  • Optically variable interference pigments
    Patent number: 6706109
    Abstract: Optically variable interference pigments are composed of platelets of at least partly core-free titanium dioxide-coated substrate of about 1-25 mm particle size and an interference thickness of about 5-600 nm which have an oxide coating thereon.

  • Rutile titanium dioxide effect pigments and production thereof
    Patent number: 6626989
    Abstract: A pearlescent pigment comprising substrate particles having an adherent layer of rutile titanium dioxide thereon is prepared by effecting the deposition of hydrous titanium dioxide on the substrate particles after contacting the particles at elevated pH with titanium tetrachloride.

  • Interference pigments
    Patent number: 6485556
    Abstract: Pearlescent pigment having a chromium coating thereon and an iron oxide coating on the chromium coating are intensely colored, almost phosphorescently colored, and are highly reflective.
    Type: Grant
    Filed: October 10, 2001

    Assignee: Engelhard Corporation
    Inventor: Carmine V. DeLuca, Jr.
  • Rutile titanium dioxide coated micaceous pigments formed without tin
    Patent number: 5433779
    Abstract: A pearlescent pigment comprising micaceous particles having an adherent layer of rutile titanium dioxide thereon is prepared by effecting the deposition of hydrous titanium dioxide on the micaceous particles in the presence of iron and calcium, magnesium and/or zinc ions without the use of tin.
    Type: Grant
    Filed: November 7, 1994
    Date of Patent: July 18, 1995

    Inventor: Carmine V. DeLuca, Jr.
  • Process for stabilizing metal oxide-coated mica pigments against light and moisture
    Patent number: 5156889
    Abstract: Metal oxide coated mica pigments are provided with enhanced light and moisture stability by providing on the particle surfaces of coating of hydrous aluminum oxide.
    Type: Grant
    Filed: December 11, 1991
    Date of Patent: October 20, 1992
    Assignee: The Mearl Corporation
    Inventor: Carmine V. DeLuca, Jr.
  • Light and moisture resistant metal oxide-coated mica pigments
    Patent number: 5091011
    Abstract: Metal oxide coated mica pigments are provided with enhanced light and moisture stability by providing on the particle surfaces a coating of hydrous aluminum oxide.
    Type: Grant
    Filed: March 12, 1990
    Date of Patent: February 25, 1992
    Assignee: The Mearl Corporation
    Inventor: Carmine V. DeLuca, Jr.
  • Rutile-coated mica nacreous pigments and process for the preparation thereof
    Patent number: 4038099
    Abstract: Nacreous pigment products comprising mica particles coated with translucent layers consisting essentially of titanium dioxide in the rutile form. A process for the preparation of such pigment products is disclosed, involving treatment with tin compounds, so that the TiO.sub.2 coating will crystallize mainly in the rutile form rather than as anatase during calcination of the pigment. The rutile-coated mica exhibits markedly enhanced light stability as compared with anatase-coated mica pigment products.
