Title:
QUANTUM DOT-CONTAINING COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2024/075580
Kind Code:
A1
Abstract:
The present invention is a quantum dot-containing composition obtained by dispersing quantum dots which emit fluorescence as a result of excited light in a resin composition, said quantum dot-containing composition being characterized in that said quantum dots have a ligand which is positioned on the surface thereof, and a surface-coating layer which is bonded to the ligand and contains a siloxane bond, and in that the surface-coating layer has: a substituent group which is present in a polymer contained in the resin composition; and/or a substituent group which can be polymerized with the polymer contained in the resin composition; and/or a compound which has a skeleton structure which is identical to that of said polymer. As a result, it is possible to provide: a quantum dot-containing composition which retains the properties of the quantum dots while improving stability and improving compatibility with high-polarity solvents and photosensitive resin compositions.
