THIN AND HIGH-FUNCTIONAL POLARIZING FILM, OPTICAL FILM LAMINATE INCLUDING THIN AND HIGH-FUNCTIONAL POLARIZING FILM AND STRETCHED LAMINATE USED FOR MANUFACTURING OF OPTICAL FILM LAMINATE INCLUDING THIN AND HIGH-FUNCTIONAL POLARIZING FILM

摘要

PROBLEM TO BE SOLVED: To provide a thin polarizing film with a high optical characteristic, and a manufacturing method thereof.SOLUTION: A thin and high-functional polarizing film is made of a PVA resin with alignment of dichroic material filmed on an amorphous ester-based thermoplastic resin substrate of continuous web, and has a thickness of 10 m or less. An optical characteristic value shown with single transmittance T and polarization degree P is within a range represented by an inequality expression of P-(10-1)×100 (however, T42.3) and P99.9 (however, T42.3).
