Title:
ADHESIVE SHEET, OPTICAL MULTILAYER BODY AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/106095
Kind Code:
A1
Abstract:
The present invention provides an adhesive sheet which is formed from a photocurable composition, and which has a sufficiently low surface resistivity, while being suitable for increasing the value of anchoring strength to an optical film. This adhesive sheet 1 is formed from a photocurable composition that contains a monomer group and/or a partial polymer of the monomer group. This adhesive sheet 1 satisfies at least one of the following requirements: (i) the photocurable composition contains an ionic compound C that has a functional group F which is reactive with the monomer group and/or the partial polymer; and (ii) in the photocurable composition, the partial polymer and an ionic compound C are bonded via a covalent bond. With respect to this adhesive sheet 1, the ratio R1 is 2.0 or less as determined by a test in which a corona treatment is performed.
