Patent number: 9625840Abstract: A process for making a latex emulsion suitable for use in a toner composition includes co-emulsifying a bio-based resin with an insoluble component, such as a pigment or wax, whereby the resin encapsulates the insoluble component. The resulting latex, including the insoluble component encapsulated in the resin, may then be utilized to form a toner. The insoluble component may thus be included in toner particles, which might otherwise be difficult to achieve, using emulsion aggregation processes.Type: GrantFiled: May 12, 2015Date of Patent: April 18, 2017Assignee: Xerox CorporationInventors: Ke Zhou, Kimberly D Nosella, Guerino Sacripante, Sonja Hadzidedic

Patent number: 9239529Abstract: Processes for producing toners are provided. The processes include determining the desired gloss for a given toner, and determining the desired amount of aluminum in the toner to obtain that gloss. Utilizing the processes of the present disclosure, the solids content of an emulsion utilized to produce such a toner, as well as the mixing speed utilized in the aggregation process and the temperature at which aggregation of the toner particles occurs, may then be selected to obtain toner particles possessing the desired amount of aluminum, and thus the desired gloss.Type: GrantFiled: December 20, 2010Date of Patent: January 19, 2016Assignee: Xerox CorporationInventors: Kimberly D. Nosella, Daryl W. Vanbesien, Allan K. Chen, Sonja Hadzidedic
