  • Compounds and methods of forming compounds useful as a toner
    Patent number: 8349531
    Abstract: Compounds and methods of forming compounds useful as a toner or toner precursor are disclosed. The compounds may include an aqueous dispersion, the dispersion including: (A) at least one thermoplastic resin; and (B) 0 to 5 weight percent of a stabilizing agent, based on the total weight of (A) and (B). The dispersion may have an average volume diameter particle size from about 0.05 to about 10 microns. A combined amount of the thermoplastic resin and the stabilizing agent may have an acid number of less than 25 mg KOH/g.
