    摘要： A main object of the present invention is to provide an ink composition which has superior storage stability, is resistant to bleeding, and has good fixability to paper, enables printing of a clear image. In the present invention, the above objecct can be attained by providing an ink composition comprising a pigment dispersion containing a surface-treated pigment and a resin emulsion, wherein: the surface-treated pigment is obtained by binding a functional group, having a larger calcium index than a calcium index of 1, 2, 3-benzenetricarboxylic acid, to the surface of a pigment; and the resin emulsion is adapted so that an aqueous solution containing 1 mass % of a solid content of the resin emulsion has a conductance of 300 µS/cm or less.

    摘要： An inkjet recording method which suppresses feathering and color bleeding and is excellent in fixability to a recording medium. The inkjet recording method comprises the steps off:
    applying an ink-receiving solution prepared by dissolving in an aqueous solvent at least one metal salt having a water solubility of 0.1 mol/l or more, selected from calcium salts, magnesium salts, nickel salts and zinc salts having a valence of 2 or more, to at least the surface to be printed by using an inkjet ink or the entire surface of a recording medium; and
    printing on the metal salt adhered part by using the inkjet ink comprising at least a pigment, a resin emulsion and an aqueous solvent containing a surfactant, wherein
    a phosphorus-containing group having at least one P-O or P=O bond is bound to the surface of the pigment.
