Abstract
Disclosed is a pigment dispersant represented by the following formula (1): ##STR1## wherein X represents a hydrogen atom or an acylamino group; Y represents a specific aromatic group; Z represents a specific aromatic group or a C.sub.2-30 aliphatic, alicyclic or hetero-alicyclic amine reaction residual group having at least one amino group; G represents a reaction residual group of at least one compound selected from C.sub.2-30 aliphatic, alicyclic and hetero-alicyclic hydrocarbons each of which has at least one amino group; n is an integer of from 0 to 3; and when N stands for O, Z represents a reaction residual group of a C.sub.2-30 aliphatic, alicyclic or hetero-alicyclic 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.
