<P>PROBLEM TO BE SOLVED: To provide a processed pigment in which formation of secondary aggregates is controlled and dispersibility is improved to be distributed in the state of primary particles even in a pigment having miniaturized particle size; to provide a processed pigment excellent in dispersion stability in which dispersed primary particles are stably maintained; to provide a pigment dispersed composition excellent in dispersibility and dispersion stability of pigment, and a colored photosensitive composition excellent in curability; to provide a color filter high in contrast; and to provide a liquid crystal display device and a solid-state imaging device equipped with a color filter. <P>SOLUTION: The processed pigment comprises a pigment and a high molecular compound for coating the processed pigment, wherein the high molecular compound has at least one selected from a group consisting of a hydroxyl group, an amide group, a carbamoyl group, and an urea group in a side chain and has a weight average molecular weight of 1,000-100,000. The processed pigment is used in the pigment dispersed composition, the colored photosensitive composition, the color filter, the liquid crystal display device and the solid-state imaging device. <P>COPYRIGHT: (C)2009,JPO&INPIT |
