    摘要: An emulsion aggregation toner composition is disclosed that includes toner particles with at least one small crystalline molecule, such as a trans-cinnamic diester, at least one amorphous resin, optional waxes, coagulants, pigments, and combinations thereof. In other embodiments, the small crystalline molecule is biodegradable and can be made using raw materials derived from renewable resources. Such small crystalline molecules are also compatible with amorphous binder resins, to provide toner compositions with reduced minimum fusing temperatures without sacrificing electrical performance. Processes for preparing emulsion aggregation toner compositions are also described.
