<P>PROBLEM TO BE SOLVED: To provide a cellulose ester film excellent in operativity, with wrinkles and peeling after adhesion restrained, while maintaining high anti-fogging characteristics. <P>SOLUTION: The anti-fogging cellulose ester film is produced by applying an alkali saponification process to at least one side of a cellulose ester film after formation thereof. It satisfies formula (1): 1.017≤S(t)/S(r)≤1.100, wherein S(t) is the dimensional change rate (%) in the film thickness direction when the relative humidity is changed from 20% at 23°C to 80% at 23°C, and S(r) is the dimensional change rate (%) in the film surface direction in changing the relative humidity 20% (23°C) to 80% (23°C). <P>COPYRIGHT: (C)2013,JPO&INPIT |
