Document Type and Number:
WIPO Patent Application WO/2024/057558
Kind Code:
A1
Abstract:
The present invention provides a double-sided sticky sheet with release liners capable of suppressing, at a high level, deformation of sticky surfaces caused by release of the release liners. Provided is a double-sided sticky sheet with release liners, the sheet comprising a double-sided sticky sheet, a first release liner for protecting a first sticky surface of the double-sided sticky sheet, and a second release liner for protecting a second sticky surface of the double-sided sticky sheet. The double-sided sticky sheet has a colored sticky agent layer. The sticky agent layer also contains an acrylic polymer. Furthermore, the difference in peel strength between a peel strength R1 of the first release liner for the first sticky surface and a peel strength R2 of the second release liner for the second sticky surface is 0.07 N/50 mm or more. The storage elastic modulus at 0°C of the sticky agent layer is 0.95 MPa or less.
