PROBLEM TO BE SOLVED: To provide a processed pigment excellent in dispersibility and dispersion stability, a pigment-dispersed composition excellent in dispersibility and dispersion stability of 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. SOLUTION: The processed pigment is covered with a polymer compound represented by the general formula (1), wherein R<SP>1</SP>represents a (m+n)-valent organic linkage group; R<SP>2</SP>represents a single bond or a divalent organic linkage group; A<SP>1</SP>represents a monovalent organic group containing at least one site selected from an organic dye structure, a heterocyclic structure, an acidic group, a group having basic nitrogen atom, an urea group, an urethane group, a group having coordinating oxygen atom, a 4C or more hydrocarbon group, an alkoxysilyl group, an epoxy group, an isocyanate group, a hydroxyl group and an ionic functional group; m represents 1-8, am n represents 2-9, m+n satisfying 3-10; and P<SP>1</SP>represents a polymer skeleton.
