  • Aluminum substrates and lithographic printing plate precursors
    Patent number: 8632940
    Abstract: Electrochemically grained and anodized aluminum supports are treated with a post-treatment coating solution containing a polymer derived at least in part from vinyl phosphonic acid and phosphoric acid. This post-treated support is useful as substrates in the preparation of lithographic printing plate precursors. The post-treatment substrate treatment enables wide latitude in manufacturing and compatibility with silicate-free developers to achieve negligible background staining and oxide attack.
    Type: Grant
    Filed: April 19, 2011
    Date of Patent: January 21, 2014
    Assignee: Eastman Kodak Company
    Inventors: Gerhard Hauck, Celin Savariar-Hauck, Oliver R. Blum, Michael Nielinger

  • Aluminum lithographic substrate and method of making
    Publication number: 20080003411
    Abstract: Aluminum-containing metal sheets can be electrochemically grained to provide a center line average roughness (Ra) of less than 0.60 ?m and an average maximum pit depth (Rv) of less than 4.5 ?m using a current density of at least 50 A/dm2 and a charge density less than or equal to 850 coulombs/dm2. This improved metal sheet can be used as substrates for imageable elements including lithographic printing plates that exhibit reduced blanket toning.
