Disclosed is a pigment dispersant represented by the following formula (1):
wherein X represents a hydrogen atom or an acylamino group; Y represents a specific aromatic group; Z represents a specific aromatic group or a C2-30 aliphatic, alicyclic or heteroalicyclic amine reaction residual group having at least one amino group; G represents a reaction residual group of at least one compound selected from C2-30 aliphatic, alicyclic and heteroalicyclic hydrocarbons each of which has at least one amino group; n is an integer of from 0 to 3; and when N stands for 0, Z represents a reaction residual group of a C2-30 aliphatic, alicyclic or heteroalicyclic polyamine having at least two amino groups. A pigment dispersion making use of the dispersant and a color filter produced from the pigment dispersion are also disclosed.
