Publication number: 20140154520Abstract: A process for preparing embossed fine particulate thin metal flakes having high levels of brightness and color intensity. The process comprises forming a release coat on a flexible polymeric carrier film, embossing the release coat with a diffraction grating pattern that is monoruled at an angle above 45°, vacuum metalizing the embossed release surface with a highly reflective metal such as aluminum, and solubilizing the metalized release coat in a solvent for removing the metal from the carrier to form embossed metal flakes that replicate the embossment pattern. The flakes are recovered from the solution containing the solvent and release coat polymer while avoiding high shear, particle sizing or other application of energy that would excessively break up the flakes, so that the D50 particle size of the flakes is maintained at or above 75 microns.Type: ApplicationFiled: January 3, 2014Publication date: June 5, 2014Applicant: Eckart America CorporationInventor: James P.

Publication number: 20110031640Abstract: A process for making functional or decorative flakes or platelets economically and at high production rates comprises applying a multi-layer sandwich of vapor deposited metal and release coats in alternating layers to a rotating chilled drum or suitable carrier medium contained in a vapor deposition chamber. The alternating metallized layers are applied by vapor deposition and the intervening release layers are preferably solvent soluble thermoplastic polymeric materials applied by vapor deposition sources contained in the vapor deposition chamber. The multi-layer sandwich built up in the vacuum chamber is removed from the drum or carrier and treated with a suitable organic solvent to dissolve the release coating from the metal in a stripping process that leaves the metal flakes essentially release coat free.Type: ApplicationFiled: October 25, 2010Publication date: February 10, 2011Applicant: AVERY DENNISON CORPORATIONInventors: Karl JOSEPHY, James P.

Publication number: 20030178734Abstract: A multi-layer sandwich of vapor deposited metal and release coats in alternating layers is applied to a drum or carrier in a vapor deposition chamber. The metallized layers are applied by vapor deposition. The release layers are solvent soluble thermoplastic or lightly crosslinked polymeric materials applied by vapor deposition in the chamber. The multi-layer sandwich is removed and treated with solvent to dissolve the release coating from the metal flakes. The release coat material can be a radiation curable, crosslinkable vapor deposited polymeric material of low crosslink density. A high energy radiation source crosslinks the release material to produce tack-free, solvent soluble release coat layers. The multi-layer vapor deposit can be built up on an endless belt passing from the chamber through a separate vacuum lock. Both chambers are at vacuum pressures below atmospheric while depositing the flake material.Type: ApplicationFiled: November 27, 2002Publication date: September 25, 2003Inventors: Karl Josephy, James P.

Patent number: 6068691Abstract: Finely divided embossed metal particles are prepared by forming an embossment on a carrier surface in which the embossment comprises a machine readable image produced by a diffraction grating pattern, a holographic image pattern or an image visible solely by optical magnification. A layer of metal is applied to the surface so the layer adopts the complement or the embossment. The layer is then separated from the surface and reduced to embossed particles. Alternatively, the embossment can be formed on the carrier sheet directly or on the outer surface of a release coating formed on the carrier sheet. When removing the film of metal from the release-coated carrier, the carrier sheet with the release coating and film of metal can be passed through a release environment which causes the release coating to separate the film and carrier, but which is nondestructive of the metal.Type: GrantFiled: September 29, 1997Date of Patent: May 30, 2000Assignee: Avery Dennison CorporationInventors: Richard G.

Patent number: 5650248Abstract: A method of identifying an object by a machine readable image applied to it in which the image is produced by a plurality of fine particles embossed with a machine readable pattern produced by replicating contact with a diffraction grating having from about 5,000 to about 11,000 grooves per cm.Type: GrantFiled: June 7, 1995Date of Patent: July 22, 1997Assignee: Avery Dennison CorporationInventors: Richard G.

Patent number: 5624076Abstract: Embossed, finely-divided, thin, bright-metal particles are prepared by forming an embossed release surface on at least one side of a carrier sheet in which the embossed pattern comprises a diffraction grating having from about 5,000 to 11,000 grooves per cm. A metal film is deposited on the release surface so that the metal film conforms to the embossed surface. The carrier sheet is passed with the release surface and the metal film through a release environment which causes the release surface to separate from the metal film. The metal film is removed from the release surface in a particulate form to produce metal particles substantially free of the release surface. The particles are collected in a solvent which is non-reactive with the metal. The metal particles are then broken into pigment particles having an average diameter between about 10 to about 50 microns. The film may also take the form of an optical stack.Type: GrantFiled: June 7, 1995Date of Patent: April 29, 1997Assignee: Avery Dennison CorporationInventors: Richard G. Miekka, Dennis R.

Patent number: 5424517Abstract: A food package including a package body forming a food receiving cavity for storing and heating a food item in a microwave oven. Specifically, the package body includes a bottom panel and a top panel with side panels joining the bottom and top panel. An impedance matching element is provided on at least one of the panels for impedance matching microwave energy entering the package. The impedance matching element is preferably a contiguous film of thinly flaked material embedded in a dielectric binder which is sized and shaped with respect to the food to cause impedance matching to elevate the temperature of the food in predetermined areas dependent upon the size and spacing of the film without interacting with the microwave energy to produce heat. The film may also be shaped in the form of a convex lens to direct impedance matched microwave energy toward the food to elevate the temperature of the food in a predetermined area.Type: GrantFiled: October 27, 1993Date of Patent: June 13, 1995Assignee: James River Paper Company, Inc.Inventors: Charles C. Habeger, Jr., Kenneth A. Pollart, Karl Josephy, James P. Rettker, Richard M. Thomas

Patent number: 5407234Abstract: An index divider is reinforced using a polyester film having a bonding coating on one side thereof for bonding the polyester film to the index divider, and a toner-receptive polymer coating on the other side thereof. The toner-receptive coating may be N-Butyl Methacrylate polymer. Other polymers may be used, which have microscopic penetration points to bond with xerographic toner, and which maintain their integrity at the high temperatures and pressures used to bond the polyester film to the index dividers.Type: GrantFiled: December 11, 1992Date of Patent: April 18, 1995Assignee: Avery Dennison CorporationInventors: James P.
