摘要:
A process for making toner particles is provided. In embodiments, a suitable process includes adding a washing aid agent to toner particles at the time of washing the toner particles prior to their drying and recover. The washing aid agent assist in the removal of ionic species, including surfactants and ions that are part of the emulsion aggregation process, from the resulting toner particles. Utilization of the washing aid agent produces toner particles having improved charging characteristics.

摘要:
The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the gel latex.
摘要:
Processes for producing toner are provided which utilize reactive coalescing agents in forming the toner particles, as well as toners produced by such processes.
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:
Copolymer encapsulated wax particles and their use in forming toner compositions having particles with a desired circularity and size are provided.
摘要:
Processes for preparing toner compositions used with electrostatographic imaging members. The processes utilize screw extruders to facilitate continuous dispersion and aggregation of toner components, such as color pigments and wax. The continuous dispersion produces the toner components with more control and better product yield. The products produced are also improved in quality.
摘要:
A process and system for making a resin emulsion suitable for use in forming toner particles including a silicone free anti-foam agent to control foam during formation of a polyester dispersion.
