BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding composition using a thermoplastic polyurethane. Specifically, a soft, low shrinkage thermoplastic polyurethane resin is synthesized and cured, and then pulverized and dried using a grinder and activated alkali with rare earth metal ions. It is a molding composition blended with an inorganic photoluminescent pigment, which is a complex of earth metal aluminate, and injected into an injection molding machine. It is a photoluminescent molding composition that has a low shrinkage rate and can be processed with thermoplastic. It can be used.
