NEAR-INFRARED ABSORPTIVE POLYESTER RESIN COMPOSITION AND PRODUCTION METHOD OF THE SAME, AND NEAR-INFRARED ABSORPTIVE POLYESTER RESIN MOLDED BODY

摘要

To provide a near-infrared absorptive polyester resin composition molded body having near-infrared absorptive fine particles uniformly dispersed in a polyester resin without aggregation, and a near-infrared absorptive polyester resin composition and the like to be used for manufacturing the above molded body.SOLUTION: The near-infrared absorptive polyester resin composition is to be used for manufacturing a near-infrared absorptive polyester resin molded body and comprises a polyester resin, near-infrared absorptive fine particles and a high boiling point solvent. The near-infrared absorptive fine particles are constituted by composite tungsten oxide fine particles represented by a general formula of MyWOz and having a hexagonal crystalline structure. The high boiling point solvent is constituted by a diol compound (a compound selected from polyester polyol, aliphatic diol, alicyclic diol and aromatic diol) that has a boiling point of 195°C or higher and a hydroxyl group at both molecular ends and that is liquid at room temperature.SELECTED DRAWING: None
