Abstract

An inkjet treatment liquid contains emulsified particles containing a silicone oil and an aqueous medium, in which a percentage content of the silicone oil is 7% by mass or more and 15% by mass or less.

First claim

The invention claimed is:

1. An inkjet treatment liquid, comprising:
emulsified particles containing a silicone oil; and
an aqueous medium,
wherein a percentage content of the silicone oil is 7% by mass or more and 15% by mass or less, and
the inkjet treatment liquid is a treatment liquid for post-processing.

2. The inkjet treatment liquid according to claim 1 , wherein the percentage content of the silicone oil is 10% by mass or more and 13% by mass or less.

3. The inkjet treatment liquid according to claim 1 , wherein the silicone oil includes at least an ionic functional group-containing silicone oil.

4. The inkjet treatment liquid according to claim 3 , wherein the ionic functional group-containing silicone oil is a carboxy-modified silicone oil.

5. The inkjet treatment liquid according to claim 1 , wherein the silicone oil includes at least an unmodified silicone oil.

6. The inkjet treatment liquid according to claim 5 , wherein the unmodified silicone oil is dimethylpolysiloxane.

7. The inkjet treatment liquid according to claim 1 , wherein the silicone oil includes an ionic functional group-containing silicone oil and an unmodified silicone oil.

8. The inkjet treatment liquid according to claim 7 , wherein the ionic functional group-containing silicone oil is a carboxy-modified silicone oil.

9. The inkjet treatment liquid according to claim 1 , wherein the emulsified particles include first emulsified particles containing an ionic functional group-containing silicone oil and second emulsified particles containing an unmodified silicone oil.

10. The inkjet treatment liquid according to claim 1 , wherein the silicone oil includes an ionic functional group-containing silicone oil and an unmodified silicone oil, and
the ratio of the mass of the ionic functional group-containing silicone oil to the mass of the unmodified silicone oil is 0.5 or more and less than 1.0.

11. The inkjet treatment liquid according to claim 1 , which is for textile printing.

12. An inkjet textile printing apparatus, comprising:
a recording head configured to eject ink onto an image forming region of a textile printing target;
a processing head configured to eject a treatment liquid onto at least the image forming region of the textile printing target; and
a cartridge filled with the treatment liquid,
wherein the treatment liquid is the inkjet treatment liquid according to claim 9 .

13. The inkjet textile printing apparatus according to claim 12 , wherein the ink contains a pigment.

14. The inkjet textile printing apparatus according to claim 12 , further comprising a heating unit configured to heat the textile printing target on which the ink and the treatment liquid are ejected.

15. An inkjet textile printing method, comprising:
ejecting ink from a recording head onto an image forming region of a textile printing target; and
ejecting a treatment liquid from a processing head onto at least the image forming region of the textile printing target,
wherein the treatment liquid is the inkjet treatment liquid according to claim 1 .

16. The inkjet textile printing method according to claim 15 , wherein an amount of the inkjet treatment liquid ejected is 5 g/m 2 or more and 30 g/m 2 or less.

17. The inkjet textile printing method according to claim 16 , wherein the amount of the inkjet treatment liquid ejected is 5 g/m 2 or more and 10 g/m 2 or less.

18. The inkjet textile printing method according to claim 15 , wherein the ink contains a pigment.

19. The inkjet textile printing method according to claim 15 , further comprising heating at least the image forming region of the textile printing target on which the ink and the treatment liquid are ejected.
