Patent number: 7086732Abstract: A fusible print medium having a photobase layer, a vehicle sink layer, and a colorant-receiving layer. The colorant-receiving layer includes core-shell polymer particles that have a hydrophilic shell and a fusible hydrophobic core. Upon exposure to a sufficient heat, the colorant-receiving layer inverts from a porous, hydrophilic surface into a continuous layer that encapsulates colorant in hydrophilic domains. A method of forming the fusible print medium and producing a photographic quality image is also disclosed.Type: GrantFiled: July 28, 2003Date of Patent: August 8, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Vladek P.

Patent number: 6833169Abstract: A media sheet which can be used with a new system and method of the present invention is provided. Specifically, a media sheet can comprise a substrate, a porous dye-receiving layer deposited on the substrate, and a porous ionic layer deposited on the porous dye-receiving layer. Thus, when the ink-jet ink is printed onto the media sheet, ink-jet ink passes substantially through the porous ionic layer and onto the porous dye-receiving layer forming an ink-jet ink-containing media sheet. A fluid sealant composition having an opposite polarity than the ionically-charged surfaces can then be applied. Upon application of the fluid sealant to the ink-jet ink-containing media sheet, an interpolymer complex is formed sealing the ink-jet ink in the media sheet.Type: GrantFiled: October 8, 2002Date of Patent: December 21, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Vladek P Kasperchik, Gary Allan Ungefug
