<P>PROBLEM TO BE SOLVED: To provide a curable surface coating composition capable of more simply obtaining laminated polyester resin film which has further excellent weatherability, as compared with conventional compositions. <P>SOLUTION: This curable surface coating composition comprising a polyester resin, an organic polyisocyanate compound, an antioxidant and/or a photo stabilizer is characterized by using a polyester resin having 30 to 90°C glass transition temperature measured by using a Differential Scanning Calorimetry (DSC) method, as the polyester resin. The laminated polyester resin film obtained by laminating the cured film of the curable surface coating composition on the polyester resin film and a solar cell back sheet having a multilayered structure are also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
