## Abstract

An image recording method includes applying an ink containing a pigment in a dispersion to a region of a recording medium, and applying a liquid composition capable of destabilizing the dispersion of the pigment in the ink to the recording medium so as to cover at least part of the region of the recording medium. The ink further contains polymer particles, and at least one surfactant selected from the group consisting of the compounds expressed by General Formula (1) and the compounds expressed by General Formula (2). In the ink, the content of the polymer particles is 3% by mass or more and 20% by mass or less relative to the total mass of the ink, and the mass ratio of the polymer particles to the surfactant is 1 or more and 10 or less.

## Claims

### Claim 1

An image recording method comprising:
applying an ink comprising a pigment to a region of a recording medium, and
applying a liquid composition capable of destabilizing the dispersion of the pigment to the recording medium so as to cover at least part of the region of the recording medium;
wherein the ink comprises a polymer particle and at least one surfactant selected from the group consisting of the compounds expressed by General Formula (1) and the compounds expressed by General Formula (2),
wherein a content of the polymer particle is 3% by mass or more and 20% by mass or less relative to the total mass of the ink, and
wherein the mass ratio of the content of the polymer particle to the content of the surfactant in the ink is 1 or more and 10 or less,
wherein “l+n” is 3 or more and 45 or less, and m is 16 or more and 57 or less, and
wherein “p+r” is 25 or more and 50 or less, and q is 8 or more and 25 or less.

### Claim 2 (depends on 1)

The image recording method according to claim 1, wherein the content of the surfactant in the ink is 0.2% by mass or more and 5% by mass or less relative to the total mass of the ink.

### Claim 3 (depends on 1)

The image recording method according to claim 1, wherein the mass ratio of the content of the polymer particle to the content of the surfactant in the ink is 1.5 or more and 5.0 or less.

### Claim 4 (depends on 1)

The image recording method according to claim 1, wherein the polymer particle in the ink is an anionic polymer particle.
