[PROBLEMS] To provide: (1) a pigment dispersant having excellent dispersing/stabilizing properties; (2) a curable colored composition which contains the pigment dispersant and which, when used as an actinic-energy-ray-curable colored composition, retains intact sensitivity, and which, when used as a pattern-forming composition, is excellent in developability and suitability for patterning, and which, when used as a thermosetting colored composition, gives a cured film having excellent properties; and (3) a composition suitable for use in color filters. [MEANS FOR SOLVING PROBLEMS] The pigment dispersant, which is curable, contains a compound (a), as an essential component, which has two or more ethylenically unsaturated groups, a tertiary amino group, and an aromatic group and contains no acid group.
