<P>PROBLEM TO BE SOLVED: To manufacture a reflecting plate for collecting solar heat at high productivity, the reflecting plate having on the surface a coating film excellent in the durability of heat resistance, water resistance and the like, and excellent in tight adhesiveness, scratch resistance, impact resistance, weatherability and the like. <P>SOLUTION: A coating composition for coating the surface of a reflecting plate for collecting solar heat contains: a fluorine-containing copolymer (A) having a unit (α1) based on a fluoroolefin, and a unit (α2) having an ethylenically unsaturated group on the side chain; and a photoreaction initiator (B). A method for manufacturing a reflecting plate for collecting solar heat includes: coating the coating composition for coating the surface of the reflecting plate for collecting solar heat on the surface of a reflecting substrate to thereby form a coating layer; and thereafter carrying out light irradiation to cure the coating layer to thereby form the coating film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
