    摘要: A process for making toner particles comprising: (a) forming an emulsion comprising a disperse phase including a first aqueous composition and a continuous phase including molten one or more ingredients of a toner composition, wherein there is absent a toner resin solvent in the continuous phase; (b) performing a phase inversion to create a phase inversed emulsion comprising a disperse phase including toner-sized droplets comprising the molten one or more ingredients of the toner composition and a continuous phase including a second aqueous composition; and (c) solidifying the toner-sized droplets to result in toner particles.

    摘要: A process for preparing a toner, includes solvent flashing wax and resin together to emulsify the resin and wax to a sub-micro size; mixing the wax and resin emulsion with a colorant, and optionally a coagulant to form a mixture; heating the mixture at a temperature below a glass transition temperature of the resin to aggregate the resin, colorant, and wax, to form aggregated particles; heating the aggregated particles and coalescent agent at a temperature above the glass transition temperature of said resin, to coalesce the aggregated particles to form toner particles, optionally cooling the mixture; and isolating the toner particles.
