titleOfInvention | Production method of polyvinyl alcohol film and polarizing film |
abstract | The present invention is a polyvinyl alcohol film, which is a polyvinyl alcohol film containing a vinyl alcohol-based polymer in which spin-spin relaxation of 1H measured by a solid echo method at a temperature of 60°C using pulsed NMR is obtained. The free induction decay curve of the free induction decay curve is separated into three curves derived from the three components of A component, B component, and C component according to the order of relaxation time from short to long. The measured relaxation time of B component is 0.03 milliseconds to 0.05 milliseconds, and the component ratio is 30% to 50% inclusive. According to the polyvinyl alcohol film of the present invention, it is possible to manufacture a polarizing film without causing uneven dyeing while making the polarizing performance favorable. |
