Abstract
A phase inversion emulsification process includes dissolving a polyester resin and a styrene/acrylate resin in an organic solvent to provide a solution, neutralizing the solution with a neutralizing agent, forming an emulsion by adding water after the neutralizing step and removing a portion of the organic solvent from the emulsion to provide a latex.
