METHOD FOR PRODUCING PHTHALOCYANINE COMPOUND PIGMENT MICRO-PARTICLE, PHTHALOCYANINE COMPOUND PIGMENT MICRO-PARTICLE OBTAINED BY THE SAME, INK-JET INK FOR COLOR FILTER, COLORING PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE RESIN TRANSFER MATERIAL COMPRISING THE SAME AND COLOR FILTER, LIQUID CRYSTAL DISPLAY DEVICE AND CCD DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a phthalocyanine compound pigment micro-particle of nano-meter size having excellent dispersion stability and fluidity and achieving high contrast and weather resistance, to provide an ink-jet ink for a color filter, a coloring photosensitive resin composition and a photosensitive resin transfer material comprising the same and to provide the color filter, a liquid crystal display device and a CCD device (charge coupled device) using the same.

SOLUTION: The method for producing the phthalocyanine compound pigment micro-particle is carried out as follows. A pigment solution prepared by dissolving a phthalocyanine compound pigment in a good solvent is mixed with a solvent compatible with the good solvent and providing a poor solvent for the pigment to deposit and produce the pigment and prepare a dispersion of the pigment micro-particle of the nano-meter size. In the process, a high polymer having≥1,000 mass-average molecular weight is contained in the dispersion.
