Patent number: 6197383Abstract: The present invention features coating compositions and methods for improving the quality of images printed on a paper substrate. The novel coating compositions contain a coating agent comprising a mixture of a polyacid and a polybase. When applied to a sized paper substrate, the coating compositions provide a coated paper substrate that provides high quality printed images when printed with an ink containing a reactive dye having ionizable and/or nucleophilic groups capable of reacting with the coating agent. Images printed on a paper substrate coated with the coating composition of the invention are bleed-resistant, water-resistant (e.g., water-fast), and/or are characterized by an enhanced chroma and hue.Type: GrantFiled: March 31, 1999Date of Patent: March 6, 2001Assignee: SRI InternationalInventor: Asutosh Nigam

Patent number: 5843743Abstract: Water soluble macromers are modified by addition of free radical polymerizable groups, such as those containing a carbon-carbon double or triple bond, which can be polymerized under mild conditions to encapsulate tissues, cells, or biologically active materials. The polymeric materials are particularly useful as tissue adhesives, coatings for tissue lumens including blood vessels, coatings for cells such as islets of Langerhans, coatings, plugs, supports or substrates for contact with biological materials such as the body, and as drug delivery devices for biologically active molecules.Type: GrantFiled: June 6, 1995Date of Patent: December 1, 1998Assignee: Board of Regents, The university of Texas SystemInventors: Jeffrey A. Hubbell, Chandrashekhar P. Pathak, Amarpreet S. Sawhney, Neil P. Desai, Jennifer L. Hill, Syed F. A. Hossainy

Patent number: 5571557Abstract: A transfer sheet for applying images to glass, plexiglass and the like to simulate the look of an etched surface is prepared by a three-step screen printing process wherein a polystyrene or release coated paper base is first coated with nitrocellulose and then heated. Thereafter a further coat comprising a combination of nitrocellulose, a silica flattening agent and mica/silica is applied followed by further heating. A screen printable solvent based adhesive suitable for polystyrene or paper is then applied, then heated and, thereafter a slip sheet applied to the adhesive side to permit stacking.Type: GrantFiled: May 9, 1995Date of Patent: November 5, 1996Assignee: Chartpak, Inc.Inventors: Norman P.

Patent number: 5053212Abstract: Novel compositions are provided for the production of hydroxyapatite, where a dry mixture is provided which combines a calcium source and an acidic phosphate source, particularly monocalcium phosphate monohydrate or orthophosphoric acid crystals. These two are combined, optionally with other ingredients, with mechanical mixing, resulting in partial reaction or intimate combination to produce a product which requires less water for formation of a desired viscosity, has enhanced mechanical properties and is physilogically acceptable.Type: GrantFiled: July 27, 1990Date of Patent: October 1, 1991Assignee: Norian CorporationInventors: Brent R. Constantz, Bryan Barr, Kevin McVicker
