Title:
OPTICAL FILM AND OPTICAL LAMINATE CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2016/208548
Kind Code:
A1
Abstract:
The present invention provides a means for suppressing the occurrence of wrinkles in the processing step of an optical film, even if there is a significant difference in the high-temperature properties of the substrate and reflective layer of the optical film. The present invention pertains to an optical film having a substrate and a reflective layer, wherein the substrate and the reflective layer have an absolute value for the difference in storage modulus (E') at 150°C (measurement conditions: conforming with JIS K7244 - 1:1998, tensile mode, heating rate 5°C/min, frequency 10Hz) is at least 0.05GPa, and the loss tangent (tanδ) at 150°C) (measurement conditions: conforming with JIS K7244-1:1998, tensile mode, heating rate 5°C/min, frequency 10Hz) is 0.12-0.20.
