Publication number: 20200319570Abstract: A method for producing a chemically prepared magenta toner composition according to one example embodiment includes combining and agglomerating a first polymer emulsion with a magenta colorant dispersion containing a single azo magenta pigment and a release agent dispersion to form toner cores. A borax coupling agent is added to the toner cores. A second polymer emulsion is combined and agglomerated with the toner cores having the borax coupling agent to form toner shells around the toner cores. The aggregated toner cores and toner shells are fused to form magenta toner particles. The single azo magenta pigment in the magenta pigment dispersion does not aggregate into clusters on the outer surface of the surface core.Type: ApplicationFiled: April 8, 2019Publication date: October 8, 2020Inventors: KASTURI RANGAN SRINIVASAN, ASHLEY SCHAFER GRANT, MICHAEL JAMES BENSING

Patent number: 10133203Abstract: A method for producing core shell toner for electrophotography according to one embodiment, includes surface treating the outer surface of a core shell toner particle with a alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons using a hydrolytic deposition process after the core shell toner particle is fully formed. This method results in the bonding of the alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons to the outer surface of the core shell toner particle. In an alternative method, the outer surface of the toner is surface treated with the alkoxysilane hydrocarbon solution and then fused to form toner particles. The alkoxysilane hydrocarbon surface treated core shell toner also can be mixed with magnetic carrier beads to form a developer mix to be used in a dual component development electrophotographic printer.Type: GrantFiled: January 17, 2018Date of Patent: November 20, 2018Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Danielle Renee Ashley, Ligia Aura Bejat, Michael James Bensing, Ashley Schafer Grant, Cory Nathan Hammond, Rick Owen Jones, John Joseph Kraseski, Jing X Sun

Patent number: 10133202Abstract: A chemically prepared toner composition according to one example embodiment includes a core including a first polymer binder, a colorant and a release agent; a shell that is formed around the core that includes a second polymer binder; and a borax coupling agent between the core and the shell and an alkoxysilane hydrocarbon or combination of different alkoxysilane hydrocarbons that are bonded to the outer surface of the shell using a hydrolytic deposition process. This successful alkoxysilane hydrocarbon surface treatment on the outer surface of the toner particle results in attaining a desirable charge stability in hot and humid environments and ultimately improving the quality of the toner, especially by reducing toner dusting, toner fuming and ultra-fine particles generation.Type: GrantFiled: January 17, 2018Date of Patent: November 20, 2018Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Danielle Renee Ashley, Ligia Aura Bejat, Michael James Bensing, Ashley Schafer Grant, Cory Nathan Hammond, Rick Owen Jones, John Joseph Kraseski, Jing X Sun

Patent number: 7923191Abstract: The present disclosure relates to chemically processed toner. The toner may be prepared by an emulsion aggregation method by forming a polyester dispersion wherein the polyester has an acid value of about 5 to about 50 and a particle size of about 50 to about 500 nanometers. The polyester dispersion may then be combined with a pigment and/or release agent dispersion wherein the pigment and/or release agent dispersion may contain a dispersant. This may then be followed by heating and recovering agglomerated toner particles wherein the toner particles may have a mean particle size of about 3 to about 15 microns and an average degree of circularity of between about 0.90 to about 1.0.Type: GrantFiled: July 26, 2007Date of Patent: April 12, 2011Assignee: Lexmark International, Inc.Inventors: Craig Michael Bertelsen, Ligia Aura Bejat, Michael James Bensing, John Joseph Kraseski, Matthew T.

Patent number: 7847790Abstract: A film interactive touchpad for control of home systems. A touchscreen defined by a glass panel and polyester film defines active areas responsive to contact. Multiple, customizable and interchangeable templates correspond with multiple levels of functionality and define input and control buttons corresponding to active areas of the touchpad. A display such as an organic light emitting diode (OLED) provides interactive, color feedback. The touchscreen has a hinged connection to the touchpad and is pivotable to an open position to permit insertion and removal of the overlay templates, and is surrounded by a trim ring dam to prevent moisture intrusion. A light sensor is provided for detecting the ambient light level and adjusting the intensity of a backlight for faceplates of any color.Type: GrantFiled: August 16, 2007Date of Patent: December 7, 2010Assignee: Elan Home SystemsInventors: Wilbur Bewley, Landrum Haddix, Sallie Tabb, David Moore, Richard B.
