Title:
TRANSFER FILM, POLARIZING PLATE, IMAGE DISPLAY DEVICE, AND METHOD FOR PRODUCING POLARIZING PLATE
Document Type and Number:
WIPO Patent Application WO/2020/067291
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a transfer film that has excellent processing suitability as well as favorable transfer performance of a phase difference film; and a polarizing plate, an image display device, and a method for producing a polarizing plate. This transfer film has a provisional support, and a phase difference film provided on the provisional support so as to be separable, wherein: the phase difference film comprises a phase difference layer that is arranged, either directly or with an alignment film therebetween, on the provisional support; the phase difference layer is obtained by polymerizing a composition containing a liquid crystalline compound having a polymerizable group; and the phase difference layer meets both requirement 1 and requirement 2 if the phase difference layer is arranged directly on the provisional support, and the alignment film meets both requirement 1 and requirement 2 if the phase difference layer is arranged with the alignment film therebetween on the provisional support.
Requirement 1: Layer obtained by polymerizing a composition containing a non-liquid crystalline compound that has a trifunctional or higher polymerizable group
Requirement 2: Layer having a breakage/peeling load 0.4 N/25 mm or higher
