| titleOfInvention | Polyvinyl alcohol-based film, polarizing film, polarizing plate, and method for producing polyvinyl alcohol-based film |
| abstract | The present invention provides a polyvinyl alcohol-based film, which is excellent in the balance of swelling property and stretchability during the production of polarizing films, does not break during the production of thin polarizing films, and can exhibit high polarizing performance without color. A polarizing film with little uniformity, and a polarizing film and a polarizing plate using the polyvinyl alcohol-based film, and the above-described polyvinyl alcohol-based film are provided. The polyvinyl alcohol-based film of the present invention is a long polyvinyl alcohol-based film having a thickness of 40 μm or less, and is characterized by the swelling degree (S A ) and the swelling degree in the width direction when immersed in water at 30° C. for 5 minutes (S X ), the degree of swelling in the longitudinal direction (S Y ), and the degree of swelling (S B ) when uniaxially stretched in water at 30° C. at a stretching speed of 0.12 m/min so that the stretching ratio is 3 times The following formulae (1) to (3). 190% ≤SA≤230 %...(1) 220% ≤SB≤310 %...(2) 1.01≤S Y /S X≤1.20 ...(3). |
