Title:
ADHESIVE COMPOSITION, ADHESIVE SHEET, OPTICAL LAMINATE, IMAGE DISPLAY PANEL, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/085335
Kind Code:
A1
Abstract:
The adhesive composition provided herein contains, as a main component, a polymer (A) having a polyether structure, and further contains a conductive agent and a radical scavenger. When an adhesive sheet is formed from said adhesive composition, the adhesive sheet has a surface resistance value of at most 1×1010 Ω/□. Moreover, the adhesive sheet provided herein is formed from an adhesive composition containing a polymer (B) having a relative permittivity of at least 5.0 at a frequency of 100 kHz, and the content of formic acid in the adhesive sheet, which has been heated at 105ºC for 120 hours, may be at most 1,000 ppm on a mass basis.
