    Abstract: Disclosed are a method of dispersing a pigment, a pigment dispersion, a coating composition comprising said pigment dispersion, an method of making a coating composition, and a method of improving the appearance of a coating composition. The pigment dispersion of the invention requires at least one pigment subjected to an action to decrease the average particle size of the pigment in the presence of an amine functional cellulose ester resin. The amine functional cellulose ester resins comprise at least one repeat unit of the structure:wherein R1, R2, and R3 are selected independently from the group consisting of hydrogen, R4C=O, andwherein at least one of R1, R2, and R3 is hydrogen, at least one of R1, R2, and R3 is R4C=O, and at least one of R1, R2, or R3 have the structureR4 is selected from the group consisting of C1-C20 alkyl groups, C1-C20 phenyl groups, C1-C20 napthyl groups, and C1-C20 alkenyl groups, L is a divalent linking group and R6 is selected from the group consisting of H and compounds having at least one secondary amine group, tertiary amine group, and mixtures thereof.
