Toner processes for hyper-pigmented toners

摘要

The present embodiments relate to processes of preparing toner particles. More specifically, the processes produce toner particles having high pigment loadings and desired circularity. The processes include diluting the aggregated particulate mixture prior to coalescence.

主权项

1. A process comprising:
forming a particulate mixture of latex resin, wax and colorant; aggregating the particulate mixture such that the particulate has an average particle size of from about 3.5 to about 7 microns; diluting the mixture with a liquid after the step of aggregating, such that the diluted mixture contains a solid content of from about 8% to about 14% by weight based on the total weight of the diluted mixture; coalescing the diluted mixture to form toner particles; and recovering the toner particles, wherein the toner particles possess a circularity of from about 0.945 to about 0.998.
