PROBLEM TO BE SOLVED: To provide a production method of a laminated polarizing plate by laminating a protective film on a polarizer layer of a polarizing laminated film, characterized in that when a polarizing plate is obtained by peeling and removing a base film from the laminated polarizing plate, curling of the obtained polarizing plate can be suppressed.SOLUTION: The production method of a laminated polarizing plate includes: a step of applying an aqueous adhesive containing a polyvinyl alcohol resin by less than 7 wt.% on either a surface of a polarizing laminated film having a polarizer layer on at least one surface of a base film, the target surface being on the polarizer layer side, or one surface of a protective film, or on both of the surfaces to form an adhesive layer; and a step of controlling the concentration of the polyvinyl alcohol resin in the adhesive layer to 7 wt.% or more, and then bonding the polarizing laminate film and the protective film via the adhesive layer.SELECTED DRAWING: Figure 1 |
