MANUFACTURING METHOD FOR PIGMENT NANOPARTICLE DISPERSION, COLORED PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE TRANSFERRING MATERIAL CONTAINING PIGMENT NANOPARTICLE, COLOR FILTER USING THOSE, LIQUID CRYSTAL DISPLAY APPARATUS, CCD DEVICE AND MANUFACTURING METHOD FOR INK JET INK FOR COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide an efficient manufacturing method for a pigment nanoparticle dispersion with a high dispersion stability, a colored photosensitive resin composition and a photosensitive transferring material containing the pigment nanoparticle obtained by it, a color filter using those, a liquid crystal apparatus and a CCD device and a manufacturing method for an ink jet ink for the color filter.;SOLUTION: In the manufacturing method for the pigment nanoparticle dispersion, when the organic pigment nanoparticle is precipitated/formed by mixing a pigment solution in which an organic pigment is dissolved in an organic acid or a solvent containing the organic acid with an organic solvent for precipitation, a polymer compound having a mass average molecular weight of 1,000-500,000 is contained in at least the pigment solution and the organic solvent for precipitation, and it is subjected to heating treatment at a temperature of 40°C or higher at dissolution of the pigment to precipitate/form the particle.;COPYRIGHT: (C)2008,JPO&INPIT
