摘要:
A method of fusing an electrostatographic toner image to provide desirable levels of gloss in the fused image is disclosed. The toner particles have a loss tangent value of 1.2 or more upon fusing with combined heat and pressure. The unfused toner image 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 image is cooled and a release zone where the image is released from the fusing member at a temperature where no toner image offset occurs.
摘要:
A method of fusing an electrostatographic toner pattern to provide different levels of gloss in the pattern is disclosed. The pattern comprises at least one toner image formed from toner particles having a loss tangent value of 1.2 or less and at least one other toner image formed from toner particles having a loss tangent value of 1.6 or more. The pattern 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 pattern is cooled and a release zone where the pattern is released from the fusing member at a temperature where no toner image offset occurs.
摘要:
Coated fuser members such as a fuser roller, pressure roller, or fuser belt, and the method of making the coated fuser members are disclosed. The release coating comprises an outermost layer of fluoropolymer resin uniquely bonded to a fluoroelastomer layer by means of a fluoropolymer-containing polyamide-imide primer layer.

The present invention relates to imaged photographic elements comprising an overcoat layer of a water-dispersible, hydrophobic polyester resin having the following general formula: In—P—Am wherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an Asiatic group comprising a straight or branched chain fatty acid or triglyceride thereof having from about 6 to about 24 carbon atoms; and m is an integer from 3-8. Such a protective overcoat provides excellent stain resistance for an imaged photographic element.

The present invention relates to the use of quaternary ammonium salt as a charge-control agent for electrostatic toner contained in a dry developer composition. The dry, particulate, electrostatic toner composition of the present invention comprises(a) a polymeric binder and(b) a charge-control agent comprising an N-benzyl quaternary ammonium salt, wherein the benzyl ring contains at least one substituent with a Hammett substituent constant that is greater than zero.
摘要:
An ink jet printing process for improving the durability and image quality of an ink jet image having the steps of a) providing an ink jet recording element having a support having thereon an image-receiving layer containing an ink jet image; and b) applying over the surface of the image-receiving layer an overcoat layer of water-dispersible, smectite clay particles.
