METHOD FOR MANUFACTURING LAMINATED POLARIZING PLATE AND METHOD FOR MANUFACTURING POLARIZING PLATE

摘要

Provided is a method for manufacturing a laminated polarizing plate which can suppress the curl of a polarizing plate obtained by exfoliating and removing a substrate film from the laminated polarizing plate. The method for manufacturing a laminated polarizing plate comprises the following processes: forming an adhesive layer by coating a water-based adhesive including less than 7 wt% of polyvinyl alcohol resin on one or both surfaces of one surface of a protection film and a surface on a polarizer layer side of the polarizing laminated film including the polarizer layer on at least one surface of the substrate film; and bonding the polarizing laminated film and the protection film through the adhesive layer after adjusting the concentration of the polyvinyl alcohol resin among the adhesive layer to be equal to or higher than 7 wt%.
