LAMINATED FILM, PROCESS FOR PRODUCING LAMINATED FILM, PROCESS FOR PRODUCING POLARIZABLE LAMINATED FILM

摘要

Provided are a laminated film, a manufacturing method of the laminated film, a method for manufacturing a polarizing laminated film from the laminated film, and a method for manufacturing a polarizing plate from the laminated film. The laminated film is formed with a resin layer formed of a polyvinyl alcohol-based resin on a substrate film, and does not generate the unevenness of optical stripes when being introduced in the polarizing plate. The laminated film is formed with a resin layer formed of a polyvinyl alcohol-based resin on a gauge rod-type substrate film. The maximum amplitude of the thickness in the width direction of the resin layer is less than or equal to 2.0 m.
