摘要:
Disclosed herein is printing system comprising a first printer configured to print a first set of data on a document, the first printer including a fuser employing fuser oil, and an in-line spray coater configured to deposit a wax coating on a portion of the document to repel or cover fuser oil. A corresponding method is also described. The method and system are useful for preparing MICR encoded documents such as checks.
摘要:
A laminating film and methods of use with xerographic prints. The laminating film comprises an adhesion promoter comprising a hydrolytic silane compound that imparts improved adhesion and which can be used in laminating applications conducted at high and as well as low temperature ranges.
摘要:
An adhesion promoter for a hot melt adhesive or a pressure sensitive adhesive prepared by admixing a hydrolytic silane compound with an aqueous buffer solution. The adhesive is able to bind at very low surface free energy substrates, such as Xerographic prints contaminated by silicone fuser oil. The hot melt adhesive maintains a substantially stable viscosity at temperature ranging from about 100° C. to about 200° C.
摘要:
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 70° C. A printing system and coating method also are disclosed. The prints, printing system and method are useful for making brochures and books that will be subjected to high temperatures, pressures, and/or humidity levels, such as manuals stored in automobile glove compartments.
摘要:
A composition includes at least one radiation curable (alkyl)acrylate-polyester oligomer, at least one photoinitiator, and at least one surfactant, wherein the composition has a viscosity of from about 50 cP to about 3000 cP at about 25° C., and a surface tension of from about 15 to about 40 dynes/cm at about 25° C.
摘要:
Toner particles comprise resin, wax and optionally colorants, and the wax is substantially excluded from the interior core of the toner particles. Processes for preparing such toner particles comprise providing an aqueous dispersion of resin particles and optionally colorants, mixing the aqueous dispersion in presence of a coagulant, aggregating to form particles, coalescing to form fused particles, and removing the fused particles from the aqueous dispersion. Wax dispersions can be added either after mixing or during aggregation, so that wax is excluded from the core of the toner particles.
摘要:
A process for depositing marking material onto a substrate which includes (a) providing a propellant to a head structure, the head structure having a channel therein, the channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, the propellant flowing through the channel to form thereby a propellant stream having kinetic energy, the channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material includes particles which include a resin and a colorant, the particles having an average particle diameter of no more than about 7 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein the particles are prepared by an emulsion aggregation process.
摘要:
A process for the fabrication of seamless substrates which comprises (1) providing a substrate with a release coating composition thereover; (2) depositing thereon by electrostatic powder spraying a polymer; (3) melting the polymer blend; and (4) subsequently permitting the melted blend to cool. Thereafter, layered photoconductive imaging members can be prepared by the application, for example, of a ground plane, a photogenerating layer, and a charge transport layer.
摘要:
An improved photoresponsive imaging member consisting essentially of a supporting substrate, a photogenerating layer, comprised of a photogenerating pigment optionally dispersed in an inactive resinous binder, an electron transporting layer comprised of derivatives of fluorenylidene methane dispersed in a resinous binder, and having incorporated therein a stabilizing amount of an aryl amine electron donating compound.
摘要:
The present teachings provide a fuser system member including a substrate and a topcoat layer disposed over the substrate. The topcoat layer comprises a fluoroelastomer cross-linked with amino silane wherein the topcoat is substantially free of copper oxide. A mercapto-functionalized oil is disposed on the topcoat layer.
