More Information
Summary:The present disclosure relates to a polyester chemically produced toner composition including a core shell toner particle having special surface features and method to make the same. The special surface features on the outer surface of the core shell toner particle are created by the incorporation of a specially designed latex having styrene and acrylate monomers into the core of the toner particle wherein the latex in the core is tailored to be incompatible with the polyester resin(s) found in the core of the toner particle. The final ratio of the monomers in the latex to the surfactant in the latex is approximately 1:5. This ratio is key in maintaining a stable dispersion and is influenced by the particle size in the dispersion and surfactant chemistries.
