  • Publication number: 20160091808
    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.
