METHOD FOR MANUFACTURING POLARIZER

摘要

A method for manufacturing a polarizer, including: a step in which a polarizing film is fabricated by subjecting a polyvinyl-alcohol resin film to a dyeing process, a boric-acid process, and a uniaxial stretching process; a step in which an active-energy-ray-curable adhesive is applied to one surface of a transparent film or transparent films; a step in which a laminate is fabricated by bonding the surface(s) of the transparent film(s) to which the adhesive was applied to one or both surfaces of the polarizing film, and sandwiching with bonding rolls; and a step in which a polarizer is fabricated by exposing the laminate to active-energy rays. This method for manufacturing a polarizer is characterized in that the diameters of the bonding rolls used in the laminate-fabrication step are in the 30-270 mm range.
