Description

すなわち、本発明の要旨は、下記構造式１および２で示される構成要素を繰返し単位として有する帯電防止性高分子化合物と、熱硬化性樹脂とを含有する塗布層をポリエステルフィルムの一方の面に有することを特徴とする表面保護フィルム用ポリエステルフィルム、および当該フィルムの塗布層の反対側の面に微粘着層を有することを特徴とする光学部材表面保護用ポリエステルフィルムに存する。 That is, the gist of the present invention is that a coating layer containing an antistatic polymer compound having a constituent represented by the following structural formulas 1 and 2 as a repeating unit and a thermosetting resin is provided on one surface of a polyester film. It has the polyester film for surface protective films characterized by having, and the polyester film for surface protection of an optical member characterized by having a slight adhesion layer in the surface on the opposite side of the coating layer of the said film.
