Document Type and Number:
WIPO Patent Application WO/2022/045131
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an adhesive agent composition, an adhesive agent layer, and an adhesive sheet which exhibit superior conformability and workability, and are suited for producing emissive display devices such as mini/micro LED display devices which have an improved contrast and a function for preventing reflection from metallic wiring and the like. The present invention provides: an adhesive agent composition comprising a colorant and a polymer (A) having a benzophenone structure in a side chain thereof, or comprising a colorant and a mixture of monomer components that constitute the polymer (A) having a benzophenone structure in a side chain thereof or a partial polymer of the mixture of monomer components that constitute the polymer (A) having a benzophenone structure in a side chain thereof, wherein the maximum value for the transmittance of wavelengths in the range of 200-400 nm is greater than the maximum value for the transmittance of wavelengths in the range of 400-700 nm; a photocurable adhesive agent layer which is an adhesive agent layer formed from the cured product of the adhesive agent composition, wherein the cured product retains the benzophenone structure of the polymer (A) having a benzophenone structure in a side chain thereof; and a photocurable adhesive sheet that has the photocurable adhesive agent layer.
