Abstract: The present disclosure provides processes for producing toners by emulsion aggregation where the resulting toner particles have high pigment loadings and desired circularity. The methods include adding a metal, in embodiments a metal salt, at the beginning of coalescence, which surprisingly speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.

Abstract: The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.
