| description | PROBLEM TO BE SOLVED: To provide an easily adhesive white polyester film for solar cells, which is excellent in adhesion, durability, and long-term heat stability. SOLUTION: The easily adhesive white polyester film for solar cells has a coating layer which contains a urethane resin containing an aliphatic polycarbonate polyol as a constituent and a crosslinking agent as main components and in which in the infrared spectroscopy spectrum of the coating layer, the ratio (A1460/A1530) between the absorbance (A1460) in the vicinity of 1,460 cm-1deriving from an aliphatic polycarbonate component and the absorbance (A1530) in the vicinity of 1,530 cm-1deriving from a urethane component is 0.50-1.55 on a white polyester film which contains a polyester polymerized by using a polycondensation catalyst containing aluminum and/or its compound and a phosphorus compound having an aromatic group in a molecule as a main constituent, has a whiteness of at least 50, contains 3-50 mass% of fine particles of 0.1-3 μm in an average particle size, has a film acid value of 1-30 (eq/ton), and is 20-500 μm in thickness.
