| titleOfInvention | Optical film, method for producing the same, and polarizing plate using the same |
| abstract | PROBLEM TO BE SOLVED: To provide an optical film used in various display devices such as a liquid crystal display device (LCD), in particular, a protective film for polarizing plate used in these display devices, and a method for producing an optical film useful for a retardation film. Optics that can prevent the formation of a film that adheres to the inner wall of the dissolution vessel in the dissolution process of the cellulose ester that is the raw material, prevent clogging of the filtration filter, and provide a high-quality optical film with high surface smoothness that is free of foreign matter A method for producing a film, an optical film produced by the method, and a polarizing plate using the optical film are provided. In a polymer dissolution step of an optical film manufacturing method by a solution casting film forming method, a solvent is dropped into a dissolution vessel 1 so as to form a cylindrical solvent flow, and an inner side of the cylindrical solvent flow is solved. The polymer powder is introduced into the container 1 so that the polymer powder is not brought into contact with the inner wall surface of the container above the upper surface of the polymer solution contained in the container 1.
