Abstract
A process for making a self-emulsifying granule suitable for use in forming latex emulsions includes contacting a resin with a solid or highly concentrated surfactant, a solid neutralization agent and water in the absence of an organic solvent to form a mixture, melt mixing the mixture, and forming self-emulsifying granules of the melt mixed mixture. 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.
