| description | PROBLEM TO BE SOLVED: To provide a polyimide film having high peelability from base material and capable of preventing the occurrence of a poor appearance, and a method of producing the same.SOLUTION: The polyimide film comprises polyimide and at least one selected from the group consisting of γ butyrolactone and N, N-dimethyl acetamide, and has a yellowness of 10 or less. When a mass ratio of the γ butyrolactone is G(ppm) and a mass ratio of the N, N-dimethyl acetamide is D(ppm), the polyimide film satisfies 30≤G+D≤10000.SELECTED DRAWING: None
【課題】基材からの剥離性が高く、良好な外観不良を実現可能なポリイミド系フィルム、及び、その製造方法を提供する。【解決手段】このポリイミド系フィルムは、ポリイミドと、γブチロラクトン及びＮ，Ｎ−ジメチルアセトアミドからなる群から選ばれる少なくとも一つと、を含有し、黄色度が１０以下である。また、γブチロラクトンの質量割合をＧ（ｐｐｍ）、Ｎ，Ｎ−ジメチルアセトアミドの質量割合をＤ（ｐｐｍ）としたときに、３０≦Ｇ＋Ｄ≦１００００を満たす。【選択図】なし |
