摘要： A toner includes a polymeric resin, a colorant, and a small molecule crystalline aromatic monoester having a molecular weight less than 1,000 g/mol. The polymeric resin may be an amorphous resin and a mixture of the amorphous resin and the crystalline aromatic monoester may be characterized by a reduction in glass transition temperature from that of the resin and by the lack of a melting point for the crystalline aromatic monoester as determined by differential scanning calorimetry, the enthalpy of fusion for the crystalline aromatic monoester in the mixture being measured to be less than 10% of the enthalpy of fusion of the crystalline aromatic monoester in pure form. Furthermore, the toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner. Suitable crystalline aromatic monoesters may include 2-Naphthyl benzoate.

摘要： A toner includes a polymeric resin, optionally a colorant, and a small molecule crystalline diester having an aromatic core and a molecular weight less than 1,000 g/mol. The polymeric resin may be an amorphous resin and a mixture of the amorphous resin and the crystalline aromatic diester may be characterized by a reduction in glass transition temperature from that of the resin and by the lack of a significant solid to liquid phase transition peak for the small molecule compound as determined by differential scanning calorimetry, the enthalpy of fusion for the small molecule compound in the mixture being measured to be less than 10% of the enthalpy of fusion of the compound in pure form. Furthermore, the toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner.

摘要： A discrete nanostructure formed by a method comprising providing an aliphatic multi-block copolymer. The aliphatic multi-block copolymer includes at least one polyester block and at least one functionalized polycarbonate block. The aliphatic multi-block copolymer, a deprotonating agent and water are mixed to form an aqueous mixture. The aqueous mixture is maintained at a reaction temperature suitable to result in self-assembly of the multi-block copolymer into nanoparticles.
