The polymeric multi-layer reflector has numerous alternating layers of at least two different polymeric materials and reflects at least 50% of actinic radiation in the range of wavelengths to which the phosphor is sensitive. The use of this polymeric multi-layer reflector in the radiographic phosphor panel provides increased photographic speed when it is used in imaging assemblies with photosensitive recording materials such as radiographic silver halide films.Type: GrantFiled: June 18, 2001Date of Patent: February 18, 2003Assignee: Eastman Kodak CompanyInventors: Peter T. Aylward, David J. Steklenski, James F. Elman

Patent number: 6440541Abstract: Described is a metallized article, and a method for making the same, comprising a substrate having a polyurethane basecoat disposed thereon and with a layer of electrically discrete metallic islands of a corrosion prone metal disposed on the basecoat. A cross-linked polyurethane top coat, which is bound to an organosilane, preferably an epoxy silane, is disposed on and encapsulates the discrete metallic islands. The organsilane is also bound to the metallic islands.Type: GrantFiled: April 3, 2000Date of Patent: August 27, 2002Assignee: Textron Automotive Company Inc.Inventors: William M. Humphrey, Adam Murano

Patent number: 6395348Abstract: Pressure sensitive adhesive tapes are manufactured by continuously extruding polypropylene to form a web which is cooled and set and slit at transversely spaced positions into a plurality of side by side continuous tapes. After slitting each tape is drawn longitudinally and heat set to effect monoaxial orientation of the tape. A release coating to the first tape surface and a coating of a pressure sensitive adhesive to the second tape surface. Each continuous tape with the release coating and the adhesive coating thereon is wound into a series of cylindrical tape spools each containing a length of the tape.Type: GrantFiled: December 22, 2000Date of Patent: May 28, 2002Assignee: KT Holdings Inc.Inventor: Lawrence O'Connor

Patent number: 6368677Abstract: A method for providing a waterborne, inorganic barrier coating to a polyolefin substrate is described. The method involves applying a primer composition containing a vinyl polymer, wherein at least 75% of the polymer repeat units contain side groups having hydroxyl moieties, to the substrate. This primer coating facilitates the application and binding of the subsequently applied barrier coating composition to the substrate.Type: GrantFiled: May 15, 2001Date of Patent: April 9, 2002Assignee: Hoechst Trespaphan GmbHInventors: Michael A. Hubbard, James A. McCaulley, Douglas R. Holcomb
