Abstract

An inkjet recording method characterized by adhering a receiving solution (A) to at least areas on a recording medium (R) which are to be printed with an inkjet ink (I) or the whole surface of the medium (R) which is to be printed, said receiving solution (A) being a solution obtained by dissolving (inclusive of dispersing) one or more metal salts (S) selected from among at least divalent, calcium salts, magnesium salts, nickel salts, aluminum salts, boron salts, and zinc salts and one or more resins (B) having hydrophilic groups in an aqueous solvent in such amounts that the concentrations of the metal salts (S) and the resins (B) fall within the range of 0.005 to 2.0 mol/l and within the range of 0.5 to 20 mass % respectively, and then applying the inkjet ink (1) to areas where the metal salts are present in an adhered state to carry out printing. Said inkjet ink (I) is an ink which has a pigment (P), an anionic resin emulsion (E), and an aqueous solvent, and in which phosphorus-containing groups each having at least one P—O or P═O bond are bonded to the surface of the pigment (P) or the surface of the anionic resin emulsion (E).
