To provide a dispersible coloring material which has sufficiently high dispersion stability, causes no dropping-off of a resin component therefrom and therefore is stable for a long period of time, to realize high performances required of an inkjet recording ink in spite of the use of a water-insoluble coloring material, to remarkably improve low color developability (image density) characteristic of pigment inks, and to provide an aqueous ink which gives an effect of higher uniformity in printing parts and other effects.
The aqueous ink comprises the dispersible coloring material comprising the water-insoluble coloring material and, sticking thereto, a fine pseudoparticle of a chargeable resin smaller than the coloring material, and at least one water-soluble coloring material. An inkjet recording device, an inkjet recording method and an inkjet recorded image using the aqueous ink are also provided.
