| titleOfInvention | Polarizing film, polarizing plate, and manufacturing method of polarizing film |
| abstract | A polarizing film having excellent optical properties is provided. The polarizing film of the present invention is composed of a polyvinyl alcohol-based resin film containing iodine, has a single transmittance of 43.0% or more, and an orthogonal absorbance of 0.85 or more per 1 µm in thickness at a wavelength of 550 nm. Such a polarizing film includes, for example, forming a polyvinyl alcohol-based resin layer comprising iodide or sodium chloride and a polyvinyl alcohol-based resin on one side of a long thermoplastic resin substrate to form a laminate; And subjecting the laminate to an air-assisted stretching treatment, a dyeing treatment, an underwater stretching treatment, and a dry shrinkage treatment that shrinks by 2% or more in the width direction by heating while conveying in the longitudinal direction, in this order. Can be obtained by |
