A method of forming a modified pigment comprising a pigment having attached at least one polymeric group is described. In one embodiment, a polymer, a pigment, a linking agent, and an optional activating agent are combined, and the linking agent is reacted with the polymer and the pigment to form the modified pigment. In another embodiment, a polymer melt is formed comprising a polymer and an optional plasticizer, and the polymer melt, a pigment, and an optional activating agent are combined, in any order, under high-intensity mixing conditions. Also disclosed are modified pigments having specific properties and inkjet ink compositions comprising them.
