Title:
ADHESIVE COMPOSITION, ADHESIVE SHEET, OPTICAL LAMINATE, IMAGE DISPLAY PANEL AND IMAGE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2023073210
Kind Code:
A
Abstract:
To provide an adhesive composition suitable for use in an optical laminate in environments where high temperatures should be considered while achieving a low surface resistance value and to provide an adhesive sheet formed from the adhesive composition.SOLUTION: There is provided an adhesive composition which comprises a polymer (A) having a polyether structure as a main component and further comprises a conductive agent and a radical scavenger. When an adhesive sheet is formed from the adhesive composition, the adhesive sheet has a surface resistance value of 1×1010 Ω/sq or less. In addition, the adhesive sheet is formed from an adhesive composition comprising a polymer (B) having a relative permittivity of 5.0 or more at a frequency of 100 kHz and the content of formic acid after heating at 105°C for 120 hours may be 1000 ppm or less on a mass basis.SELECTED DRAWING: Figure 1
