Patent number: 7713617Abstract: A charge control composition for controlling the resistivity of recording media used in electrophotographic printing processes is herein disclosed. The charge control composition is included in one or more layers applied to a substrate of the recording media. The charge control composition is an admixture of an electrolyte, a solvent, an organic carrier, and a co-organic carrier. The organic carrier is selected to form and maintain at least some physical and/or chemical bonds with the solvent such that he organic carrier will retain a fraction of the solvent during a high temperature fusion procedure.

Patent number: 6869647Abstract: Ink-receiving print media products having multiple capabilities including (A) minimal drying time; (B) improved smear-fastness; (C) a high level of water-fastness; (D) the ability to generate high-definition images; and (E) excellent ink compatibility. The media products have at least one ink-receiving layer on a substrate (e.g. paper pre-coated with one or more binders and/or pigments). The ink-receiving layer includes a pigment (boehmite, pseudo-boehmite, or mixtures thereof) optimally combined with a special binder blend [polyvinyl alcohol, a poly(vinyl acetate-ethylene) copolymer, and a poly(vinyl pyrrolidone-vinyl acetate) copolymer]. Also included is a special dye fixative (namely, a cationic emulsion polymer) which provides enhanced water-fastness. This fixative is of a particular type (a quaternary amine) that also allows high pigment levels to be employed (at least about 65% by weight) which further promotes the foregoing benefits.Type: GrantFiled: August 30, 2001Date of Patent: March 22, 2005Assignee: Hewlett-Packard Development Company L.P.Inventors: Loretta Ann Grezzo Page, Richard J.

Patent number: 6869650Abstract: The present invention is drawn to the thermal transfer overcoating of images printed on porous media, and methods of overcoating images printed on porous media. Upon use of the systems and methods of the present invention, a thermally coated print is generated that can comprise a porous media substrate having printed thereon a digitally produced image. The digitally produced image and the porous media substrate is thermally coated by an adhesive protective layer, wherein the adhesive protective layer has a tangent d that is greater than 1 and melt viscosity less than 1×105 Pa.·sec. as applied above its phase transition temperature. Thus, the voids in the porous media substrate can be substantially filled, and further, substantially no tags remain on the print.Type: GrantFiled: June 11, 2002Date of Patent: March 22, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Eric L Burch, Vladek P Kasperchik, Shilin Guo, David J Arcaro, Gary E Hanson, Maximo Gayoso, Richard J McManus, Dan M Weeks

Patent number: 6454388Abstract: A technique for handling residual ink that is from time to time present on the orifice plate of an ink-jet print cartridge. In one preferred embodiment, an ink-jet print cartridge is equipped with an ink-receptive member, such as an absorbent pad. The pad is located so that a service station wiper will move the residual ink from the orifice plate and spread it across the pad. The pad absorbs the ink. In essence, the ink is sequestered on the cartridge, in the pad. The exterior surface of the pad dries quickly so that there is little likelihood of developing a tacky area over the pad to which fibers may stick and degrade print quality.Type: GrantFiled: December 29, 1999Date of Patent: September 24, 2002Assignee: Hewlett-Packard CompanyInventors: Frank J.
