| titleOfInvention | Polarizing film, method for producing the polarizing film, polarizer, and optical laminate |
| abstract | An object of the present invention is to provide a polarizing film free of color unevenness.n n n The polyvinyl alcohol-based film is treated in the order of swelling, dyeing, boric acid treatment and water washing treatment, uniaxial stretching is carried out in the boric acid treatment step and / or the previous step, and further stretching treatment is performed on the film. A polarizing film obtained by maintaining a substantially constant tension applied thereto, wherein a polyvinyl alcohol-based film is continuously treated in the order of swelling treatment, dyeing treatment, boric acid treatment, and water washing treatment, and a boric acid treatment step and / or a step before it. It carries out uniaxial stretching at, and manufactures by tension control of the said film in each process after an extending | stretching process. As a result, traveling of a film can be stabilized and color unevenness can be reduced. |
