Title:
COLOR FILTER INKJET INK COMPOSITION, CURED MATERIAL, PHOTOTRANSFORMATION LAYER, AND COLOR FILTER
Document Type and Number:
WIPO Patent Application WO/2022/181430
Kind Code:
A1
Abstract:
Provided is a color filter inkjet ink composition from which can be formed a color filter pixel part having excellent external quantum efficiency, and that has excellent re-dispersibility, despite the composition containing luminescent nanocrystal particles and light-scattering particles. A color filter inkjet ink composition containing luminescent nanocrystal particles, an organic ligand capable of bonding with the surfaces of the luminescent nanocrystal particles, light-scattering particles, a polymer dispersant, and a photopolymerizable compound, the content of the organic ligand being 15-50 parts by mass with respect to 100 parts by mass of the luminescent nanocrystal particles, and the content of the polymer dispersant being 3-15 parts by mass with respect to 100 parts by mass of the light-scattering particles.
