  • Publication number: 20050238827
    Abstract: Disclosed is an ink-jet recording sheet which has excellent glossiness and ink absorbability, improved storage stability of images, such as light fastness and water resistance, and satisfactory coating strength. An ink-jet recording sheet, in which the specular gloss at an angle of 60 degrees according to JIS Z8741 is 50% or more, includes an ink-absorbing layer disposed on a substrate, and a gloss-developing layer disposed on the ink-absorbing layer, the gloss-developing layer being formed by applying a coating compound containing a water-soluble zirconium salt onto the ink-absorbing layer, followed by drying. The content of the water-soluble zirconium salt, in terms of ZrO2, is 10% by weight or more of the total solids in the coating compound, and the coating compound optionally contains a binder resin in an amount not exceeding the zirconium salt content in terms of ZrO2.

  • Patent number: 6362131
    Abstract: A receiver paper used in combination with a thermally transferrable sheet, such as an ink ribbon, in which a laminated layer of the thermally transferrable sheet can be positively transferred, with the receiver paper exhibiting superior running performance and resistance to blocking to enable a picture of high quality and high resolution to be produced. To this end, there is provided a receiver paper made up of substrate and a dye reception layer formed on the substrate. The dye reception layer contains a copolymer of a compound having a pre-set chemical formula and another monomer.
