Antifogging film

Abstract

An antifogging film includes a film base and a saponified layer. The film base is formed of cellulose triacetate as cellulose acylate. The saponified layer is provided on a first base surface of the film base and serves as a first film surface of the antifogging film. The saponified layer contains saponified cellulose triacetate. The antifogging film is configured such that the first film surface has a contact angle of 20° or less 15 seconds after dropping of pure water thereto. In a case where the amount of acyl groups of the first film surface is X and the amount of acyl groups of a second base surface is Y, an acyl group ratio obtained by X/Y is 0.7 or less.
