Abstract
A process includes dissolving a styrene/acrylate resin in an organic solvent to form a first solution, dissolving at least one polyester resin in the first solution to form a second solution, neutralizing the second solution with a base to provide a neutralized solution, and adding a sufficient amount of water to the neutralized solution to form an emulsion. A latex particle includes a polyester resin and a styrene/acrylate resin dispersed within the latex particle, the surface of the latex particle is substantially the polyester resin. A toner includes a plurality of toner particles prepared from a latex, the particles of the latex including a polyester resin and a styrene/acrylate resin dispersed within each latex particle, the surface of each latex particle is substantially the polyester resin.
