Patent number: 6902807Abstract: Diffractive pigment flakes are selectively aligned to form an image. In one embodiment, flakes having a magnetic layer are shaped to facilitate alignment in a magnetic field. In another embodiment, the flakes include a magnetically discontinuous layer. In a particular embodiment, deposition of nickel on a diffraction grating pattern produces magnetic needles along the grating pattern that allow magnetic alignment of the resulting diffractive pigment flakes. Color scans of test samples of magnetically aligned flakes show high differentiation between illumination parallel and perpendicular to the direction of alignment of the magnetic diffractive pigment flakes.Type: GrantFiled: September 13, 2002Date of Patent: June 7, 2005Assignee: Flex Products, Inc.Inventors: Alberto Argoitia, Vladimir P.

Patent number: 6881249Abstract: The present invention provides microparticles that create permanent tissue markings, such as tattoos, designed in advance for change and/or removal on demand, as well as methods for implanting the microparticles in tissue and changing and/or removing the resulting markings. Colored microparticles are constructed with specific electromagnetic absorption and/or structural properties that facilitate changing and/or removing tissue markings made using the microparticles by applying specific energy (such as electromagnetic radiation from a laser or flash-lamp) to the tissue marking site.Type: GrantFiled: March 14, 2003Date of Patent: April 19, 2005Assignees: The General Hospital Corporation, Freedom-2, LLCInventors: Richard R. Anderson, Susanna K. Mlynarczyk, Craig A. Drill

Patent number: 6878197Abstract: A color set for forming an ink jet image comprising: at least two color inks, each ink comprising a carrier and a pigment; wherein the Relative Gloss Variability (RGV) (Equation A) among inks is less than 10%; when 60° is used as the specular angle. RGV ? ( % ) = ? I = 1 N ? ? ( Gloss ? ( Imaged ? ? ? Area ) I - AG ) ? AG N Where AG = ? I = 1 N ? Gloss ? ( Imaged ? ? ? Area ) I N Equation ? ? ? ( A ) I is a variable which identifies a certain color patch used in the evaluation, N is the total number of color patches used in the evaluation.Type: GrantFiled: December 28, 2001Date of Patent: April 12, 2005Assignee: Eastman Kodak CompanyInventors: Huijuan D.
