Abstract

An ink jet recording method includes heating a recording medium, and discharging a water-based ink composition which contains a resin fine particle, water, a water-soluble organic solvent, and a surfactant from an ink jet head so as to adhere the water-based ink composition to the heated recording medium in the heating, in which the water-based ink composition has a contact angle of the water-based ink composition with respect to an ink film obtained by drying the water-based ink composition is equal to or larger than 25° at 100 ms, and is equal to or larger than 20° at 1000 ms.

First claim

wherein the water-based ink composition has a contact angle of the water-based ink composition with respect to an ink film obtained by drying the water-based ink composition is equal to or larger than 25° at 100 ms, and is equal to or larger than 20° at 1000 m,
the water-based ink composition contains, as a surfactant, an acetylene glycol surfactant and at least one of a silicone surfactant and a fluorine surfactant, and
the content of at least one of the silicone surfactant and the fluorine surfactant is 0.8% by mass or more with respect to a total amount of an ink composition.

2. The ink jet recording method according to claim 1 ,
wherein in the water-based ink composition, a content of the water-soluble organic solvent having a standard boiling point of equal to or higher than 280° C. is equal to or less than 3% by mass.

3. The ink jet recording method according to claim 1 ,
wherein the content of the at least one of the silicone surfactant and the fluorine surfactant is in the range of 0.8% to 5% by mass with respect to a total amount of an ink composition, and a content of the acetylene glycol surfactant is in the range range of 0.1% to 1.5% by mass with respect to a total amount of an ink composition.

4. The ink jet recording method according to claim 1 ,
wherein the water-based ink composition contains a nitrogen-containing solvent as the water-soluble organic solvent.

5. The ink jet recording method according to claim 1 ,
wherein a surface temperature of a nozzle surface at the time of adhering the water-based ink composition is equal to or lower than 55° C.

6. The ink jet recording method according to claim 1 ,
wherein the ink jet head has a step in a flow path through which ink passes from a pressure chamber to a nozzle.

7. The ink jet recording method according to claim 1 ,
wherein the pressure chamber of the ink jet head includes an ink storage portion for storing ink in a direction extended from an outflow port in an ink movement direction in which a supply port for supplying ink to the pressure chamber and the outflow port for discharging the ink from the pressure chamber are connected to each other.

8. The ink jet recording method according to claim 1 , which is performed by using a serial printer,
wherein a time during which the recording medium faces the ink jet head during one main scanning is equal to or shorter than 12 seconds.

9. The ink jet recording method according to claim 1 ,
wherein in the water-based ink composition, a content (% by mass) ratio (water-soluble organic solvent/surfactant) of the water-soluble organic solvent to the surfactant is in a range of 3 to 17.

10. The ink jet recording method according to claim 1 ,
wherein a resin of the resin fine particle contained in the water-based ink composition includes a resin having a glass transition point of equal to or higher than 40° C.

11. A recording apparatus which performs recording by the ink jet recording method according to claim 1 ,
wherein the recording apparatus controls recording to be performed for one hour or longer without performing maintenance in which ink is discharged from an ink jet head by a unit other than a pressure generation unit for recording by discharging ink.

12. A recording apparatus which performs recording by the ink jet recording method according to claim 2 ,
wherein the recording apparatus controls recording to be performed for one hour or longer without performing maintenance in which ink is discharged from an ink jet head by a unit other than a pressure generation unit for recording by discharging ink.

13. A recording apparatus which performs recording by the ink jet recording method according to claim 3 ,
wherein the recording apparatus controls recording to be performed for one hour or longer without performing maintenance in which ink is discharged from an ink jet head by a unit other than a pressure generation unit for recording by discharging ink.

14. A recording apparatus which performs recording by the ink jet recording method according to claim 4 ,
wherein the recording apparatus controls recording to be performed for one hour or longer without performing maintenance in which ink is discharged from an ink jet head by a unit other than a pressure generation unit for recording by discharging ink.
