摘要:
The present invention is an ink set for ink-jet recording using at least two kinds of inks comprising a first ink containing at least a pigment, a water-soluble solvent and water, and a second ink containing at least a pigment, a coagulant, a water-soluble solvent and water and having the absolute value of ζ-potential of not less than 10 mV. The present invention also provides an ink-jet recording method using the ink set for ink-jet recording, wherein an image is formed by applying the first ink and second ink on a recording medium so as to contact to each other. The present invention further provides an ink-jet recording apparatus comprising a recording head for ejecting at least the first ink and second ink.
