  • Publication number: 20140055520
    Abstract: An inkjet recording method which suppresses feathering and color bleeding and is excellent in fixability to a recording medium. The inkjet recording method includes the steps of applying an ink-receiving solution prepared by dissolving in an aqueous solvent at least one metal salt having a water solubility of 0.1 mol/l or more, selected from calcium salts, magnesium salts, nickel salts and zinc salts having a valence of 2 or more, to at least the surface to be printed by using an inkjet ink or the entire surface of a recording medium; and printing on the metal salt adhered part by using the inkjet ink comprising at least a pigment, a resin emulsion and an aqueous solvent containing a surfactant. Further, a phosphorus-containing group having at least one P—O or P?O bond is bound to the surface of the pigment.

    Abstract: A hardcoat for a plastic substrate film is provided which has good suitability for printing and satisfactory hardness, can prevent influence of the deformation of a plastic substrate film from extending to the hardcoat, and is resistant to cracking and peeling. The hardcoat is produced from a coating component containing one or more organic components having a polymerizable functional group and an inorganic filler, at least one of the organic components being free from a hydrogen bond-forming group. In the hard coat, the content of the inorganic filler in the surface of the hardcoat is higher than that in the interior of the hardcoat. The hardcoat can be applied to antireflection films and hologram labels.
