Tuning toner gloss with bio-based stabilizers

摘要

The disclosure describes a process to produce toner with tunable gloss levels comprising a stabilizer to freeze particle growth following aggregation, where the stabilizer does not chelate metal ions.

主权项

1. A method for making a toner comprising:
a) forming an emulsion comprising one or more amorphous resins, an optional crystalline resin, an optional wax, an optional colorant and an optional flocculant to form an emulsion comprising resin particles; b) aggregating said resin particles; c) optionally adding one or more resins to form a shell on said aggregated particles; d) adding a bio-based stabilizer in the absence of a chemical chelating agent to said aggregated resin particles to stop particle growth; and e) coalescing said aggregated resin particles to form toner particles; wherein said toner particles have a geometric number distribution or a geometric volume distribution of less than about 1.25.
