Abstract

An ink jet ink composition for textile printing including a dye and 5% to 30% by mass of a cyclic amide that is liquid at normal temperature and that has a normal boiling point in the range of 190° C. to 260° C., wherein the hue angle ∠h° defined by the CIELAB color space on a recording medium ranges from 15 to 80 degrees.

First claim

What is claimed is:

1. An ink jet ink composition for textile printing, comprising:
a dye;
10% to 25% by mass of an alkyl polyol with a normal boiling point in the range of 180° C. to 260° C.; and
7% to 15% by mass of a cyclic amide that is liquid at normal temperature and has a normal boiling point in the range of 190° C. to 260° C.,
wherein a hue angle ∠h° defined by a CIELAB color space on a recording medium ranges from 15 to 80 degrees.

2. The ink jet ink composition for textile printing according to claim 1 , wherein
the hue angle ∠h° defined by a CIELAB color space on a recording medium ranges from 20 to 75 degrees.

3. The ink jet ink composition for textile printing according to claim 1 , wherein
the dye has a maximum absorption wavelength in the range of 350 to 450 nm.

4. The ink jet ink composition for textile printing according to claim 1 , wherein
the dye is at least one of C.I. Reactive Orange 35, C.I. Reactive Orange 12, C.I. Reactive Orange 99, C.I. Acid Brown 298, and C.I. Acid Orange 56.

5. The ink jet ink composition for textile printing according to claim 1 , wherein
the dye content ranges from 3% to 15% by mass.

6. The ink jet ink composition for textile printing according to claim 1 , wherein
the ink jet ink composition for textile printing has a pH in the range of 6 to 10.

7. An ink set comprising the ink jet ink composition for textile printing according to claim 1 .

8. An ink set comprising the ink jet ink composition for textile printing according to claim 2 .

9. An ink set comprising the ink jet ink composition for textile printing according to claim 3 .

10. An ink set comprising the ink jet ink composition for textile printing according to claim 4 .

11. An ink set comprising the ink jet ink composition for textile printing according to claim 5 .

12. An ink set comprising the ink jet ink composition for textile printing according to claim 6 .

13. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 1 to the textile.

14. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 2 to the textile.

15. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 3 to the textile.

16. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 4 to the textile.

17. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 5 to the textile.

18. A recording method comprising:
a pretreatment process of applying a pretreatment composition containing at least one of an alkaline agent, an acid, and a hydrotropic agent to a textile; and
a printing process of applying the ink jet ink composition for textile printing according to claim 6 to the textile.
