20080199802 | TONER PROCESS - The present disclosure relates to a process for latex preparation comprising a first heating of a latomer mixture comprising at least one free radical polymerizable monomer to low conversion and then adding at least one alkylene anhydride; a second heating of the latomer mixture to low conversion; a third heating of the latomer mixture to form polymeric particles; and combining at least one amine with the polymeric particles. | 08-21-2008 |
20080213687 | TONER PROCESS - The present disclosure relates to a toner process comprising providing a resin miniemulsion comprising polymeric particles comprising at least one free radical polymerizable monomer compound and at least one alkylene anhydride; blending the miniemulsion with at least one colorant, at least one amine, and optionally at least one wax; heating the resulting mixture below or about equal to the glass transition temperature (Tg) of the resin emulsion; and heating the resulting mixture above or about equal to the glass transition temperature (Tg) of the resin emulsion. | 09-04-2008 |
20100183864 | FUSER TOPCOATS COMPRISING SUPERHYDROPHOBIC NANO-FABRIC COATINGS - In accordance with the invention, there are image forming apparatuses, fusing subsystems, and methods of making a member of the fusing subsystems. The method of making a member of a fusing subsystem can include providing a fuser member, the fuser member including a substrate and providing a dispersion including a plurality of carbon nanotubes, a stabilizer, a hydrophobic polymer, and a solvent, wherein the plurality of carbon nanotubes is selected from the group consisting of single wall carbon nanotubes and multiple wall carbon nanotubes. The method can also include applying the dispersion over the substrate to form a coated substrate and heating the coated substrate to form a hydrophobic composite coating such that a top surface of the fuser member has a water contact angle of at least about 120°. | 07-22-2010 |

20090117340 | Substrate, system and method for magnetic ink character recognition encoding - A document comprising a substrate with a surface having cellulose hydroxy groups, an adhesion promoter present on at least a first portion of the substrate surface, and a magnetic ink image formed over the first portion of the substrate surface. The adhesion promoter comprises a silane component including at least one amino functional group and at least one of a second type of functional group that is configured to bond with cellulose hydroxyl groups in the substrate. The magnetic ink image has a magnetic signal strength of at least 80%. A corresponding printing system and a method of printing also are disclosed. | 05-07-2009 |
20090162555 | Coating, system and method for conditioning prints - Disclosed herein is a xerographic print comprising a substrate having a printed image thereon comprising a low melt temperature toner, and a polyolefin wax coating formed over the printed image having a dry thickness in the range of about 0.5 to about 5 microns. The wax coating substantially prevents toner offset at temperatures up to at least | 06-25-2009 |
20130273471 | Low Melt Toner - Toners containing encapsulated crystalline resin have lower minimum fix temperatures without charge degradation. | 10-17-2013 |
