PROBLEM TO BE SOLVED: To provide a modified pigment product that can improve dispersibility and stability of dispersibility of the pigment in a composition and a formulation.SOLUTION: Various modified pigment products are described, which can be preferably dispersed in a variety of materials such as coatings, inks, toners, films, plastics, polymers, elastomers, and the like. The modified pigment is a pigment having attached groups, such as polymeric groups, by means other than adsorption. A modified pigment product is described comprising a pigment having attached at least one group comprising the formula of -X-[NIon]R. In the formula, X comprises an aromatic group or an alkyl group; NIon comprises at least one type of nonionic group; R represents hydrogen or comprises an aromatic group or an alkyl group; and p represents an integer of from 1 to 500. The modified pigment product is also described as a pigment having attached at least one alkylene oxide group or at least one polymeric group. In addition, other types of modified pigment products are described as well as their incorporation into inks, coatings, toners, films, plastics, polymers, elastomers, and the like. Methods for producing the modified pigment products are also described. |
