Patent number: 8247157Abstract: The present disclosure provides processes for increasing the shelf life and stability of resin emulsions suitable for use in forming toner particles. In embodiments, the pH of the resin emulsion is monitored, and a base is added as needed to maintain the pH of the emulsion at from about 6.5 to about 8. Maintaining the pH at from about 6.5 to about 8 prevents the degradation of the resin in the emulsion, including its molecular weight.Type: GrantFiled: December 9, 2008Date of Patent: August 21, 2012Assignee: Xerox CorporationInventors: Kimberly D.

Patent number: 8211600Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a magenta toner with a lower colorant loading in addition to a first magenta toner. In embodiments, the magenta pigmented particles may be magenta emulsion aggregation toners.
