The invention provides an inkjet ink which exhibits, at the printing particularly on paper, excellent ink permeability to eliminate the problem of soiling immediately after printing, can be polymerized in higher sensitivity after printing and enables the recording of an image excellent in water resistance and light fastness through polymerization curing, the inkjet ink comprising a coloring fine particle dispersion containing coloring fine particles and at least one oil-soluble dye, a polymerizable hydrophobic ethylenic unsaturated monomer and a polymerization initiator, the at least one oil-soluble dye having an oxidation potential of 1.0 V or more.
