Abstract

Provided is an ink jet ink for printing including: water; a first dye; and a second dye, in which the first dye is C.I. Acid Orange 33, and the second dye is one or two kinds selected from C.I. Acid Orange 56 and C.I. Acid Orange 94.

First claim

What is claimed is:

1. An ink jet ink for printing, comprising:
water;
a first dye; and
a second dye,
wherein the first dye is C.I. Acid Orange 33, and
wherein the second dye is one or two kinds selected from C.I. Acid Orange 56 and C.I. Acid Orange 94.

2. The ink jet ink for printing according to claim 1 ,
wherein the ratio of the content of the first dye to the content of the second dye is in a range of (the former):(the latter)=11:1 to 1:1 by mass.

3. The ink jet ink for printing according to claim 1 ,
wherein the ratio of the content of the first dye to the content of the second dye is in a range of (the former):(the latter)=6.5:1 to 1.2:1 by mass.

4. The ink jet ink for printing according to claim 1 ,
wherein the total content of the first dye and the second dye is 5.0 mass % or more.

5. A printing method comprising:
applying the ink jet ink for printing according to claim 1 to fabric for printing; and
heating the fabric to fix a dye.

6. An ink jet ink set comprising at least:
a first ink;
a second ink;
a third ink; and
a fourth ink,
wherein the first ink contains water and a first dye, and a hue angle H calculated from spectral transmittance of a diluted solution which is diluted to 1000 times by water is 90° to 120°,
wherein the second ink contains water and a second dye, and a hue angle H calculated from the spectral transmittance of the diluted solution which is diluted to 1000 times by water is 0° to 30°,
wherein the third ink contains water and a third dye, and a hue angle H calculated from the spectral transmittance of the diluted solution which is diluted to 1000 times by water is 220° to 250°,
wherein the fourth ink contains water and 5 mass % or more of a fourth dye with respect to a total 100 mass % of the fourth ink, and a hue angle H calculated from the spectral transmittance of the diluted solution which is diluted to 1000 times by water is 50° to 70°, and the pH is 7.0 to 8.0, and
wherein the fourth dye contains at least one of C.I. Acid Orange 33 and C.I. Acid Orange 94.

7. The ink jet ink set according to claim 6 ,
wherein a dissolved nitrogen amount of the fourth ink is 6 ppm or less.

8. The ink jet ink set according to claim 6 ,
wherein the ratio of the content of the water to the content of the fourth dye in the fourth ink is 11.00 to 13.00 by mass.

9. The ink jet ink set according to claim 6 ,
wherein the fourth dye contains C.I. Acid Orange 33 and C.I. Acid Orange 94, and
wherein the ratio of the content of the C.I. Acid Orange 33 to the content of the C.I. Acid Orange 94 is 1 to 10 by mass.

10. The ink jet ink set according to claim 6 , further comprising:
a fifth ink,
wherein the fifth ink contains the water and a fifth dye, and a hue angle H calculated from the spectral transmittance of the diluted solution which is diluted to 1000 times by water is 275° to 295°, and
wherein the fifth dye contains C.I. Acid Blue 140 and C.I. Acid Violet 48.

11. The ink jet ink set according to claim 6 ,
wherein the content of the C.I. Acid Blue 140 is 6.0 mass % or more with respect to a total 100 mass % of the fifth ink, and
wherein the content of the C.I. Acid Violet 48 is 0.5 mass % to 1.6 mass % with respect to a total 100 mass % of the fifth ink.

12. The ink jet ink set according to claim 6 ,
wherein the ink jet ink set is filled in a container containing polyolefin.

13. The ink jet ink set according to claim 6 ,
wherein the container has an ink storage chamber formed of a flexible member.
