Document Type and Number:
WIPO Patent Application WO/2022/249727
Kind Code:
A1
Abstract:
The present invention provides a double-sided adhesive sheet that is configured to have a limited thickness and that does not lift or peel from an adherend even when exposed to acidic liquids and alkaline liquids. Provided is a double-sided adhesive sheet having a thickness of 100 μm or less. This adhesive sheet has an acrylic adhesive agent layer containing an acrylic polymer. The adhesive sheet has a 180° peel strength F0 of 3.0 N/5 mm or greater with respect to a stainless steel sheet, as measured at a tensile speed of 300 mm/min. Additionally, the adhesive strength retention rate of the adhesive sheet after immersion in an acidic solution and the adhesive strength retention rate of the adhesive sheet after immersion in an alkaline solution are both 80% or greater.
