Document Type and Number:
WIPO Patent Application WO/2023/100861
Kind Code:
A1
Abstract:
The present invention provides a pressure-sensitive adhesive and/or an adhesive which can be more flexibly changed by an external stimulus at an arbitrary timing. Provided is a release liner-equipped pressure-sensitive adhesive sheet and/or adhesive sheet 10 comprising: a pressure-sensitive adhesive layer and/or adhesive layer 1 that includes the following component (a) and component (b); and a release liner 2. Component (a): a polymer that has, in the molecule thereof, a reversibly degradable bond which can be split by an external stimulus and then re-bond thereafter, and/or a compound capable of introducing the reversibly degradable bond into a polymer. Component (b): a compound that inhibits the re-bonding.
