| titleOfInvention | Polymeric dispersants used for aqueous pigmented inks for ink-jet printing |
| abstract | The present invention relates to graft copolymers, useful as dispersants in ink jet ink compositions, which comprise two structurally distinct segments: a hydrophilic segment and a hydrophobic segment. The preferred hydrophilic segment is comprised preferably of a methacrylic acid polymer, or a copolymer thereof with another monomer, such as styrene sulfonic acid. The preferred hydrophobic segment comprises a polymer or copolymer containing electron rich functional groups comprised of a plurality of methacrylate derivatized monomers, preferably a methacrylate ester monomer, or a substitited methacrylate ester monomer (a methacrylate ester where the alkyl group is replaced with a siloxyl substituent, and oligomeric siloxane). The present invention also relates to aqueous ink compositions which include the polymeric dispersants of the present invention. A further embodiment of the present invention comprises a polymer comprising a monomeric hydrophobic head and a polymeric tail. In a preferred embodiment, the monomeric hydrophobic head is (ethylene glycol) 2, 4,6-tris-(1-phenylethyl)phenyl ether. |
