Abstract
A process and system for continuously making a resin emulsion suitable for use in forming toner particles includes at least one micromixer for micromixing a resin mixture and aqueous phase to continuously produce an emulsion of a high solids content. The process comprises contacting a polyester resin possessing acid groups with a component selected from the group consisting of an organic solvent and a solvent inversion agent to form a resin mixture; neutralizing the resin mixture with a neutralizing agent; and subjecting the resin mixture to micromixing.
