摘要：
Provided are a processed pigment excellent in dispersibility and dispersion stability, a pigment-dispersed composition excellent in dispersibility and dispersion stability of a pigment that uses the processed pigment, a colored photosensitive composition using the pigment-dispersed composition, and a color filter having improved color properties that uses the colored photosensitive composition, in which a pigment is covered with at least one of a specific polymer compound selected from the following (SP-1) to (SP-3); (SP-1) A polymer compound having a heterocycle on a side chain, (SP-2) A graft polymer compound having a weight average molecular weight of from 1,000 to 100000, (SP-3) A polymer compound represented by the following formula (3-1), wherein, RC, RD, A1 and P1 respectively represent an organic linkage group, a single bond or a divalent organic linkage group, a monovalent organic group containing such as an organic dye structure, and a polymer skeleton.
