Abstract

Disclosed is a recording method including attaching a reaction solution which forms a recording region S1 by attaching a reaction solution which includes an aggregating agent which is able to aggregate components of a color ink composition to a target recording medium with an attachment amount of 100 nmol/inch2 to 1500 nmol/inch2 of the aggregating agent, and attaching a color ink composition which forms a recording region S2 by attaching the color ink composition which includes a coloring material and a resin to the recording region S1 within 30 seconds of attaching the reaction solution.

First claim

What is claimed is:

1. A recording method comprising:
attaching a reaction solution which forms a recording region S 1 by attaching a reaction solution which includes an aggregating agent which is able to aggregate components of a color ink composition to a target recording medium; and
attaching a color ink composition which forms a recording region S 2 by attaching the color ink composition which includes a coloring material and a resin to the recording region S 1 within 30 seconds of attaching the reaction solution,
wherein, in the attaching of the color ink composition, the recording region S 2 is formed by attaching the color ink composition which includes a coloring material and a resin to the recording region S 1 in a state where, with respect to a total mass of 100 mass % of volatile components which are included in the reaction solution before attachment, a volatile component residual ration of the reaction solution on the recording region S 1 is 90 mass % or more.

2. The recording method according to claim 1 ,
wherein, in the attaching of the reaction solution, the reaction solution is discharged as liquid droplets and attached to the target recording medium with an attachment density of 600 dpi or more ×600 dpi or more.

3. The recording method according to claim 1 ,
wherein the target recording medium is a low-absorptive recording medium which is a coated paper having a quantity of water absorption at 30 msec from the start of contact is 5 mL/m 2 or more to 10 mL/m 2 or less according to the Bristow method.

4. The recording method according to claim 1 ,
wherein the content of the aggregating agent is from 0.090 mol/1000 g to 0.91 mol/1000 g of the reaction solution.

5. The recording method according to claim 1 ,
wherein a component of the color ink composition which is aggregated by the aggregating agent includes at least one of a pigment, the pigment being included in the coloring material, and the resin.

6. The recording method according to claim 1 ,
wherein the aggregating agent includes at least one of a multivalent metal salt or an organic acid.

7. The recording method according to claim 1 ,
wherein, in the attaching of the reaction solution and the attaching of the color ink composition, attachment is performed by performing one scanning with an ink jet head, which discharges the reaction solution or the color ink composition from the ink jet head while changing relative positions of the ink jet head and the target recording medium.

8. The recording method according to claim 1 ,
wherein a temperature of the recording region S 1 of the target recording medium is held at 38° C. or less from the attaching of the reaction solution to the attaching of the color ink composition.

9. The recording method according to claim 1 , wherein an attachment amount of the aggregating agent is from 100 nmol/inch 2 to 936 nmol/inch 2 .

10. The recording method according to claim 1 , wherein the color ink composition is attached to the recording region S 1 within 10 seconds of attaching the reaction solution, which forms the recording region S 2 .

11. The recording method according to claim 1 , wherein a temperature of the heated target recording medium is 40° C. or less.

12. The recording method according to claim 1 , wherein the color ink composition is attached to the recording region S 1 within 20 seconds of attaching the reaction solution.

13. The recording method according to claim 1 , wherein the volatile component residual ratio of the reaction solution on the recording region S 1 is 30 mass % to 90 mass %.

14. The recording method according to claim 1 , wherein an attachment amount of the color ink composition is 1.0 mg/inch 2 to 10.0 mg/inch 2 .

15. The recording medium according to claim 1 ,
wherein, in the attaching a color ink composition, the recording region S 2 is formed by attaching the color ink composition which includes a coloring material and a resin to the recording region S 1 in a state where, with respect to a total mass of 100 mass % of volatile components which are included in the reaction solution before attachment, a volatile component residual ratio of the reaction solution on the recording region S 1 is 30 mass % or more.

16. The recording medium according to claim 1 , wherein the recording method comprises heating the target recording medium for drying the reaction liquid before attaching the color ink composition or during attaching the color ink composition.

17. The recording medium according to claim 1 , wherein the aggregating agent is a multivalent metal salt.

18. The recording medium according to claim 1 , wherein the aggregating agent is a multivalent metal salt, the multivalent metal salt being a calcium salt.

19. The recording medium according to claim 18 , wherein the calcium salt is a salt of formic acid, a salt of acetic acid, sulfate, nitrate, chloride, or thiocyanate.

20. The recording medium according to claim 1 , wherein before the attaching the color ink composition, the target recording medium to which the reaction solution is attached is a normal temperature without heating.
