| abstract |
A cellulose ester film characterized by containing a cellulose ester and at least one phosphonite compound. The cellulose ester film realizes reductions of environmental load, equipment load and production load attributed to solvent drying and recovery, and exhibits excellent optical properties, such as high transparency and less fluctuation of retardation in the direction of width. Further, the cellulose ester film ensures reduced staining and excels in processing stability. Moreover, there is provided a process for producing the cellulose ester film, and provided a polarizing plate in which the cellulose ester film is used as a protective film for polarizing plate, and provided a liquid crystal display unit making use of the polarizing plate. |
