Title:
POLARIZING FILM WITH PRESSURE-SENSITIVE-ADHESIVE LAYER, IMAGE DISPLAY PANEL, METHOD FOR MANUFACTURING IMAGE DISPLAY PANEL, AND PRESSURE-SENSITIVE-ADHESIVE LAYER
Document Type and Number:
WIPO Patent Application WO/2022/024579
Kind Code:
A1
Abstract:
The present invention provides a polarizing film with a pressure-sensitive-adhesive layer, comprising a pressure-sensitive-adhesive layer which is durable in a high-temperature environment and in which reworkability after preheating is maintained even when the pressure-sensitive-adhesive layer is bonded to an electroconductive layer. This polarizing film with a pressure-sensitive-adhesive layer comprises a polarizing film and a pressure-sensitive-adhesive layer formed from a pressure-sensitive-adhesive composition. The pressure-sensitive-adhesive composition includes a compound (C) having an acidic group or an acid anhydride group, and a polyether compound (D). In the pressure-sensitive-adhesive layer, the adhesion strength P85 is 10.0 N/25 mm or less, and the adhesion strength P105 is greater than 10.0 N/25 mm.
