Patent number: 8435714Abstract: A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.Type: GrantFiled: June 25, 2010Date of Patent: May 7, 2013Assignee: Xerox CorporationInventors: Zhen Lai, Chieh-Min Cheng, Shigang Qiu, Emily L.

Patent number: 8342669Abstract: An ink set including at least two inks. A first ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and a peroxide initiator comprising a thermal free radical initiator. A second ink includes an optional colorant, a first multi-functional monomer, a second multi-functional monomer that is different from the first multi-functional monomer, and an amine activator having a catalyst which catalyzes the homolytic cleavage of the thermal free-radical initiator at low temperatures into radicals. The first ink is free of the amine activator and the second ink is free of the peroxide initiator. The first multi-functional monomer and the second multi-functional monomer accelerate reaction kinetics through a Trommsdorff effect.Type: GrantFiled: September 18, 2009Date of Patent: January 1, 2013Assignee: Xerox CorporationInventors: Santiago Faucher, Cheryl Lynn Pearce, Peter G.
