Patent number: 10613450Abstract: The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In particular, the crash cooling process involves the addition of a toner slurry having a temperature between 70° C. and 90° C. to an equivalent amount of cold water having a temperature between 5° C. and 20° C. Polyester and styrene acrylic toners as well as polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this cooling process results in an improvement to the amount of toner waste, thereby achieving a higher toner usage efficiency for an electrophotographic printing system.Type: GrantFiled: April 3, 2019Date of Patent: April 7, 2020Assignee: LEXMARK INTERNATIONAL, INC.Inventors: Kasturi Rangan Srinivasan, Rahel Bekru Bogale, Trent Duane Peter, Brian David Munson

Publication number: 20160363876Abstract: An overcoat layer and method to make an overcoated photoconductor drum of an electrophotographic image forming device using irradiation such as with electron beam (EB) or ultraviolet (UV) light is provided. The photoconductor drum is then cured using EB dose of between 10 and 100 kiloGrays (kGy), preferably between 20 and 40 kGys or UV irradiation with an exposure of between 0.1 and 2 J/cm2. The unique overcoat layer of the present invention is formed having a biphasic morphology comprised of a highly cured crosslinked phase and a second phase enriched in uncured material. The desired amount of uncured uncrosslinked material found in the second phase of the biphasic structure, is between 2-70 wt % range, with particularly good combination of long-life and electrical performance when present at the 5-50 wt % level, and the best performance at the 15-40 wt % level.Type: ApplicationFiled: August 23, 2016Publication date: December 15, 2016Inventors: MARK THOMAS BELLINO, GERALD HUGH CIECIOR, DOUGLAS JEFFREY HARRIS, WEIMEI LUO, BRIAN DAVID MUNSON, DAT QUOC NGUYEN, SCOTT DANIEL REEVES, TANYA YVONNE THAMES
