Document Type and Number:
WIPO Patent Application WO/2021/065923
Kind Code:
A1
Abstract:
In order to provide a polarizing film with an adhesive layer, which does not discolor the polarizing film even if exposed to a high humidity environment after bonding to the polarizing film, the present invention provides a polarizing film with an adhesive layer, which comprises a polarizing film and an adhesive layer that is arranged on at least one surface of the polarizing film, wherein: the adhesive layer is formed from an adhesive composition that contains an intramolecular hydrogen abstraction type initiator (A); and the polarizing film has a polarizer absorbance of 3.5 or more at a wavelength of from 300 nm to 400 nm as determined after being bonded with an adhesive layer that is formed from an adhesive composition that contains an intramolecular hydrogen abstraction type initiator and being left at rest at 25°C at 90% RH for two days.
