(57) [Summary] [Problem] It is difficult to generate precipitates or volatiles from a web during production, and has low retention and moisture permeability, very low elasticity even in a high-temperature and high-humidity environment, Provided is a high-quality polarizing plate that does not deteriorate a polarizer even in a state. SOLUTION: This is a cellulose ester film formed by a solution casting method using a dope containing a cellulose ester, an acrylic polymer and an organic solvent, wherein the acrylic polymer has a weight average molecular weight of 500. A cellulose ester film having a molecular weight of not less than 10,000. |
