Disclosed is a colorant comprising both a pigment component and a dye component that exhibits improved saturation and good water and light resistance. The polymer colorant of the present invention can include a pigment having a polymer covalently bonded thereto, and a dye covalently bonded to the polymer. A dispersant can be covalently bonded to at least one of the pigments, polymers, and dyes. By including both a pigment component and a dye component, the polymeric colorant can achieve improved saturation, water resistance, and light resistance. The dye component and the pigment component can be substantially the same color or different colors depending on the desired appearance. While the polymeric colorants of the present invention are well suited for inclusion in inkjet compositions, the polymeric colorants are also suitable for many other applications.
