Title:
ADHESIVE COMPOSITION, ADHESIVE SHEET MANUFACTURED THEREFROM, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/080599
Kind Code:
A1
Abstract:
Embodiments of the present invention provide an adhesive composition. Provided is an adhesive composition comprising an acrylic copolymer comprising a repeating unit derived from a first acrylic monomer, wherein the first acrylic monomer contains a sulfur atom and the refractive index of a homopolymer is 1.53 or higher. Since an adhesive layer formed from the adhesive composition has a low glass transition temperature and a high refractive index, a separate high-refractive-index pattern layer cannot be included in an image display device.
