Document Type and Number:
WIPO Patent Application WO/2020/017555
Kind Code:
A1
Abstract:
The present invention addresses the problem of enhancing the non-curling properties of a pressure-sensitive adhesive sheet having post-curability and processability. The present invention relates to the pressure-sensitive adhesive sheet described in claim 1, which includes a pressure-sensitive adhesive layer obtained by semi-curing a pressure-sensitive adhesive composition, the pressure-sensitive adhesive sheet satisfying physical properties (1) and (2) after the pressure-sensitive adhesive layer is post-cured by irradiation with actinic rays so as to result in an integrated quantity of light of 3,000 mJ/cm2. Physical property (1): To have an elongation at break, as measured by a tensile test at a pulling speed of 10 mm/min, of 300% or greater. Physical property (2): To have a probe tack value, as measured at 23°C under given measurement conditions, of 1.0 N/5 mmϕ or less.
