Summary:To provide a laminate having a polyphenylene sulfide film on at least a single surface of a polyester film, achieving both of adhesiveness and breaking elongation of the laminate having the polyphenylene sulfide film on at least the single surface of the polyester film, and excellent in processability.SOLUTION: There is provided a laminate having a polyphenylene sulfide film on at least a single surface of a polyester film, and satisfying followings: (1) an endothermic peak temperature (Ta) is observed at less than 100°C when measured by DSC (differential scanning calorimetry); (2) peeling strength between films in a peeling test at 180° is 3.8 N/cm or more; (3) breaking elongation is 100% to 150%; and (4) a rubbing number required by detachment in rubbing resistance evaluation is 70 or more.SELECTED DRAWING: None 【課題】ポリエステルフィルムの少なくとも片面にポリフェニレンサルファイドフィルムを有する積層体の密着性と破断伸度を両立し、加工性に優れた、ポリエステルフィルムの少なくとも片面にポリフェニレンサルファイドフィルムを有する積層体を提供する。【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フェニレンサルファイドフィルムを有する積層体であって、以下を満たすことを特徴とする積層体。(1)DSC(示差走査熱量測定)で測定した際に、吸熱ピーク温度(Ta)が100℃未満に観測されること。(2)180°の剥離試験によるフィルム間の剥離強度が3.8N/cm以上であること。(3)破断伸度が100%以上150%以下であること。(4)耐もみ性評価にて剥離までに要するもみ回数が、70回以上であること。【選択図】なし
