摘要:
Toner fusing rolls having an oil barrier layer composed of a substrate coated with a fluorocarbon-silicone polymeric composition which is obtained by concurrently curing a fluorocarbon copolymer, a nucleophilic fluorocarbon-curing agent and a heat-curable polyfunctional poly(C.sub.1-6 alkyl)phenylsiloxane polymer.
摘要:
An image forming apparatus includes a source of at least one intermediate sheet which is preferably both thermally and electrically conductive. Toner images are transferred from one or more image members to the intermediate sheet under conditions of raised temperature and preferably with the assistance of an electric field. The toner image on the intermediate sheet is then overlaid with a receiving sheet and a combination of heat and pressure transfers and fuses the toner image to the receiving sheet in a single step, preferably while the sheets move at full machine speed. The sheets may then be slowed down or stopped, but are maintained together until cool at which point they are separated and the intermediate sheet fed back to the source of intermediate sheets. The image forming apparatus is particularly useful in creating multicolor toner images with small toners.
摘要:
Toner fusing members coated with melamine-cured phenolic polysfloxanes compositions are obtained. Such a phenolic polysiloxane is obtained by hydride-addition of a hydride-substituted polysiloxane with an alkenyl substituted phenol.
摘要:
A two-component, dry electrostatic developer composition containing toner particles and coated-carrier particles is disclosed. The toner contains a binder polymer and a phosphonium, arsonium or stibonium charge-control agent dispersed in the toner binder. The carrier is coated with a fluoropolymer. The resulting developer exhibits reduced toner throw-off and other disclosed advantages.
摘要:
An inkjet printing system contains an inkjet printer loaded with a recording element comprising a support and an ink receiving layer containing:a) fusible polymeric particles; andb) a water soluble block copolymer having ethylene oxide and propylene oxide segments, the copolymer exhibiting a Draves wetting coefficient, for a 0.1 wt % solution in water at 25° C., of not more than 360 seconds. An inkjet printing method and an inkjet recording medium are also contemplated.
摘要:
An inkjet recording element comprising a support having thereon in order, from top to bottom, an upper fusible, porous layer comprising fusible polymeric particles, which particles comprise a thermoplastic polymer with reactive functional groups, the inkjet recording element further comprising a lower crosslinker-containing layer in which a polyfunctional compound has complementary reactive functional groups capable of crosslinking the reactive functional groups on the thermoplastic polymer under fusing. Optionally, an ink-carrier-liquid receptive layer is present between the fusible, porous layer and the support. Also disclosed is a method of inkjet printing on the element.

摘要:
A method of fusing an electrostatographic colored toner image on a transparent support to provide a projection viewable color transparency exhibiting excellent color clarity. The support comprises a polymer layer bearing the color toner image. The toner used to form the image has a loss tangent of 1.5 or less while the polymer that forms the layer bearing such image has a higher loss tangent. The transparent element is subjected to fusing in three distinct zones; a fusing zone where it is contacted with a fusing member, a cooling zone where contact with the fusing member is maintained and the toner image is cooled and a release zone where the toner image is released from the fusing member at a temperature where no toner image or polymer layer offset occurs.
摘要:
Small particle toner images carried on an image member are transferred to thermally conductive intermediate by heating the intermediate in the presence of an electrical field urging transfer. The intermediate is heated to a temperature sufficient to sinter the toner particles at least when they touch the intermediate and other toner particles, but insufficient to damage the image member or cause the toner to stick to the image member. The toner image is transferred from the intermediate to a receiving sheet, which step can include sufficient heat and pressure to fix the image to the receiving sheet.
摘要:
Toner fusing members coated with melamine-cured polyester-amide compositions are obtained wherein the polyester-amide component is a copolymer of one or more organic dicarboxylic acids with 2,2-bis(4-hydroxyphenyl)hexafluoropropane and an aminoalkyl-terminated organopolysiloxane.
