20080220359 | TONER PROCESSES - Disclosed herein are toner particles generated by emulsion/aggregation processes. The processes are conducted under conditions that shorten the time for coalescence and post-formation washing, thereby increasing efficiency of the processes as compared to conventional processes. | 09-11-2008 |
20080220362 | TONER COMPOSITIONS HAVING IMPROVED FUSING PROPERTIES - Image recording device comprising a development system including toner particles comprising a gel latex, a high Tg latex, a wax, and a colorant, and a fuser member, such as a fluoropolymer coated fuser member, which produces images having improved document offset, vinyl offset and half-tone rub properties. | 09-11-2008 |
20080295731 | REACTIVE INK COMPONENTS AND METHODS FOR FORMING IMAGES USING REACTIVE INKS - A reactive ink set including three mixtures of radically polymerizable monomers. A first mixture includes a peroxide, a second mixture includes a peroxide decomposition agent, and an optional third mixture that does not include a peroxide or a peroxide decomposition agent. The first mixture and the second mixture polymerize to form a solid ink on the substrate following jetting in the liquid state. | 12-04-2008 |
20090017393 | TONER COMPOSITIONS - Disclosed herein are emulsion aggregation toner particles having less than about 15 atomic percent oxygen in relation to a total atomic percent of 100 for all elements on the surface thereof. Such toner particles exhibit lower marks on print defects. | 01-15-2009 |
20090118545 | MICROREACTOR TECHNOLOGY TO BUCHWALD-HARTWIG AMINATION - A process for forming an arylamine compound, including reacting an arylamine and an aryl halide in the presence of a palladium ligated catalyst, a base and a suitable solvent in a microreactor. | 05-07-2009 |
20090142692 | LOW MOLECULAR WEIGHT LATEX AND TONER COMPOSITIONS COMPRISING THE SAME - Provided are a latex process and a toner process, both of which include the preparation of a latex having weight average molecular weight of from about 12×10 | 06-04-2009 |
20090263740 | TONER COMPOSITIONS - The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins 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 gel latex. | 10-22-2009 |
20100266948 | SOLVENT-FREE EMULSION PROCESS - A process for making a resin emulsion suitable for use in forming 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 a basic agent and water, and subjecting the resin, basic agent and water to acoustic mixing at a suitable frequency to form an emulsion of resin particles. In embodiments, the resin emulsion thus produced may be utilized to form a toner. | 10-21-2010 |
20100266949 | SOLVENT-FREE EMULSION PROCESS USING ACOUSTIC MIXING - 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. | 10-21-2010 |
20110070372 | Reactive Ink Components And Methods For Forming Images Using Reactive Inks - An ink set comprising 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 comprising 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. The components are each present in an amount relative to the other that provides a) early onset of gelation that accelerates polymerization, and b) an ink viscosity that is suitable for jetting from an ink jet printer. | 03-24-2011 |
