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.
An ink set for ink-jet recording using at least two kinds of inks, wherein:
An ink-jet recording method using 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 an absolute value of ζ-potential of not less than 10 mV, wherein an image is formed by applying the first ink and second ink on a recording medium so as to contact each other, and wherein a number of particles having a diameter of not less than 5 μm in a mixed solution of equal amounts by mass of the first and second inks is not less than 1,000 particles/μL.
An ink-jet recording apparatus comprising a recording head for ejecting each ink in an ink set for ink-jet recording, the ink set for ink-jet recording comprising at least two kinds of inks, wherein:
