The present invention provides a laminated polyester film which is excellent in adhesion to a light diffusion layer or an anti-sticking layer, etc., when these layers are formed thereon. The laminated polyester film of the present invention comprises a polyester film and a coating layer formed on at least one surface of the polyester film, which coating layer is produced by applying a coating solution comprising an acrylic resin, an epoxy compound and an oxazoline compound thereonto. In the laminated polyester film of the present invention, a content of the acrylic resin in the coating layer is 20 to 90% by weight, a total content of the epoxy compound and the oxazoline compound in the coating layer is 10 to 80% by weight, and a weight ratio between the epoxy compound and the oxazoline compound (epoxy compound: oxazoline compound) is 1 to 10: 1 to 10.
本发明提供了一种层压聚酯薄膜,当在其上形成光扩散层或防粘层等时,这些层的附着力极佳。本发明的层压聚酯薄膜包括聚酯薄膜和在聚酯薄膜至少一个表面上形成的涂层,涂层是通过在其上涂抹由丙烯酸树脂、环氧化合物和噁唑啉化合物组成的涂层溶液而产生的。在本发明的层压聚酯薄膜中,涂层中丙烯酸树脂的含量为 20%至 90%(按重量计),涂层中环氧化合物和噁唑啉化合物的总含量为 10%至 80%(按重量计),环氧化合物和噁唑啉化合物(环氧化合物:噁唑啉化合物)的重量比为 1 比 10:1 比 10。
