Patent 7416827 was granted and assigned to Xerox on August, 2008 by the United States Patent and Trademark Office.
Ultra low melt toner compositions with improved non-additive heat cohesion are disclosed. These toner compositions include toner particles comprising amorphous resins containing at least one unsaturated moiety, and when the toner particles are surface treated with a peroxy compound and optionally with a peroxy promoter compound, the surface of the toner particles is cross-linked to form a thin, robust shell. Processes for preparing the toner compositions are also described.
