Manufacturing method and manufacturing apparatus of polarizing film |
| abstract |
The objective of this invention is to provide the manufacturing method and manufacturing apparatus of a polarizing film which do not easily generate shrinkage due to temperature change although the degree of crosslinking is increased. The method for producing a polarizing film of the present invention produces a polarizing film from a polyvinyl alcohol-based resin film, including an ultrasonic treatment step of immersing the polyvinyl alcohol-based resin film in an ultrasonic treatment bath in which ultrasonic waves are propagated, the ultrasonic treatment bath Contains potassium iodide and boron compounds. |
