Patent number: 7833590Abstract: The present invention is drawn to compositions and coated substrates wherein a hydrophobic backside coating layer can be implemented for use that mitigates ink transfer, surface damage, smudging, and sticking between stacked sheets in output trays of ink-jet ink printers. The backside coating can comprise hydrophobic beads suspended in a polymeric blend having a hydrophilic polymeric binder component and a hydrophobic polymeric binder component. Alternatively, the coating can comprise a hydrophobic binder blended with a natural wax. Either coating can be applied directly to the backside of a media substrate or on top of an existing hydrophilic layer that is typically applied for curl and sheet feed performance.Type: GrantFiled: October 19, 2004Date of Patent: November 16, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Bor-Jiunn Niu, Stefan Schüttel, Meinrad Schaer

Patent number: 7112629Abstract: Ink-receiving print media products capable of producing high quality printed images which are light-fast, humid-fast, have low coalescence (graininess) levels, and are characterized by other beneficial attributes. The print media products have at least one ink-receiving layer supported by a substrate. The ink-receiving layer includes a binder blend designed to achieve the aforementioned goals, namely, gelatin, a poly(vinyl alcohol-polyethylene oxide) copolymer, and a poly((styrene)-(n-butyl acrylate)-(methyl methacrylate)-(2-(tert-butylamino) ethyl methacrylate)) copolymer. One or more optional pigments and/or additional binders can also be included within the ink-receiving layer. The ink-receiving layer may optionally be employed in combination with one or more additional material layers thereover or thereunder which can contain, for example, one or more pigments and/or binders.Type: GrantFiled: December 7, 2004Date of Patent: September 26, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Bor-Jiunn Niu, Stefan Schuttel, Meinrad Schaer

Publication number: 20050196561Abstract: There is described a recording medium and related ink jet printing method which comprises the steps of: 1) printing onto a receiving medium which comprises a substrate coated with at least one ink receiving layer comprising polymeric particles having film forming temperatures between 60° to 140° C. and a binder, and 2) heating the printed image to form a stable image-protecting coating. Preferably the printed image is heated by passing through a laminator. Alternatively the printed image is heated by passing through a laminator in conjunction with a second, inert releasing sheet which is held against the top surface of the print material. The second sheet may be used to produce a particular appearance to the final image such as high gloss or a security pattern. The receiving layers of the invention provide bright images after printing and fusing which show a high level of scratch and rub resistance even when wet.Type: ApplicationFiled: May 3, 2005Publication date: September 8, 2005Inventors: Jeffrey King, Karen Taylor, Simon Leggett, Stefan Schuttel, Roger Brentnall
