Abstract

A printing treatment liquid composition which is to be adhered to a cloth, includes: a compound including a polyvalent carbodiimide group which has a carbodiimide group equivalent of 500 g/mol or less; and an aromatic carboxylic acid and/or its salt. According to the printing treatment liquid composition described above, a content of the compound including a polyvalent carbodiimide group with respect to a total mass of the treatment liquid composition is 1.0 to 35.0 percent by mass, a content of the aromatic carboxylic acid and/or its salt with respect to the total mass of the treatment liquid composition is 0.1 to 30.0 percent by mass, and the cloth contains fibers having hydroxy groups.

First claim

What is claimed is:

1. A printing treatment liquid composition to be adhered to a cloth, the composition comprising:
a compound including a polyvalent carbodiimide group which has a carbodiimide group equivalent of 500 g/mol or less; and
an aromatic carboxylic acid and/or its salt,
wherein a content of the compound including a polyvalent carbodiimide group with respect to a total mass of the treatment liquid composition is 1.0 to 35.0 percent by mass, a content of the aromatic carboxylic acid and/or its salt with respect to the total mass of the treatment liquid composition is 0.1 to 30.0 percent by mass, and
the cloth contains fibers having hydroxy groups.

2. The treatment liquid composition according to claim 1 ,
wherein the aromatic carboxylic acid and/or its salt includes at least one selected from the group consisting of benzoic acid, 1-naphthalene carboxylic acid, 2-naphthalene carboxylic acid, sulfoisophthalic acid, a benzoate salt, a 1-naphthalene carboxylate salt, a 2-naphthalene carboxylate salt, and a sulfoisophthalate salt.

3. The treatment liquid composition according to claim 1 ,
wherein a content ratio of the compound including a polyvalent carbodiimide group to the aromatic carboxylic acid and/or its salt in a mass ratio is 1:9 to 9:1.

4. The treatment liquid composition according to claim 1 , further comprising:
an organic acid different from the aromatic carboxylic acid.

5. An ink jet printing ink set comprising:
the treatment liquid composition according to claim 1 ; and
an ink jet printing ink composition,
wherein the ink composition contains a colorant and water.

6. The ink jet printing ink set according to claim 5 ,
wherein the colorant is a disperse dye.

7. The ink jet printing ink set according to claim 5 ,
wherein the colorant is a cyan dye.

8. A printing method comprising:
a treatment liquid composition adhesion step of adhering the treatment liquid composition according to claim 1 to the cloth.

9. An ink jet printing method comprising:
a treatment liquid composition adhesion step of adhering the treatment liquid composition of the ink set according to claim 5 to the cloth;
an ejection step of ejecting the ink composition of the ink set according to claim 5 from a recording head so as to be adhered to an intermediate transfer medium; and
a transfer step of transferring the ink composition adhered to the intermediate transfer medium to the cloth to which the treatment liquid composition is adhered.

10. An ink jet printing method comprising:
a treatment liquid composition adhesion step of adhering the treatment liquid composition of the ink set according to claim 5 to the cloth; and
an ink composition adhesion step of ejecting the ink composition of the ink set according to claim 5 from a recording head so as to be adhered to the cloth to which the treatment liquid composition is adhered.
