Abstract:
A process for making a latex emulsion including contacting at least one amorphous polyester resin with at least two organic solvents to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and separating the solvent from water. Further, the process is carried out above the resin Tg for making the latex, which drives the latex particle size under 100 nm, where toners made from the latex show improved charging performance.
