Abstract

An ink jet ink composition for sublimation transfer includes dye A and a dye B, in which the dye A is a disperse dye which has a molecular weight of 380 or less and an anthraquinone skeleton having a water-soluble group in a molecule, the dye B is a disperse dye which has a molecular weight of 400 or greater, and in the ink jet ink composition for sublimation transfer, dye solubility of the dye A is greater than dye solubility of the dye B.

First claim

What is claimed is:

1. An ink jet ink composition for sublimation transfer, comprising:

2. The ink jet ink composition for sublimation transfer according to claim 1 , wherein in the ink jet ink composition for sublimation transfer, the dye solubility of the dye B is 10.sup.−3 or less.

3. A method of manufacturing dyed products, comprising: attaching the ink jet ink composition for sublimation transfer according to claim 2 on an intermediate transfer medium using an ink jet method; and transferring a disperse dye included in the ink jet ink composition for sublimation transfer to a recording medium by heating in a state in which a surface of the intermediate transfer medium on which the ink jet ink composition for sublimation transfer is attached and a dye surface of the recording medium face each other.

4. The method of manufacturing dyed products according to claim 3 , wherein a heating temperature in the transferring is 160.degree. C. to 220.degree. C.

5. An ink set, comprising: a first ink composition; and a second ink composition, wherein the first ink composition includes at least one kind of the ink jet ink composition for sublimation transfer according to claim 2 , the second ink composition is an ink jet black ink composition for sublimation transfer including at least one kind selected from a group consisting of a dye A which is a disperse dye which has a molecular weight of 380 or less and an anthraquinone skeleton having a water-soluble group in a molecule, a dye B which is a disperse dye which has a molecular weight of 400 or greater, and a dye C, the dye C is a disperse dye which has a molecular weight of 380 or less and does not have the anthraquinone skeleton having the water-soluble group in the molecule, and in the second ink composition, dye solubility of the dye A is greater than dye solubilities of the dyes B and C, and dye solubility of the dye C is 10.sup.−3 or less.

6. The ink jet ink composition for sublimation transfer according to claim 1 , wherein the dye B is a disperse dye which has the anthraquinone skeleton in a molecule.

7. A method of manufacturing dyed products, comprising: attaching the ink jet ink composition for sublimation transfer according to claim 6 on an intermediate transfer medium using an ink jet method; and transferring a disperse dye included in the ink jet ink composition for sublimation transfer to a recording medium by heating in a state in which a surface of the intermediate transfer medium on which the ink jet ink composition for sublimation transfer is attached and a dye surface of the recording medium face each other.
