Zusammenfassung:The present invention provides an amphipathic copolymer comprising one or more S portions and one or more D portions, the amphipathic copolymer having a chromophore covalently bonded thereto via a urethane, urea or amide linkage. These copolymers provide exceptionally useful components in toner compositions, because they provide easily prepared color-imparting particles that provide excellent color rendition. Corresponding toner compositions, methods of making an amphipathic copolymer, and liquid electrophotographic toner compositions are also disclosed.
