Production method of polyvinyl alcohol film and polarizing film |
| abstract |
The present invention is a polyvinyl alcohol film comprising a vinyl alcohol polymer, and using a polyvinyl alcohol film immersed in water at 60 ° C. for 2 hours as a measurement sample, and using pulsed NMR to make a solid echo (Solid Echo) The NMR signal intensity at the 0.10 millisecond time point measured at 60 ° C is less than 78% of the initial intensity. According to the polyvinyl alcohol-based film of the present invention, it is possible to manufacture a polarizing film that improves the polarization performance and does not easily decrease the polarization performance under high humidity. |
