GRANULAR LUMINOUS MATERIAL COMPOSITION, MOLDING MATERIAL, MOLDED PRODUCT AND MASTER BATCH

摘要

PROBLEM TO BE SOLVED: To provide a freely colorable granular luminous material composition having hardly reduced properties such as impact resistance originally possessed by a resin, having brightness of afterglow kept by reducing the decrease thereof caused by abrasion with a cylinder and a screw at molding, having excellent cost and providing a molded product with excellent appearance; and to provide a molding material, a molded product and a master batch. SOLUTION: The granular luminous material composition contains 5-60mass% luminous pigment dispersed in a resin not melted at a molding temperature of a thermoplastic resin to be molded. The dispersoid is pulverized so as to have 10-1,000μm grain size. The molding material, the molded product and the master batch are also provided. COPYRIGHT: (C)2004,JPO&NCIPI
