Abstract

A recording method includes a colored ink adhering step of adhering a colored ink composition to an intermediate transfer medium by an ink jet method to form a recording region A, a clear ink adhering step of adhering a clear ink composition to at least a portion of a recording medium to form a region B, and a transfer step of transferring an image formed in the recording region A to the region B of the recording medium by heating in a state where the recording region A of the intermediate transfer medium faces the region B of the recording medium. The colored ink composition contains a sublimation dye, a water-soluble organic solvent, and water, and the intermediate transfer medium has a peeling layer containing a resin having a glass transition point of 100° C. or more and 200° C. or less.

First claim

What is claimed is:

1. A recording method comprising:
a colored ink adhering step of adhering a colored ink composition to an intermediate transfer medium by an ink jet method to form a recording region A;
a clear ink adhering step of adhering a clear ink composition to at least a portion of a recording medium to form a region B; and
a transfer step of transferring an image formed in the recording region A to the region B of the recording medium by overlapping the recording region A to the region B and heating in a state where the clear ink in the region B contains a predetermined amount of liquid,
wherein the colored ink composition contains a sublimation dye, a water-soluble organic solvent, and water; and
the intermediate transfer medium has a peeling layer containing a resin having a glass transition point of 100° C. or more and 200° C. or less.

2. The recording method according to claim 1 , wherein the heating temperature in the transfer step is 160° C. to 190° C.

3. The recording method according to claim 1 , wherein the resin contained in the peeling layer contains one or more selected from the group consisting of polyester, polystyrene, polyacryl, polystyrene-acrylic resin, poly(ethylene-vinyl acetate), and a polymer based on diallyl methyl ammonium chloride.

4. The recording method according to claim 1 , wherein the absolute value of difference between the surface tension S 1 of the colored ink composition and the surface tension S 2 of the clear ink composition is within 5.0.

5. The recording method according to claim 1 , wherein the colored ink composition and the clear ink composition contain the same one or more water-soluble organic solvents.

6. The recording method according to claim 1 , wherein the recording medium is a fabric containing cotton.

7. The recording method according to claim 1 , wherein the transfer step is performed in a state where the amount of the clear ink composition adhered to the region B is 1.0 mg/inch 2 or more.

8. The recording method according to claim 1 , wherein when the recording region A has a recording region Al where the amount of the colored ink composition adhered thereto is less than 2.0 mg/inch 2 , in the clear ink adhering step, the clear ink composition is adhered to a region B1, facing the recording region A1, in the region B.

9. The recording method according to claim 1 , wherein when the recording region A has a recording region A 2 where the amount of the colored ink composition adhered thereto is 2.0 mg/inch 2 or more, in the clear in adhering step, the clear ink composition is not adhered to a region B2, facing the recording region A2, in the region B.

10. The recording method according to claim 1 , wherein the total amount of the colored ink composition and the clear ink composition adhered to the facing recording region A and region B, respectively, is 3.0 to 32 mg/inch 2 .

11. The recording method according to claim 1 , wherein the clear ink composition contains a water-soluble organic solvent and water.
