Patent number: 8455171Abstract: The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.Type: GrantFiled: May 31, 2007Date of Patent: June 4, 2013Assignee: Xerox CorporationInventors: Robert D. Bayley, Timothy L. Lincoln, Kevin F. Marcell, Grazyna E. Kmiecik-Lawrynowicz, Maura A. Sweeney, Daniel W. Asarese, Chieh-Min Cheng, Zhen Lai

Patent number: 8383310Abstract: The present disclosure relates to a binder resin system suitable for use in forming toner compositions. In embodiments, the binder resin system includes at least one amorphous resin, at least one crystalline resin, and at least one fatty acid salt. The presence of the fatty acid salt reduces plasticization which may otherwise occur upon combining the amorphous and crystalline resins, thereby increasing the glass transition temperature of the binder resin, as well as any toner produced with such binder resin. Toners produced with the disclosed binder resin may also include one or more optional ingredients such as optional colorants, optional waxes, and combinations thereof.Type: GrantFiled: April 27, 2010Date of Patent: February 26, 2013Assignee: Xerox CorporationInventors: Mark E. Mang, Timothy L. Lincoln
