PROBLEM TO BE SOLVED: To provide a biaxially oriented polyester film that is excellent in adhesiveness to a hydrophilic functional coat layer, has good film appearance quality, and is excellent in film take-up performance.SOLUTION: The polyester film for glass lamination is a co-extruded laminated polyester composed of a polyester layer (B) substantially free from antimony element and a particle and a polyester layer (A) containing a particle having an average particle size (d) of 1.0-6.0 μm. The polyester layer (A) has a thickness (L) of 0.5d-1.5d and has a coating layer formed by coating the surface of the polyester layer (A) with an aqueous coating liquid which comprises: a water-soluble resin comprising an aromatic copolymerized polyester having a water-dispersible functional group and a vinyl alcohol unit as main components; and a polyglycerol polyglycidyl ether. |
