ABSTRACT:
The present invention relates to amphipathic copolymeric binder particles that incorporate polymerizable crystallizable compounds chemically incorporated into a dispersible (D) portion and/or solvatable (S) portion of the copolymer. The invention also pertains to dry particulate electrophotographic toners incorporating an amphipathic copolymer comprising one or more polymerizable crystallizable compounds. Methods of making these dry electrophotographic toner particles, and methods of electrophotographically forming an image on a substrate using these toners, are also described.
