Title:
DOUBLE-SIDED ADHESIVE SHEET, LAMINATE, AND METHOD FOR MANUFACTURING LAMINATE
Document Type and Number:
WIPO Patent Application WO/2023/157875
Kind Code:
A1
Abstract:
The present invention provides a double-sided adhesive sheet by which in a situation where constituent optical members of a display device having a touch panel are equipped with metallic electrically conductive parts, ion migration at the metallic electrically conductive parts can be suppressed when the optical members are pasted together, and changes in resistance value due to a hygrothermal environment and ultraviolet rays can be suppressed. Provided are: a double-sided adhesive sheet for pasting together a first adherend and a second adherend, both of which are constituent optical members of a display device having a touch panel, wherein the first adherend and/or the second adherend has metallic electrically conductive parts, and the adhesive sheet has a sulfur content of 50 mg/kg or less, a spectral transmittance of 30% or less at a wavelength of 380 nm, and a water vapor transmission rate of 400 g/m2/24 h or less or a water absorption rate of 1.0% or less; a laminate; and a method for manufacturing the laminate.
