Optical polyester film

The present disclosure relates to an optical polyester film having very good optical and physical properties, which exhibits good coating properties, and achieves a uniform adhesive force and a uniform light-resistant adhesive force between the primer layer of the optical polyester film and a UV-curable resin coating layer such as an AG coating or a hard coating layer to reduce defective products, prolong its service life and achieve high quality. 本公开涉及具有非常好的光学特性和物理特性的光学聚酯膜，其显示出良好的涂覆特性，并且实现了光学聚酯膜的底漆层与可UV固化树脂涂层例如AG涂层或硬涂层之间均匀的粘合力和均匀的耐光粘合力以减少缺陷产品、延长其使用寿命并实现高品质。
