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.
