  • Curable toner compositions and processes
    Patent number: 9594319
    Abstract: An emulsion aggregation toner composition includes toner particles including: an unsaturated polymeric resin, such as amorphous resins, crystalline resins, and combinations thereof; an optional colorant; an optional wax; an optional coagulant; and a photoinitiator. By optimizing the particle size of the emulsion, the aggregant concentration utilized in the emulsion aggregation process, and the solids content of the emulsion, toners may be produced capable of generating images with non-contact fusing that have high gloss.
