Abstract
A process is provided comprising forming a phase inversed resin emulsion comprising a resin, water, and an organic solvent, wherein the process excludes subjecting the phase inversed resin emulsion to an organic solvent removal technique, thereby retaining the organic solvent in the phase inversed resin emulsion. The phase inversed resin emulsion may be formed by dissolving a resin in an organic solvent to form a resin mixture; optionally, adding a neutralizing agent to the resin mixture to neutralize acid groups on the resin; and adding a sufficient amount of water to the resin mixture to emulsify and induce phase inversion in the resin mixture. Also provided are processes for preparing particles and processes for preparing toners utilizing the phase inversed resin emulsions.
