PROBLEM TO BE SOLVED: To obtain a coating material made of a thermoplastic resin, which controls a temperature rise by solar radiation in the inside of a material, controls a temperature drop by radiation cooling in the inside and has excellent transparency. SOLUTION: The coating material made of a thermoplastic resin comprises (A) a porphyrin derivative compound having an absorption band in a near infrared ray region at 760-2,000nm and (B) an inorganic compound having an absorption band in an infrared region at 5-25μm and 1.49-1.55 refractive index. A naphthalocyanine or a phthalocyanine compound is used as (A) the porphyrin derivative compound and a hydrotalcite compound, a lithium-aluminum double hydroxide salt compound, a lithium-aluminum-magnesium compound carbonate compound or a lithium-aluminum-magnesium compound silicate compound is suitably used as (B) the inorganic compound. A film, sheet, panel, filament, yarn, nonwoven fabric, woven fabric, hollow molding, etc., may be cited as the coating material. COPYRIGHT: (C)2006,JPO&NCIPI
