Title:
PRESSURE-SENSITIVE ADHESIVE SHEET, PRODUCTION METHOD THEREFOR, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/184155
Kind Code:
A1
Abstract:
Provided is a pressure-sensitive adhesive sheet which need not be photocured after application to adherends and which can combine irregularity-absorbing properties with dimensional stability. The pressure-sensitive adhesive sheet (5) is a sheet formed from a pressure-sensitive adhesive comprising a base polymer having a crosslinked structure and has a shear storage modulus at 25°C of 0.16 MPa or greater and a loss tangent at 70°C of 0.25 or greater. The pressure-sensitive adhesive sheet has a glass transition temperature of preferably -3°C or lower. The pressure-sensitive adhesive has a gel content of preferably 30-80% and a polymer content (nonvolatile content) of 95% or higher.
