Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous pigment dispersion composition that has excellent dispersibility of a carbon black pigment when used in inkjet ink and also has excellent scratch resistance, optical density, glossiness, and marker resistance. SOLUTION: The aqueous pigment dispersion composition is obtained by dispersing a self-dispersible carbon black pigment (A); a vinyl-modified epoxy ester resin (B) obtained when a polyvinyl group is bonded to at least a part of unsaturated groups of an unsaturated fatty acid-modified epoxy ester resin; and wax particles (C) in an aqueous medium (D).
