    Abstract: 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.

    Abstract: The present disclosure relates to a toner design for a clear UV red fluorescence toner having a high lanthanide complex pigment loading, including methods of making the fluorescence toner using a saccharide or a sugar acid to avoid complexation of lanthanide ions from the pigment, with lower aggregation and coalescence temperatures in the preparation of toner particles, where the particles exhibit a narrow size distribution and good xerographic performance.
