## Abstract

An ink jet recording method includes attaching a reaction liquid and one or more ink jet ink compositions to a low-absorbing or non-absorbing recording medium, in which the reaction liquid contains a reactant which is a carboxylic acid or carboxylate that reacts with a component of the ink jet ink composition, the ink jet ink composition contains a resin and water, and when a deposition amount in an area in which the deposition amount of the resin is the greatest per unit area in a deposition area of the ink jet ink composition on the low-absorbing or non-absorbing recording medium is set to be 100%, the reaction liquid and the ink jet ink composition are deposited so that a mass ratio between the deposition amount of the resin and the deposition amount of the reactant (resin/reactant) in the deposition area in which the deposition amount of the resin is in a range of 20% to 100% is in a range of 1.5 to 16.

## Claims

### Claim 1

An ink jet recording method comprising:
attaching a reaction liquid and one or more ink jet ink compositions to a low-absorbing or non-absorbing recording medium,
wherein the reaction liquid contains a reactant which is a carboxylic acid or carboxylate that reacts with a component of the ink jet ink composition,
wherein the ink jet ink composition contains a resin and water,
wherein when a deposition amount in an area in which the deposition amount of the resin is the greatest per unit area in a deposition area of the ink jet ink composition on the low-absorbing or non-absorbing recording medium is set to be 100%, the reaction liquid and the ink jet ink composition are deposited so that a mass ratio between the deposition amount of the resin and the deposition amount of the reactant (resin/reactant) in the deposition area in which the deposition amount of the resin is in a range of 20% to 100% is in a range of 1.5 to 16,
wherein the resin contains a resin fine particle, and
wherein a particle diameter of the resin fine particle increases by 30 times or more in a first mixed liquid containing the resin fine particle and the reactant so that a solid content mass ratio (resin/reactant) is 3.

### Claim 2 (depends on 1)

The ink jet recording method according to claim 1,
wherein the reaction liquid and the ink jet ink composition are deposited so that the mass ratio between the deposition amount of the resin and the deposition amount of the reactant (resin/reactant) is in a range of 5.0 to 16.

### Claim 3 (depends on 1)

The ink jet recording method according to claim 1,
wherein the reaction liquid is deposited on the low-absorbing or non-absorbing recording medium in an ink jet system.

### Claim 4 (depends on 1)

The ink jet recording method according to claim 1,
wherein the resin contains a resin fine particle or a water soluble resin.

### Claim 5 (depends on 1)

The ink jet recording method according to claim 1,
wherein two or more ink jet ink compositions are deposited on the low-absorbing or non-absorbing recording medium, and
wherein the deposition amount of the resin is a total deposition amount of the resin included in the two or more ink jet ink compositions.

### Claim 6 (depends on 1)

The ink jet recording method according to claim 1,
wherein the ink jet ink composition contains a clear ink composition.

### Claim 7 (depends on 1)

The ink jet recording method according to claim 1,
wherein the deposition amount of the resin is in a range of 0.10 mg/inch2 to 1.0 mg/inch2, in a deposition area in which the deposition amount of the resin is 100%.

### Claim 8 (depends on 1)

The ink jet recording method according to claim 1,
wherein the content of the resin is in a range of 0.50% by mass to 15% by mass with respect to a total amount of the ink jet ink composition.

### Claim 9 (depends on 1)

The ink jet recording method according to claim 1,
wherein the content of the reactant is in a range of 0.50 parts by mass to 15.0 parts by mass, with respect to 100 parts by mass of a total amount of the reaction liquid.

### Claim 10 (depends on 1)

The ink jet recording method according to claim 1, wherein an amount of absorbed water of the low-absorbing or non-absorbing recording medium in a Bristow technique from a start of a contact to 30 msec is in a range of 0 mL/m2 to 10 mL/m2.
