    Patent number: 8618192
    Abstract: A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one amorphous polyester resin with a viscosity reducing additive in the absence of an organic solvent to form a resin mixture either via an extruder or batch process, and adding a surfactant, neutralizing agent, and deionized water to the resin mixture.

  • Toner compositions
    Patent number: 8338069
    Abstract: The present disclosure provides processes for producing toner particles, and toner particles produced by such processes. The processes of the present disclosure combine melt-mixing and grinding of toner components to produce toner particles, followed by a coalescing treatment which provides toner particles having desirable spherical properties.

    Inventors: Brian J. Andaya, Timothy L. Lincoln, D. Paul Casalmir, Joseph L. Leonardo, Anthony Uttaro, Jr.
  • Self emulsifying granules and solvent free process for the preparation of emulsions therefrom
    Patent number: 8211604
    Abstract: A process for making a self-emulsifying composite suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralizing agent in the absence of water and an organic solvent to form a mixture, melt mixing the mixture, and forming a self-emulsifying composite of the melt mixed mixture such as a granule. Self-emulsifying granules are also provided and configured to form a latex emulsion when added to water, which may then be utilized to form a toner.
    Type: Grant
