    摘要: Processes for producing toners are provided. The processes include emulsion aggregation processes, whereby a reactive coalescent is utilized in the coalescence step to coalesce aggregated particles, thereby forming toner particles. The resulting toners may be highly pigmented, and may possess low melt characteristics.

    摘要: A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.
