Polyvinyl alcohol film |
| abstract |
A wide polyvinyl alcohol film which is effective in producing a high-performance polarizing film reduced in optical unevenness caused by dyeing unevenness or stretching unevenness. The polyvinyl alcohol film is one formed from a film-forming raw liquid containing a polyvinyl alcohol polymer and a plasticizer. In a TD area in the film, the maximum difference (Ry) between the plasticizer contents in the film and the average content is 2% or smaller. The film has a plasticizer-content trough/crest curve regarding TD content fluctuations which has an average distance (Sm) of 5 cm or longer. |
