| titleOfInvention | Method for producing polarizing film |
| abstract | The invention provides a method for manufacturing a polarizing film, which properly inhibits the breakage of a polarizing plate during the manufacturing process and easily realizes the stretching with high magnification. The method for producing a polarizing film of the present invention comprises: a stretching step of stretching a strip-shaped resin film made of a polyvinyl alcohol resin as a material to obtain a stretched film; a bonding step of bonding a tape-shaped base film to at least one surface of the stretched film to obtain a laminated film in which the stretched film and the base film are laminated; and a polarizing plate forming step of dyeing the stretched film with a dichroic dye and stretching the entire laminated film in the longitudinal direction to form a polarizing plate from the stretched film, wherein the stretch ratio in the longitudinal direction of the base film in the laminating step is smaller than the stretch ratio in the longitudinal direction of the stretched film in the stretching step. |
