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.

摘要: A washing process using one or more ionic liquids (ILs) as a washing aid agent for toners, including toners produced using such ILs, such as, low melt toners, is provided. ILs are environmentally sound, green solvents that act to swell toner particle surfaces so that surface absorbed and adsorbed pollutants, such as, surfactants and other manufacturing reactants, can be effectively removed. The resulting toners have good charging, charge maintenance and RH sensitivity.
