A pigment dispersion composition having a low water content is provided, which contains sharp organic pigment nanoparticles having a particle size distribution peak at a nano size having stable dispersibility. Furthermore, it provides the coloring photosensitive resin composition which is excellent in stability using the said pigment dispersion composition, and has high contrast, the inkjet ink for color filters, and the photosensitive resin transfer material. Furthermore, the present invention provides a color filter, a liquid crystal display device, and a CCD device having high contrast and excellent display characteristics.n n n An organic pigment nanoparticle and an organic solvent, the organic pigment nanoparticles having a primary particle size of less than 15nm proportion of less than 10%, the proportion of particles exceeding 60nm is less than 10%, the water content is 0.01% by mass It is%-5 mass%, The pigment dispersion composition characterized by the above-mentioned. |
