PIGMENT DISPERSION AND INK COMPOSITION AND INK SET BOTH CONTAINING THE SAME

摘要

It is an object of the present invention to provide a pigment dispersion, an ink composition, and an ink set, enabling excellent glossiness, bronzing prevention, and ink composition storage stability to be realized. The present invention provides a pigment dispersion characterized by comprising at least a pigment, an aqueous medium, a copolymer resin between a hydrophobic monomer and a hydrophilic monomer, and a urethane resin, and also an ink composition characterized by containing at least the pigment dispersion and an aqueous medium, and an ink set characterized by comprising at least the ink composition.
