Title:

ADHESIVE COMPOSITION AND ADHESIVE SHEET USING SAME

Document Type and Number:

WIPO Patent Application WO/2022/005139

Kind Code:

A1

Abstract:

The present invention relates to an adhesive composition containing a urethane oligomer, a dilution monomer, and a photoinitiator, wherein the weight ratio of heteroatoms in the dilution monomer is adjusted, and the permittivity and dissipation factor at 15 GHz of the adhesive layer having a thickness of 150 μm after curing are controlled to be in specific ranges. The adhesive composition according to the present invention may exhibit low dielectric properties suitable for the application to an image display device that requires a high-frequency band or is thinned.
