Laminate, method for producing polyvinyl alcohol-based film for producing polarizing film, method for producing polarizing film, and method for storing or transporting polyvinyl alcohol-based film for producing polarizing film

摘要

PROBLEM TO BE SOLVED: To provide a laminate capable of preventing deterioration in a polyvinyl alcohol film such as scratches, contamination, deformation and changes in optical performance caused during storage, conveyance and transportation of the film, and to provide a polyvinyl alcohol film for manufacturing a polarizing film and a polarizing film having excellent in-plane uniformity obtained from the above laminate, and a method for storing or transporting a polyvinyl alcohol film for manufacturing a polarizing film using the above laminate.SOLUTION: The laminate comprises a polyvinyl alcohol film for manufacturing a polarizing film and a protective film stuck to at least one surface of the polyvinyl alcohol film, in which the polyvinyl alcohol film has a thickness of 60 μm or less, and the polyvinyl alcohol film and the protective film are stuck to each other with an adhesive force of 1 to 30 mN/20 mm.SELECTED DRAWING: None
