  A composition for melt casting film formation that excels in not only uniformity of retardation being an optical characteristic, especially uniformity of retardation in the direction of film width, but also contrast; and relevant thereto, an optical film, process for producing the optical film, polarization plate and liquid crystal display apparatus. Accordingly, there is provided a composition for melt casting film formation containing a cellulose ester in an amount of 50 mass% or more, characterized in that the free acid content of the composition is 50 ppm or less.

  一种熔融铸造成膜用组合物，它不仅在作为光学特性的延迟均匀性（尤其是在薄膜宽度方向上的延迟均匀性）方面表现出色，而且在对比度方面也表现出色；以及与此相关的光学薄膜、光学薄膜生产工艺、偏振片和液晶显示装置。因此，本发明提供了一种用于熔融铸造成膜的组合物，该组合物中纤维素酯的含量为 50 质量％或更多，其特征在于该组合物中的游离酸含量为 50 ppm 或更少。

  A cellulose ester film that excels in uniformity of retardation as an optical property, especially uniformity of retardation in the direction of film width, and further contrast; a process for producing such a cellulose ester film; and making use of the film, an optical film, polarizing plate and liquid crystal display unit. There is provided a process characterized by subjecting, to melting film formation, a solid cellulose ester having been suspension washed with a poor organic solvent to cellulose ester in the presence of an antioxidant so that the content of free acids in the cellulose ester is 50 ppm or less.
