Patents by Inventor DAVID DE LA FUENTE

DAVID DE LA FUENTE has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Colorant including a mixture of pigments
    Patent number: 10189997
    Abstract: A colorant including a mixture of pigments is disclosed. The pigments have a similar coloration but different resistance to corrosion. The mixing ratio is selected to optimize the corrosion resistance against color brightness, and/or acidic corrosion resistance against alkali corrosion resistance of the colorant.
    Type: Grant
    Filed: October 23, 2017
    Date of Patent: January 29, 2019
    Assignee: VIAVI Solutions Inc.
    Inventors: Cornelis Jan Delst, Vladimir P. Raksha, David de la Fuente
  • Durable optical interference pigment with a bimetal core
    Patent number: 10031269
    Abstract: In a plurality of asymmetric color-shifting flakes, each flake has an asymmetric magnetic core with a magnetic layer visible on the first side of the core and a non-magnetic reflector layer on the magnetic layer, visible on the second side of the core. The flake has a spacer layer and an absorber layer on the first side of the core, and also a spacer layer and an absorber layer on the second side of the core, for providing color shifting effects. The material of the magnetic layer is different from the material of the reflector layer, and may be more stable when exposed to a chemical. When a coating with the asymmetric color-shifting flakes is exposed to the chemical, it may have better optical performance than a coating with symmetric color-shifting flakes.
