Document Type and Number:
WIPO Patent Application WO/2021/131504
Kind Code:
A1
Abstract:
[Problem] To provide a novel optical multilayer body which is suppressed in decoloration at an end portion of a polarizer under high temperature high humidity conditions. [Solution] An optical multilayer body which comprises a polarizer and a selectively light absorbing adhesive layer that is stacked on the polarizer, wherein: iodine is adsorbed and oriented on the polarizer; the polarizer has a boron content of 5.0% by mass or less; and the selectively light absorbing adhesive layer is formed from an adhesive composition that contains a selective light absorbent, while having an absorbance of from 0.1 to 1.6 at the wavelength of 410 nm.
