(57) Abstract: [PROBLEMS] To provide a coating composition for forming a heat ray absorbing coat layer on a substrate, and a method capable of easily imparting the heat ray absorbing property thereto. A heat ray absorbing coating composition contains a film-forming resin component and an infrared absorbing agent, and the infrared absorbing agent is an infrared absorbing agent a (resin component 100 0.1 to 900 parts by mass of metal oxide semiconductor fine powder with respect to parts by mass), infrared absorber b (metal ion consisting of 0.01 to 20 parts by mass of divalent copper ion) and infrared absorber c. (At least 0.01 to 10 parts by mass of phthalocyanine compound). In the heat ray absorbing property imparting method, the coat layer containing the infrared absorbing agent is formed by applying the heat ray absorbing coating composition onto the surface of the substrate. As the substrate, a translucent material that constitutes an existing greenhouse facility can be used. |
