Abstract

　下記式（Ａ－１）～（Ａ－３）を満たすセルロースエステルフィルムであって、少なくとも延伸方向に対して負の複屈折を示すアクリルポリマーおよび数平均分子量が３００以上２０００未満である芳香族末端ポリエステルを含有することを特徴とするセルロースエステルフィルム。（Ａ－１）　２０≦Ｒｏ≦１００、（Ａ－２）　７０≦Ｒｔ≦２００、（Ａ－３）　０．８２≦Ｒｏ（４８０）／Ｒｏ（６３０）≦０．９５、なお、Ｒｏ＝（ｎｘ－ｎｙ）×ｄ、Ｒｔ＝（（ｎｘ＋ｎｙ）／２－ｎｚ）×ｄ（式中、ｎｘはセルロースエステルフィルムの面内の遅相軸方向の屈折率を、ｎｙは面内で遅相軸に直交する方向の屈折率を、ｎｚは厚み方向の屈折率を、ｄはセルロースエステルフィルムの厚み（ｎｍ）をそれぞれ表す。波長は５９０ｎｍである。Ｒｏ（４８０）、Ｒｏ（６３０）はそれぞれ波長４８０ｎｍ、６３０ｎｍでのＲｏを表す。）
