## Abstract

Provided is a recording method of discharging ink including resin and a solvent to a heated recording medium to record an image on the recording medium by an ink jet recording apparatus, in which an absorption amount of the ink per unit mass of the recording medium is equal to or less than 1.0, and a wetting index of the recording medium measured based on JIS K6768 is equal to or more than 46, and when the wetting index is set as x, and the absorption amount of the ink per unit mass of the recording medium is set as y, a relationship of y≧0.002x−0.027 is satisfied.

## Claims

### Claim 1

A recording method of discharging ink including resin and a solvent onto a heated recording medium to record an image on the recording medium by an ink jet recording apparatus,
wherein an absorption amount of the ink per unit mass of the recording medium is equal to or less than 1.0, and a wetting index of the recording medium measured based on JIS K6768 is equal to or more than 46, and
when the wetting index is set as x, and the absorption amount of the ink per unit mass of the recording medium is set as y, a relationship of y≧0.002x−0.027 is satisfied.

### Claim 2 (depends on 1)

The recording method according to claim 1,
wherein, when the wetting index of the recording medium measured based on JIS K6768 is set as x, and the absorption amount of the ink per unit mass of the recording medium is set as y, a relationship of y≧5×1017×x−10.796 is satisfied.

### Claim 3 (depends on 1)

The recording method according to claim 1,
wherein, when the wetting index of the recording medium measured based on JIS K6768 is set as x, and the absorption amount of the ink per unit mass of the recording medium is set as y, a relationship of y≦−0.00552x+3.2429 is satisfied.

### Claim 4 (depends on 1)

The recording method according to claim 1,
wherein the recording medium includes an ink accommodation layer, and
the ink accommodation layer includes at least one kind of a material selected from a group consisting of urethane, acryl, and polyester, and/or at least two kinds of copolymer selected from a group consisting of urethane, acryl, and polyester.

### Claim 5 (depends on 1)

The recording method according to claim 1, wherein the resin included in the ink is thermoplastic resin.

### Claim 6 (depends on 1)

The recording method according to claim 1,
wherein the solvent included in the ink is at least one selected from a group consisting of 2-pyrrolidone, 1,2-hexanediol, dipropylene glycol, and propylene glycol.

### Claim 7 (depends on 1)

The recording method according to claim 1,
wherein a discharging amount of the ink with respect to the recording medium is equal to or more than 14 ng and equal to or less than 23 ng, and resolution of the image recorded on the recording medium is equal to or more than 720×720 dpi.
