PROBLEM TO BE SOLVED: To provide a polyester film which has excellent antistatic properties and is excellent in durability of antistatic properties.SOLUTION: The laminated polyester film has, on at least one surface of a polyester film, a coating layer formed from a coating liquid containing a polystyrene sulfonic acid or its derivative and an acrylic resin or a polyvinyl alcohol resin. In a method for producing the laminated polyester film, a coating liquid containing a polystyrene sulfonic acid or its derivative and an acrylic resin or a polyvinyl alcohol resin is applied to at least one surface of a polyester film to form a coating layer.SELECTED DRAWING: None 【課題】 優れた帯電防止性を有し、かつ帯電防止性の耐久性に優れたポリエステルフィルムを提供する。【解決手段】 ポリエステルフィルムの少なくとも片面に、ポリスチレンスルホン酸またはその誘導体と、アクリル樹脂またはポリビニルアルコール樹脂とを含有する塗布液から形成された塗布層を有することを特徴とする積層ポリエステルフィルム、および、ポリエステルフィルムの少なくとも片面に、ポリスチレンスルホン酸またはその誘導体と、アクリル樹脂またはポリビニルアルコール樹脂とを含有する塗布液を塗布して塗布層を形成することを特徴とする積層ポリエステルフィルムの製造方法。【選択図】 なし
