provide a method for obtaining a phosphorescent resin material having improved properties and a phosphorescent resin material obtained by the method.

In addition, the powdery phosphorescent material 2 is mixed in a state in which the particles 2a are scattered, and the ultraviolet-transmissive action to the deep part of the thermoplastic resin material 1 causes efficient phosphorescence and internal light emission of the phosphorescent resin material. It is a manufacturing method and is a phosphorescent resin material obtained by the manufacturing method. Of the above, acrylic resin is desirable as the thermoplastic resin material 1 having a high ultraviolet transmittance.

Since the light-storing resin material is mixed with the light-storing agent, the ultraviolet rays are efficiently permeated and absorbed up to the internal depth of the resin material 1 by applying ultraviolet rays as shown in FIG. Since the light is stored in 2, the so-called “internal light emission” can be performed, and the light emission time can be significantly extended (see the surface light emission phenomenon in FIG. 1).
