PRODUCTION OF LIGHT-STORING RESIN MATERIAL AND LIGHT-STORING RESIN MATERIAL OBTAINED BY PRODUCTION THEREOF

摘要

PURPOSE: To obtain a light-storing resin material having a high luminous efficiency and capable of improving luminous persistency. CONSTITUTION: This method for producing a light-storing resin material comprises mixing a powder light-storing resin material 2 into a thermoplsastic resin material 1 having a high ultraviolet transmittance such as acrylic resin so as to intersperse particles 2a thereof among the material 1. The light-storing resin material is capable of bringing about efficient light storage and internal emission by ultraviolet transmitting action on deep parts of the thermoplastic resin material. This light-storing resin material is obtained by the above method.
