<p>The present invention relates to a method for producing a polarizing laminate film that includes a base film, a primer layer, and a polarizer layer in this order, wherein a primer solution employed to improve the adhesion between the base film and a polyvinyl-alcohol-based resin layer contains at least one type of cross-linking agent selected from a group consisting of dialdehyde-based cross-linking agents, isocyanate-based cross-linking agents, and metal-based cross-linking agents. With the present invention, it is possible to provide, during the method for producing the polarizing laminate film, the primer layer with water resistance that will prevent the polyvinyl-alcohol-based resin layer from peeling from the base material even at the time of immersion into a dyeing solution or a cross-linking solution.</p> |
