Abstract

There is provided an ink jet ink set for sublimation transfer, including: a first ink composition containing a first disperse dye and a first dispersant; and a second ink composition containing a second disperse dye and a second dispersant, in which the first disperse dye is the same as the second disperse dye, the content of the first disperse dye in the first ink composition is equal to or greater than the content of the second disperse dye in the second ink composition, the ratio A of the content of the first disperse dye in the first ink composition to the content of the first dispersant in the first ink composition is equal to or greater than the ratio B of the content of the second disperse dye in the second ink composition to the content of the second dispersant in the second ink composition.

First claim

What is claimed is:

1. An ink jet ink set for sublimation transfer, comprising:
a first ink composition containing a first disperse dye and a first dispersant; and
a second ink composition containing a second disperse dye and a second dispersant,
wherein the first disperse dye is the same as the second disperse dye,
the content of the first disperse dye in the first ink composition is equal to or greater than the content of the second disperse dye in the second ink composition,
the ratio A of the content of the first dispersant in the first ink composition to the content of the first disperse dye in the first ink composition is equal to or greater than the ratio B of the content of the second dispersant in the second ink composition to the content of the second disperse dye in the second ink composition, and
each of the first dispersant and the second dispersant contains at least one compound selected from the group consisting of lithium and potassium salts of aromatic sulfonic acid, lithium and potassium salts of aromatic sulfonic acid-formalin condensates, lithium and potassium salts of β-naphthalenesulfonic acid, and lithium and potassium salts of β-naphthalenesulfonic acid-formalin condensates.

2. The ink jet ink set for sublimation transfer according to claim 1 ,
wherein each of the first ink composition and the second ink composition is any one of magenta ink, cyan ink, and black ink.

3. The ink jet ink set for sublimation transfer according to claim 1 ,
wherein the ratio of the content of the second disperse dye in the second ink composition to the content of the first disperse dye in the first ink composition is 5.0% to 50%.

4. The ink jet ink set for sublimation transfer according to claim 1 ,
wherein each of the ratio A and the ratio B is 50% to 200%.

5. The ink jet ink set for sublimation transfer according to claim 1 ,
wherein each of the first dispersant and the second dispersant further contains at least one compound selected from the group consisting of sodium salts of aromatic sulfonic acid, sodium salts of aromatic sulfonic acid-formalin condensates, sodium salts of β-naphthalenesulfonic acid, and sodium salts of β-naphthalenesulfonic acid-formalin condensates.

6. A method of manufacturing a dyed product, comprising:
adhering the first ink composition and the second ink composition included in the ink jet ink set for sublimation transfer according to claim 1 to an intermediate transfer medium utilizing an ink jet method; and
heating a surface of the intermediate transfer medium, the surface being adhered with the first ink composition and the second ink composition, and a dyed surface of a recording medium with these surfaces facing each other to transfer the disperse dye contained in the first ink composition and the second ink composition to the recording medium.

7. A method of manufacturing a dyed product, comprising:
adhering the first ink composition and the second ink composition included in the ink jet ink set for sublimation transfer according to claim 2 to an intermediate transfer medium utilizing an ink jet method; and
heating a surface of the intermediate transfer medium, the surface being adhered with the first ink composition and the second ink composition, and a dyed surface of a recording medium with these surfaces facing each other to transfer the disperse dye contained in the first ink composition and the second ink composition to the recording medium.

8. A method of manufacturing a dyed product, comprising:
adhering the first ink composition and the second ink composition included in the ink jet ink set for sublimation transfer according to claim 3 to an intermediate transfer medium utilizing an ink jet method; and
heating a surface of the intermediate transfer medium, the surface being adhered with the first ink composition and the second ink composition, and a dyed surface of a recording medium with these surfaces facing each other to transfer the disperse dye contained in the first ink composition and the second ink composition to the recording medium.

9. A method of manufacturing a dyed product, comprising:
adhering the first ink composition and the second ink composition included in the ink jet ink set for sublimation transfer according to claim 4 to an intermediate transfer medium utilizing an ink jet method; and
heating a surface of the intermediate transfer medium, the surface being adhered with the first ink composition and the second ink composition, and a dyed surface of a recording medium with these surfaces facing each other to transfer the disperse dye contained in the first ink composition and the second ink composition to the recording medium.

10. A method of manufacturing a dyed product, comprising:
adhering the first ink composition and the second ink composition included in the ink jet ink set for sublimation transfer according to claim 5 to an intermediate transfer medium utilizing an ink jet method; and
heating a surface of the intermediate transfer medium, the surface being adhered with the first ink composition and the second ink composition, and a dyed surface of a recording medium with these surfaces facing each other to transfer the disperse dye contained in the first ink composition and the second ink composition to the recording medium.

11. A dyed product, which is obtained utilizing the ink jet ink set for sublimation transfer according to claim 1 .

12. A dyed product, which is obtained utilizing the ink jet ink set for sublimation transfer according to claim 2 .

13. A dyed product, which is obtained utilizing the ink jet ink set for sublimation transfer according to claim 3 .

14. A dyed product, which is obtained utilizing the ink jet ink set for sublimation transfer according to claim 4 .

15. A dyed product, which is obtained utilizing the ink jet ink set for sublimation transfer according to claim 5 .
