  • Patent number: 9804513
    Abstract: The present disclosure provides processes for producing toners by emulsion aggregation where the resulting toner particles have high pigment loadings and desired circularity. The methods include adding a metal, in embodiments a metal salt, at the beginning of coalescence, which surprisingly speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.

  • Patent number: 9644096
    Abstract: 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.

  • Patent number: 9557665
    Abstract: 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.
