<P>PROBLEM TO BE SOLVED: To provide modified pigment products which are capable of improving the dispersibility and dispersion stability of the pigment in compositions and formulations. <P>SOLUTION: Various modified pigment products are described which are preferably capable of being dispersed in a variety of materials such as coatings, inks, toners, films, plastics, polymers and elastomers. The modified pigments are pigments having attached groups, such as polymeric groups, onto the pigment by means other than adsorption. A modified pigment product is described comprising a pigment having attached at least one group comprising the formula: -X-[NIon]pR (wherein: X comprises an aromatic group or an alkyl group; NIon comprises at least one type of non-ionic group; R represents hydrogen or comprises an aromatic group or an alkyl group; and p represents an integer of from 1 to 500). Modified pigment products are also described comprising 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 of making the modified pigment products are also described. <P>COPYRIGHT: (C)2012,JPO&INPIT |
