METHOD FOR PRODUCING ACRYLIC RESIN-CONTAINING FILM, ACRYLIC RESIN-CONTAINING FILM, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a method for producing an acrylic resin-containing film by solution casting whereby a dope composition is cast onto a substrate, allowed to dry, and then peeled from the substrate. The method for producing an acrylic resin-containing film comprises a dope preparation step for preparing a dope composition by stirring and dissolving an acrylic resin, cellulose ester resin, and an additive in an organic solvent inside a dissolution cell to form a dope composition and adding water such that the water content is brought to 0.8 to 2.0 mass% in terms of the total amount of dope composition. The additive is a polymer compound having a hydrogen bond component, and is added in an amount between 1 to 10 mass% per total amount of organic solvent. By means of the method for producing an acrylic resin-containing film, and the like, there is good adhesion between the dry film and the polarizer, and productivity is high.
