Polyvinyl alcohol-type polymer film and polarizing film |
| abstract |
[PROBLEMS] To provide a PVA film having few defects and having good transparency, and a high-quality polarizing film produced therefrom with improved light transmittance. A PVA film comprising a PVA composition containing a PVA (A) and a nonionic surfactant (B), wherein the content of the nonionic surfactant (B) in the PVA composition is PVA (A) 100 And the content of at least one metal (C) selected from the group consisting of an alkali metal and an alkaline earth metal is 100 ppm or less based on the PVA (A); And a polarizing film produced from the PVA film. |
