Abstract
An ink jet recording method including the steps of a first recording step for applying a first ink to a recording medium and a second recording step for applying a second ink to the recording medium so as to overlap at least a region provided with the first ink, wherein the first ink is an aqueous ink containing silver particles, the second ink is an aqueous ink containing a dye, a time difference between applications of the first ink and the second ink to the recording medium is 1 sec or more to 7,200 sec or less, and the dye is a predetermined dye.
Claims9
An ink jet recording method comprising the steps of:
- a first step for applying a first ink to a recording medium;
- and
- a second step for applying a second ink to the recording medium so as to overlap at least a region provided with the first ink,
- wherein the first ink is an aqueous ink comprising silver particles,
- the second ink is an aqueous ink comprising a dye,
- a time difference between applications of the first ink and the second ink to the recording medium is 1 sec or more to 7,200 sec or less, and
- the intermolecular distance d-value of the dye measured by a small-angle X-ray scattering method is 5.9 nm or more, and the ratio of the peak area to the peak area of C.I. Acid Red 249 is 1.1 times or more.
An ink jet recording apparatus comprising a device to apply a second ink after a first ink is applied,
- wherein the first ink is an aqueous ink comprising silver particles,
- the second ink is an aqueous ink comprising a dye,
- a time difference between applications of the first ink and the second ink to the recording medium is 1 sec or more to 7,200 sec or less, and
- the intermolecular distance d-value of the dye measured by a small-angle X-ray scattering method is 5.9 nm or more, and, in addition, the ratio of the peak area to the peak area of C.I. Acid Red 249 is 1.1 times or more.
