  • Patent number: 8080291
    Abstract: An ink jet recording medium having a gas-permeable substrate, and an ink receiving layer and a surface layer provided in that order on the gas-permeable substrate, wherein the surface layer is formed through the steps of (1) applying a coating liquid comprising a first inorganic pigment and a binder onto the ink receiving layer, and (2) applying a coagulating liquid comprising a coagulant and a second inorganic pigment having a refractive index higher by 0.30 or more than that of the above first inorganic pigment and an average particle size of 100 nm or less onto the applied coating liquid to subject the coating liquid to a coagulating treatment followed by pressing a coating layer including the coating liquid and the coagulating liquid against a heated casting drum while the coating layer is in a wet condition to subject the coating layer to a cast treatment.
