Abstract
Amphipathic copolymers are provided comprising one or more S portions and one or more D portions. The copolymers have 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.
