Abstract

An ink jet ink composition for textile printing including a dye containing copper or chromium 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 260 to 310 degrees.

First claim

What is claimed is:

1. An ink jet ink composition for textile printing comprising:
a dye containing copper or chromium that is selected from the group consisting of CI Reactive Blue 15 and 72, CI Direct Blue 87, and CI Acid Blue 193; and
5% to 30% 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 260 to 310 degrees.

2. The ink jet ink composition for textile printing according to claim 1 , wherein
the dye has a maximum absorption wavelength in the range of 550 to 600 nm.

3. The ink jet ink composition for textile printing according to claim 1 , wherein
the dye is C.I. Acid Blue 193.

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

5. 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.

6. The ink jet ink composition for textile printing according to claim 1 , wherein
the ink jet ink composition for textile printing contains no benzotriazole.

7. The ink jet ink composition for textile printing according to claim 1 , wherein
the ink jet ink composition for textile printing contains an alkyl polyol with a normal boiling point in the range of 180° C. to 260° C., and
the alkyl polyol content ranges from 10% to 25% by mass.

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

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

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

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

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

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

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

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 1 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 2 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 3 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 4 to the textile.

19. 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.

20. 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.
