Title:
OPTICAL LAMINATE ROLL AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2018013690
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an optical laminate roll that allows a master roll of a polarizing plate in which a polarization film and a reflective polarizer are laminated, to be produced efficiently by the roll-to-roll system, and a method of producing the same.SOLUTION: In an optical laminate roll, an optical film that has a long belt-like polarization film 2 having a transmission axis in width direction W1, and an optical reflective polarizer 3 having a transmission axis in width direction W2, are laminated through a cured product of an energy ray-curable adhesive, the reflective polarizer 3 having an average transmittance of 4% or more in a wavelength region of 280-320 nm.SELECTED DRAWING: Figure 2
