A pigment dispersion that can be easily dispersed even with a pigment having poor dispersion stability, such as an organic pigment or carbon black, has a high affinity for various dispersion media, and is stable for a long period of time. Provided are a pigment dispersant and a pigment dispersion composition using the same. A pigment dispersant represented by the general formula (1). (1) (A is a polymerizable functional group, R 1 and R 2 are each independently a single bond, a divalent hydrocarbon group having 1 to 16 carbon atoms, X 1 is a single bond, —O—, —CO. -, - CO-O-like, R 3 to R 10 are each independently H, halogen atom, a hydroxyl group, B is a polymer chain) [Selection figure] None |
