  • Ink acceptor material containing a phospholipid
    Patent number: 5733672
    Abstract: An acceptor material for printing by ink-jet primers forms water-resistant, light-stable ink records with aqueous ink jet inks. The material comprises a support such as polyester film and a coating containing a water-soluble phospholipid mordant that forms insoluble compounds with and immobilizes the dyestuffs of the ink jet inks and a water managing polymer, preferably, hardened gelatin, which quickly renders the material dry-to-the-touch after contact with the aqueous ink.
    Type: Grant
    Filed: June 5, 1996

    Assignee: Labelon Corporation

  • Ink acceptor material containing an amino compound
    Patent number: 5656378
    Abstract: An acceptor material for printing by ink-jet printers forms water-resistant, light-stable ink records with aqueous ink jet inks. The material comprises a support such as polyester film and a coating containing a water-soluble high molecular weight amino compound that forms insoluble compounds with and immobilizes the dyestuffs of the ink jet inks and a water managing polymer, preferably, hardened gelatin, which quickly renders the material dry-to-the-touch after contact with the aqueous ink.
