Abstract

An ink jet printing method includes an ejection step of ejecting an ink jet ink composition containing a sublimation dye from a recording head so as to be adhered to an intermediate transfer medium A; and a transfer step of transferring the sublimation dye adhered to the intermediate transfer medium A by sublimation to a cloth B. In the ink jet printing method described above, an affinity parameter Ln (gamma) at 25° C. calculated by a COSMO-RS method between the sublimation dye and a member of a surface of the cloth B to which the sublimation transfer is performed is 5 or less.

First claim

What is claimed is:

1 . An ink jet printing method comprising:
an ejection step of ejecting an ink jet ink composition containing at least one type of sublimation dye from a recording head so as to be adhered to an intermediate transfer medium A; and a transfer step of transferring the sublimation dye adhered to the intermediate transfer medium A by sublimation to a cloth B, wherein when an affinity parameter Ln (gamma) at 25° C. between the sublimation dye and a member of a surface of the cloth B to which the sublimation transfer is performed is calculated by a COSMO-RS method, the affinity parameter Ln (gamma) at 25° C. is 5 or less and wherein when the member includes a poly(ethylene terephthalate), a content of the poly(ethylene terephthalate) with respect to a total mass of the cloth B is more than 0 to 5 percent by mass.

2 . The ink jet printing method according to claim 1 , wherein the Ln (gamma) is 3 or less.

3 . The ink jet printing method according to claim 1 , wherein the Ln (gamma) is 0 or less.

4 . The ink jet printing method according to claim 1 , wherein the member includes at least one selected from the group consisting of a cotton and a polypropylene.

5 . The ink jet printing method according to claim 1 , wherein the ink jet ink composition contains at least two types of the sublimation dyes, and
the Ln's (gamma) with respective to the respective sublimation dyes are each 5 or less.

6 . The ink jet printing method according to claim 1 , further comprising, before the transfer step:
a pre-treatment step of adhering a pre-treatment liquid composition in advance to the surface of the cloth B to which the sublimation transfer is performed, wherein the pre-treatment liquid composition contains a resin including a dicarboxylic acid compound and a diol compound as constituent units.

7 . The ink jet printing method according to claim 6 ,
wherein the dicarboxylic acid compound includes terephthalic acid and isophthalic acid, the diol compound includes ethylene glycol, and a content of the ethylene glycol with respect to a total mass of the diol compound is 30 to 100 percent by mole.

8 . The ink jet printing method according to claim 7 ,
wherein the diol compound further includes a neopentyl glycol, and a content of the neopentyl glycol with respect to the total mass of the diol compound is more than 0 to 70 percent by mole.

9 . The ink jet printing method according to claim 1 ,
wherein the sublimation dye includes at least one selected from the group consisting of Disperse Orange 25, Disperse Blue 360, Disperse Blue 359, Disperse Yellow 54, Disperse Yellow 232, Solvent Orange 60, Disperse Violet 28, Disperse Red 60, and Disperse Brown 27.

10 . The ink jet printing method according to claim 6 ,
wherein the pre-treatment liquid composition further contains a cross-linking agent.

11 . An ink jet printing set comprising:
an ink jet ink composition containing a sublimation dye; and a cloth B to which the sublimation dye is transferred by sublimation, wherein when an affinity parameter Ln (gamma) at 25° C. between the sublimation dye and a member of a surface of the cloth B to which the sublimation transfer is performed is calculated by a COSMO-RS method, the affinity parameter Ln (gamma) at 25° C. is 5 or less, and wherein when the member includes a poly(ethylene terephthalate), a content of the poly(ethylene terephthalate) with respect to a total mass of the cloth B is more than 0 to 5 percent by mass.

12 . An ink jet printing set comprising:
an ink jet ink composition containing a sublimation dye; and a pre-treatment liquid composition, wherein the pre-treatment liquid composition is a composition to perform a pre-treatment on a cloth B to which the sublimation dye is transferred by sublimation, the pre-treatment liquid composition contains resin particles, when an affinity parameter Ln (gamma) at 25° C. between the sublimation dye and the resin particles is calculated by a COSMO-RS method, the affinity parameter Ln (gamma) at 25° C. is 5 or less, and when the member includes a poly(ethylene terephthalate), a content of the poly(ethylene terephthalate) with respect to a total mass of the cloth B is more than 0 to 5 percent by mass.
