Zusammenfassung:To provide a resin composition capable of forming a film having high durability against bending and to provide a film comprising the resin composition.SOLUTION: There is provided a resin composition comprising: (A) a cyclic olefin copolymer A which is a copolymer of a cyclic olefin monomer and an α-olefin having 3 or more and 20 or less carbon atoms and comprises a resin having two or more glass transition temperatures in the range of 0°C to 300°C as determined by viscoelasticity measurement in which the amount of the structural unit derived from the α-olefin is 10 mol% or more and 50 mol% or less based on the total structural units; and (B) a cyclic olefin copolymer B which is a copolymer of a cyclic olefin monomer and an α-olefin having 2 or more and 20 or less carbon atoms and comprises a resin having one glass transition temperature in the range of 0°C to 300°C as determined by viscoelasticity measurement in which the amount of the structural unit derived from the α-olefin is 10 mol% or more and 50 mol% or less based on the total structural units.SELECTED DRAWING: None 【課題】折り曲げに対する耐久性が高いフィルムを形成可能な樹脂組成物と、当該樹脂組成物からなるフィルムとを提供すること。【解決手段】環状オレフィンモノマーと、炭素原子数3以上20以下のα-オレフィンとの共重合体であって、α-オレフィンに由来する構造単位の量が、全構造単位に対して10モル%以上50モル%以下であり、0℃~300℃の範囲内に粘弾性測定により求められるガラス転移温度を2つ以上有する樹脂からなる(A)環状オレフィン共重合体A、及び環状オレフィンモノマーと、炭素原子数2以上20以下のα-オレフィンとの共重合であって、α-オレフィンに由来する構造単位の量が、全構造単位に対して10モル%以上50モル%以下であり、0℃~300℃の範囲内に粘弾性測定により求められるガラス転移温度を1つ有する樹脂からなる(B)環状オレフィン共重合体Bを含む樹脂組成物を用いる。【選択図】なし
