METHOD OF PRODUCING ORGANIC PIGMENT NANOPARTICLES, ORGANIC PIGMENT NANOPARTICLES THUS OBTAINED, PIGMENT DISPERSION, COLORED PHOTOSENSITIVE RESIN COMPOSITION, INKJET INK FOR COLOR FILTER, AND PHOTOSENSITIVE RESIN TRANSFER MATERIAL, EACH CONTAINING THE SAME, AND COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE, EACH PREPARED BY USING THE SAME

摘要

PURPOSE: A manufacturing method of an organic pigment nanoparticle, the organic pigment nanoparticle, a pigment dispersant including thereof, a colored photosensitive resin composition, an ink jet ink for a color filter a photosensitive resin material, the color filter and a liquid crystal display are provided to effectively mass-produce the organic pigment nanoparticle. CONSTITUTION: A manufacturing method of an organic pigment nanoparticle comprises the following: mixing a first good solvent with an organic pigment solution, and a first poor solvent to prepare a dispersion A; mixing a second good solvent with an organic material solution, and a second poor solvent to prepare a dispersion B; mixing the dispersion A and the dispersion B and enhancing the solubility a low molecule organic material higher than the organic pigment.
