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.

Abstract: A bar coater includes: a bar for applying a coating liquid to a web; a support member which is arranged on a lower side of the bar so as to rotatably support the bar; a weir arranged at an upstream side of the bar, the weir having a leading end surface at its distal end portion to form a bead of the coating liquid in a space between the leading end surface and the web; a reservoir including the bar, the support member and the weir, the reservoir for accumulating the coating liquid; a pump for supplying the coating liquid to the reservoir; a liquid discharge passage through which the coating liquid excessively supplied to the reservoir is discharged; and a controlling device for controlling the pump so as not to cause distortion of a dynamic contact line which is formed at interface between the coating liquid and the atmosphere.
