摘要:
The toner includes emulsion aggregation toner particles of a binder including a non-crosslinked styrene acrylate polymer, at least one colorant, at least one wax, and aluminized silica, wherein an amount of aluminum metal in the toner particles is from about 50 ppm to about 600 ppm. Such toner is able to provide a high level of gloss while maintaining a low minimum fixing temperature. The aluminized silica acts as a coagulant during the emulsion aggregation formation process of the toner.

Embodiments include a chemical toner composition having a first resin including a styrene vinyl copolymer and having a Tg of from about 46 to about 56° C., b) a second resin including a styrene vinyl copolymer having a Tg of from about 55 to about 65° C., c) a distilled wax having a heat of crystallization and a heat of enthalpy, both from about 1.0 to about 4.0 J/g for every weight percent of the wax used in the chemical toner composition, and wherein the wax has a peak melting point of from about 70 to about 99° C., and d) a colorant, wherein the chemical toner has a gloss of from about 30 to about 80 GGU.
摘要:
Toners are provided, which possess low melt properties capable of producing a low gloss finish. The toners include a core and a shell. The shell includes a crystalline resin. The core may include at least one amorphous resin, an optional crystalline resin, an optional wax, and an optional colorant.
摘要:
The present disclosure provides processes for producing polyester 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 compound, at the beginning of coalescence, which speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.
摘要:
A process for making toner particles is provided. In embodiments, a suitable process includes adding a defoamer to an emulsion utilized to form toner particles. Utilization of the defoamer allows for a reduction in the overall aggregation/coalescence cycle time and slurry viscosity, while producing a toner with improved GSDs, low coarse and target circularities.

Processes for producing toners are provided. The processes include determining the desired gloss for a given toner, and determining the desired amount of aluminum in the toner to obtain that gloss. Utilizing the processes of the present disclosure, the solids content of an emulsion utilized to produce such a toner, as well as the mixing speed utilized in the aggregation process and the temperature at which aggregation of the toner particles occurs, may then be selected to obtain toner particles possessing the desired amount of aluminum, and thus the desired gloss.
