Title:
FLUORESCENT DYE-CONTAINING NANOPARTICLES AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/234721
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: fluorescent dye-containing nanoparticles that are capable of emitting high brightness light with excellent reproducibility, and that contain a dye that hardly elutes in an alkaline solvent or an organic solvent. The fluorescent dye-containing nanoparticles contain a thermosetting resin and a fluorescent dye, and are each characterized by having, in a range from the outermost surface to the central part thereof, a region where the content percentage of the fluorescent dye is within a range of 0.01-5.0 mass% with respect to the amount of the fluorescent dye in the particle overall.
