| titleOfInvention | Production method of polyvinyl alcohol film and polarizing film |
| abstract | The present invention relates to a polyvinyl alcohol film comprising a vinyl alcohol-based polymer, the polyvinyl alcohol film immersed in water at 60°C for 2 hours is used as a measurement sample, and the solid echo method is performed at 60°C using pulsed NMR. The measured NMR signal intensity at 0.10 milliseconds 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 in which the polarization performance is improved and the polarization performance is not easily lowered even under high humidity. |
