Title:
PRESSURE-SENSITIVE ADHESIVE SHEET
Document Type and Number:
WIPO Patent Application WO/2020/162331
Kind Code:
A1
Abstract:
Provided is a pressure-sensitive adhesive sheet that, after a curing treatment and even after exposure to high temperatures, can well separate from an object to which the sheet was adhered and can prevent adhesive residue when separated from said object. Provided is a pressure-sensitive sheet that includes a pressure-sensitive adhesive layer. The glass transition temperature of a polymer contained in the pressure-sensitive adhesive layer of the pressure-sensitive sheet is at least -63°C. The rate of decline in adhesion of the pressure-sensitive adhesive sheet after a heating-curing treatment is at least 17%.
