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: Described herein is a method for manufacturing a low gloss toner. The method includes mixing a resin, a colorant and an optional wax in water to form an emulsion. The emulsion is heated in the presence of a polyion coagulant to form a plurality of aggregated particles, wherein the heating is to a temperature of below the glass transition temperature of the resin. Trisodium citrate dihydrate is added to the heated emulsion in amount of from 0.4 weight percent to about 1.0 percent by weight based on of a total weight of reagents while stirring, wherein the trisodium citrate dihydrate. The aggregated particles are heated to a temperature above the glass transition temperature of the resin to form toner particles have a volume average particle diameter of from 4.3 microns to 4.9 microns.

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.
