PROCESSES FOR PRODUCING POLYESTER LATEXES VIA SOLVENT-FREE EMULSIFICATION

摘要

A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one amorphous polyester resin with a viscosity reducing additive in the absence of an organic solvent to form a resin mixture either via an extruder or batch process, and adding a surfactant, neutralizing agent, and deionized water to the resin mixture.
