Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a resin composition optimal for an optical film, which has excellent heat resistance, can form a film with excellent durability, and is used as a polarizer protective film with an extremely small phase difference in the thickness direction.SOLUTION: A resin composition contains a composition (X) comprising: a polycarbonate resin (A) that has a structural unit (a-1) derived from the dihydroxy compound represented by the general formula (1) in the figure and a structural unit (a-2) derived from a dihydroxy compound other than the dihydroxy compound represented by the general formula (1); and a resin (B) that has a structural unit (b-1) derived from maleic anhydride and a structural unit (b-2) derived from styrene.SELECTED DRAWING: None 【課題】耐熱性に優れ、フィルムとした際の耐久性に優れ、さらに厚み方向の位相差が極めて小さい偏光子保護フィルムに用いられる光学フィルムに最適な樹脂組成物を提供することにある。【解決手段】下記一般式（１）で表されるジヒドロキシ化合物に由来する構造単位（ａ−１）および下記一般式（１）で表されるジヒドロキシ化合物以外のジヒドロキシ化合物に由来する構造単位（ａ−２）を有するポリカーボネート樹脂（Ａ）と、無水マレイン酸に由来する構造単位（ｂ−１）およびスチレンに由来する構造単位（ｂ−２）を有する樹脂（Ｂ）を含む組成物（Ｘ）を含有する樹脂組成物。【選択図】なし
