  • Patent number: 10719021
    Abstract: A toner and a toner process including providing at least one hybrid metallic toner component selected from the group consisting of hybrid metallic-latex particles, hybrid metallic-wax particles, hybrid metallic-colorant particles, and combinations thereof; contacting the at least one hybrid metallic toner component with one or more components selected from the group consisting of a latex polymer, a wax; and a colorant to form a blend; heating the blend at a temperature below the glass transition temperature of the latex polymer to form aggregated toner particles; adding a coalescing agent to the toner particles thereby coalescing the toner particles; and recovering the toner particles.
    Type: Grant

  • Patent number: 9372421
    Abstract: In an exemplary embodiment of the invention, a continuous process for rounding conventional toner particles includes forming a conventional toner particle slurry by mixing a dispersant and/or a liquid with dry toner particles, heating the conventional toner particle slurry to a first temperature beyond its glass transition temperature to form a coalesced toner particle slurry, quenching the coalesced toner particle slurry to a second temperature below the glass transition temperature after a residence time has elapsed, and recovering the quenched particle slurry at an outlet wherein the circularity of the conventional toner particles in the quenched toner particle slurry is from approximately 0.940 to 0.999 and the time frame for the heating, quenching and recovering steps is less than 20 minutes.
