Composition, Optical Film, Method of Producing Optical Film, Polarizing Plate and Liquid Crystal Display Apparatus |
摘要 |
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.
