POLARIZING LAMINATE FILM, METHOD FOR MANUFACTURING POLARIZING PLATE OR POLARIZING PLATE WITH BASE FILM, DOUBLE-SIDED LAMINATE FILM, DOUBLE-SIDED POLARIZING LAMINATE FILM, DOUBLE-SIDED BONDING FILM, AND SINGLE-SIDED BONDING FILM

摘要

PROBLEM TO BE SOLVED: To suppress curl of a film generated in a stretching process, a drying process after dyeing, when storing a stretched film or the like, in a manufacturing process of a polarizing plate which is thin and has high polarization performance.SOLUTION: A method for manufacturing a double-sided polarizing laminate film having a base film and polarizer layers formed on both surfaces of the base film includes: a resin layer forming process for forming polyvinyl alcohol resin layers on both surfaces of the base film to obtain a double-sided laminate film; a stretching process for stretching the double-sided laminate film; and a dyeing process for dyeing the polyvinyl alcohol resin layers on both surfaces of the double-sided laminate film after the stretching with a dichroism pigment and performing crosslinking treatment to form the polarizer layers, in this order.
