Production method of polyvinyl alcohol film, polyvinyl alcohol film, and polarizing film |
abstract |
PROBLEM TO BE SOLVED: To provide a method for producing a polyvinyl alcohol film capable of obtaining a polyvinyl alcohol film having a low haze and few defects without performing a special cast type cleaning or repair. An aqueous solution of a polyvinyl alcohol resin is continuously cast into a cast mold to form a film, and the resulting film is peeled off from the cast mold and then dried. A method for producing a polyvinyl alcohol-based film, wherein the cast-type surface before rolling is continuously hydrophilized with a surfactant and has a contact angle with water of 5 to 50 °. [Selection figure] None |
