Title:
A manufacturing method of a polymer film
Document Type and Number:
Japanese Patent JP6277164
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a polymer film, in which the hardness of the polymer film can be made higher and the generation of interference unevenness can be suppressed.SOLUTION: The method for producing the polymer film comprises the steps of: flow-casting a dope containing an organic solvent-soluble resin and a polymerizable compound to obtain a web; irradiating the web with ultraviolet light so that a reaction ratio of the polymerizable compound becomes 3-30%; and heating the web, which is irradiated with the ultraviolet light, at the temperature equal to or higher than 140°C to obtain the polymer film.SELECTED DRAWING: None
