    Abstract: A recording medium for ink, capable of rapidly absorbing large amounts of ink, showing excellent color forming ability and capable of suppressing image deterioration caused by dye displacement that occurs when an image is stored in humid conditions and image deterioration caused by light when a printed image is displayed, and providing a printed image showing excellent long-term stability. The invention also provides a recording medium for ink having at least one layer provided on a substrate, and an ink receiving layer containing alumina hydrate as an outermost layer. A surface of the substrate at least on the side of the ink receiving layer is subjected to a cationizing treatment. An undercoat layer is provided on the same side as the cationizing treatment, to obtain cations in a predetermined distribution. The outermost ink receiving layer is provided on the undercoat layer.

  • Patent number: 7172651
    Abstract: Pigment suitable for use in coating compositions for inkjet recording media. Surfaces of an inorganic particulate are interacted with a water-soluble polyvalent metal salt in an aqueous medium. The treated particle surfaces have a significant cationic surface charge imparted to them. The salt is a salt of a metal of Group II or Group III of the Periodic Table. Inkjet recording media treated with a coating composition containing the above pigment provide high density, fast-drying, and non-feathering ink images with suitable water fastness, while the coating compositions also offer cost advantages and improved rheology at higher pigment levels over coatings based on silica pigments.
