Abstract:
The present invention performs printing with an aqueous ink-jet ink composition on non-ink-absorbing or lowly-ink-absorbing media having poor wettability. The aqueous ink-jet ink composition comprises a pigment, water, an alkanediol having 6-10 carbon atoms, and a resin emulsion, wherein the proportion by mass of the alkanediol to the ink-jet ink composition has a minimum value of 10%. The ink-jet recording method comprises adhering an aqueous ink-jet ink composition to a non-ink-absorbing or lowly-ink-absorbing medium to conduct printing, wherein the ink-jet ink composition is one obtained by dispersing a solute comprising a pigment and a resin emulsion in water containing an alkanediol having 6-10 carbon atoms, the ink-jet ink composition being delivered for printing to the non-ink-absorbing or lowly-ink-absorbing medium heated to 50-60°C.
