<P>PROBLEM TO BE SOLVED: To provide a production method of a polarizing laminate film, in which tearing in an orientation direction in a dyeing process can be well suppressed. <P>SOLUTION: The production method of a polarizing laminate film includes steps of: obtaining a laminate film by forming a polyvinyl alcohol resin layer on one surface of a substrate film comprising a thermoplastic resin and a rubber component dispersed in the resin; obtaining an oriented film by uniaxially orienting the laminate film; obtaining a dyed film by dyeing the polyvinyl alcohol resin layer of the oriented film with a dichroic dye; obtaining a crosslinked film by immersing the polyvinyl alcohol resin layer of the dyed film in a solution containing a crosslinking agent to form a polarizer layer; and drying the crosslinked film. <P>COPYRIGHT: (C)2013,JPO&INPIT |
