Patent ID: 8163360

Claim:
An inkjet recording medium comprising an ink-receiving layer, the ink-receiving layer being formed by applying a pigment dispersion to a substrate, wherein the pigment dispersion contains an inorganic pigment dispersed therein, a binder, and a metal compound that adheres to the inorganic pigment, such that the concentration of a metal ion of the metal compound that is dissolved in the pigment dispersion does not exceed 0.05 mol/L, and wherein the inorganic pigment to which the metal compound is adhered is obtained by at least one process selected from the group consisting of manufacturing processes (1) to (3): (1) a manufacturing process having a hydrothermal synthesis treatment of inorganic pigment performed in the presence of the metal compound under the conditions of a temperature of from 100° C. or more to less than 350° C.; (2) a manufacturing process having a step of mixing a slurry of a dispersion of inorganic pigment and the metal compound with a stirrer and a step of drying the mixed slurry by a spray-dry method at 100 to 300° C.; and (3) a manufacturing process having a step of adding a metal compound solution to an inorganic pigment dispersion and stirring and a step of adding an alkali dispersion to neutralize.
