Patent number: 7705070Abstract: The present invention is directed to latex particulates having a greater concentration of acid at their surfaces than at their cores. A method of making such particulates can comprise copolymerizing an acidic monomer with a non-acidic monomer so as to yield a copolymer chain having more acidic monomer at one end than at the other.Type: GrantFiled: July 14, 2006Date of Patent: April 27, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Kent D. Vincent, Sivapackia Ganapathiappan

Patent number: 7705069Abstract: An ink jet ink composition comprised an anti-curl agent and ink jet printing processing using such ink jet ink composition. The ink jet ink composition includes a hyperbranched polymer. The hyperbranched polymer acts as an anti-curl agent to control curl during a printing process. The anti-curl agent, i.e., the hyperbranched polymer, may be present in the ink amounts less than conventional anti-curl agents and still effectively control curl without detrimentally effecting intercolor bleed control water fastness or drying. Additionally, the ink composition do not exhibit increases in viscosity, and problems associated therewith, that occur in ink composition using conventional anti-curl agents.Type: GrantFiled: November 22, 2004Date of Patent: April 27, 2010Assignee: Xerox CorporationInventors: Erin M. Reinhardt, Daniel A. Foucher

Patent number: 7696263Abstract: The present invention relates to a stimulus responsive composition, which includes a polymer complex that a polymer including repeated units of polyvinyl ether structure is chemically bonded to a functional substance, and a solvent. It is desirable that a solvent is water and that the polymer in the composition contains a polyvinyl ether structure. The present invention also relates to an ink composition including the above composition, an image forming method and image forming device using the above composition, and recording medium contains a stimulating material or composition which stimulates the above composition.Type: GrantFiled: November 29, 2005Date of Patent: April 13, 2010Assignee: Canon Kabushiki KaishaInventors: Koichi Sato, Ikuo Nakazawa, Sakae Suda, Masayuki Ikegami

Patent number: 7691920Abstract: An ink jet ink includes an ink vehicle, wherein the ink vehicle includes at least one wax monomer functionalized to include in the chain at least one reactive group curable upon exposure to radiation. The reactive group is preferably curable via cationic or free radical polymerization. In a preferred embodiment, the ink vehicle includes a wax monomer having a structure: wherein C represents a cationically curable group and R represents a radically curable group. The inks may be used to form an image by jetting the ink onto a transfuse member surface, increasing the viscosity of the ink upon the transfuse member surface, subsequently transferring the ink from the transfuse member surface to an image receiving substrate, and exposing the ink to radiation following the transfer to the image receiving substrate to effect reaction of the at least one reactive group.Type: GrantFiled: January 14, 2005Date of Patent: April 6, 2010Assignee: Xerox CorporationInventors: Jennifer L. Belelie, Peter G. Odell, Eniko Toma, Paul F. Smith, Rina Carlini
