| titleOfInvention | Polarizing film, polarizing plate, and manufacturing method of polarizing film |
| abstract | The subject of the present invention is to provide a polarizing film with excellent optical properties. The solution is: the polarizing film of the present invention is composed of iodine-containing polyvinyl alcohol resin film, the monomer transmittance is more than 43.0%, and the orthogonal absorbance per 1μm thickness at a wavelength of 550nm is more than 0.85. The polarizing film can be obtained, for example, by a manufacturing method comprising: forming a polyvinyl alcohol-based resin layer on one side of a long-shaped thermoplastic resin substrate to form a laminate, the polyvinyl alcohol-based resin layer Contains halide and polyvinyl alcohol-based resin; and, the layered body is sequentially subjected to aerial auxiliary stretching treatment, dyeing treatment, underwater stretching treatment, and drying shrinking treatment, and the drying shrinking treatment is to transport the layered body in the longitudinal direction And heat it to shrink by more than 2% in the width direction. |
