Abstract:
A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one amorphous polyester resin with an organic solvent to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, separating the solvent from water, and recycling the solvent from the resin mixture for utilization in a subsequent phase inversion emulsion process.
