  • Patent number: 7901748
    Abstract: An ink jet recording element with a support having thereon an image-receiving layer of inorganic particles and stabilizer particles, the stabilizer particles being free of any organic solvent and containing greater than about 80% by weight of a water-insoluble antioxidant and having a mean particle size of greater than 5 nm, the inorganic particles being greater than about 50% by weight of the ink receiving layer.
    Type: Grant
    Filed: December 12, 2001
    Date of Patent: March 8, 2011
    Assignee: Eastman Kodak Company
    Inventors: Yongcai Wang, Kurt M. Schroeder, Lori J. Shaw-Klein, Thomas P. Nicholas, Sridhar Sadasivan, Christine M. Vargas
  • Patent number: 7829160
    Abstract: An inkjet recording element comprising an absorbent support, a porous base layer nearest the support and comprising precipitated calcium carbonate, a porous ink-receiving intermediate layer above the base layer and comprising hydrated alumina, and a porous ink-receiving upper layer above the intermediate layer and comprising a mixture of hydrated and fumed alumina. Also disclosed is an advantageous method of making such inkjet recording materials.
    Type: Grant

  • Patent number: 7718237
    Abstract: An inkjet recording element comprising an absorbent support, a porous base layer nearest the support, a porous ink-receiving intermediate layer above the base layer, and a porous ink-receiving upper layer above the intermediate layer. The base layer and intermediate layers are each present in an amount of at least 25 g/m2 and the total dry weight coverage of the base layer, the intermediate layer, and the upper layer is 60 to 130 g/m2 in order to handle high fluxes of ink compositions during printing and to provide high gloss upon calendering. Also disclosed is an advantageous method of making such inkjet recording materials.
