Title:
BONDING LAYER–COATED POLARIZING FILM, POLARIZING PLATE, AND PRODUCTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2023/167188
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide a bonding layer–coated polarizing film that has, at the surface thereof, a bonding layer that makes it possible to achieve excellent adhesion between a polarizing film and another member such as a support substrate. [Solution] According to the present invention, a bonding layer–coated polarizing film includes a polarizing film that comprises a polyvinyl alcohol resin and, at at least one surface of the polarizing film, a bonding layer that comprises a molecular bonding agent that bonds by chemical bonding. The bonding layer–coated polarizing film is characterized in that the molecular bonding agent includes a triazine derivative and in that the nitrogen (N) atom concentration at the surface of the bonding layer as measured by X-ray photoelectron spectroscopy is no more than 12.0 atm%.
