Abstract

An inkset for ink jet textile printing includes a first ink having a pigment and a resin; and a second ink having a pigment, a resin, and an emulsifier, in which the emulsifier includes at least one kind selected from an anionic emulsifier represented by the following general formula (1) and a nonionic emulsifier represented by the following general formula (2), whose HLB value is 12 or more,

R 1 —O—(CH 2 —CH 2 —O) n -A  (1), and

R 2 —O—(CH 2 —CH 2 —O) m —H  (2).

First claim

What is claimed is:

1. An ink set for ink jet textile printing, comprising:
a first ink having a white-based pigment and a urethane-based resin, the first ink not substantially including an emulsifier; and
a second ink having a pigment, a resin and an emulsifier,
wherein the emulsifier includes at least a nonionic emulsifier represented by the following general formula, whose HLB value is 12 or more,
R 2 —O—(CH 2 —CH 2 —O) m —H

(in the general formula, R 2 represents a substituted or unsubstituted hydrocarbon group having 16 or more carbon atoms and m represents an integer from 2 to 20),
wherein the white-based pigment is comprised of titanium oxide, and
wherein the urethane-based resin is comprised of at least one of a polyether type urethane resin, a polyester type urethane resin, and a polycarbonate type urethane resin.

2. The inkset for ink jet textile printing according to claim 1 , wherein the content of the emulsifier contained in the second ink is from 0.03% by mass to 0.3% by mass.

3. The inkset for ink jet textile printing according to claim 1 , wherein the first ink is used to form a base layer to which the second ink is attached on a cloth.

4. The inkset for ink jet textile printing according to claim 1 ,
wherein the pigment contained in the first ink is a white-based pigment, and
the pigment contained in the second ink is a pigment other than the white-based pigment.

5. The inkset for ink jet textile printing according to claim 4 , wherein the white-based pigment is titanium oxide.

6. The inkset for ink jet textile printing according to claim 1 , wherein the coating elongation of the resin contained in the first ink and the coating elongation of the resin contained in the second ink are in the range of 400% to 1200%.

7. The inkset for ink jet textile printing according to claim 1 , wherein both the resin contained in the first ink and the resin contained in the second ink contain at least one kind selected from a urethane-based resin and an acrylic resin.

8. An ink jet textile printing method using the inkset for ink jet textile printing according to claim 1 , comprising:
forming a first image formed by the first ink by attaching the first ink to a cloth; and
forming a second image formed by the second ink by attaching the second ink to the first image.

9. The ink jet textile printing method according to claim 8 , wherein the forming of the second image is performed when a residual rate of a volatile component is 30% or more in a case in which the weight of the volatile component contained in the first ink used to form the first image is set to 100%.

10. The ink jet textile printing method according to claim 8 , wherein a coagulant which reacts with a component contained in the first ink is provided in a range of the cloth on which the first image is formed.

11. The ink jet textile printing method according to claim 8 , wherein the attached amount of the first ink attached to the cloth is 180 mg/inch 2 or more in the forming of the first image.

12. The inkset for ink jet textile printing according to claim 1 , wherein the first ink and the second ink are ink jet textile printing inks.

13. An ink set for ink jet textile printing, comprising:
a first ink having a white-based pigment and a urethane-based resin, the first ink not substantially including an emulsifier; and
a second ink having a pigment, a resin and an emulsifier,
wherein the emulsifier includes a nonionic emulsifier represented by the following general formula, whose HLB value is 12 or more,
R 2 —O—(CH 2 —CH 2 —O) m —H

(in the general formula, R 2 represents a substituted or unsubstituted hydrocarbon group having 16 or more carbon atoms and m represents an integer from 2 to 20),
wherein the white-based pigment is comprised of titanium oxide, and
wherein the urethane-based resin is comprised of at least one of a polyether type urethane resin, a polyester type urethane resin, and a polycarbonate type urethane resin.

14. The inkset for ink jet textile printing according to claim 13 , wherein the content of the emulsifier contained in the second ink is from 0.03% by mass to 0.3% by mass.

15. The inkset for ink jet textile printing according to claim 13 , wherein the first ink is used to form a base layer to which the second ink is attached on a cloth.

16. The inkset for ink jet textile printing according to claim 13 , wherein the pigment contained in the first ink is a white-based pigment, and the pigment contained in the second ink is a pigment other than the white-based pigment.

17. The inkset for ink jet textile printing according to claim 16 , wherein the white-based pigment is titanium oxide.

18. The inkset for ink jet textile printing according to claim 13 , wherein the coating elongation of the resin contained in the first ink and the coating elongation of the resin contained in the second ink are in the range of 400% to 1200%.

19. The inkset for ink jet textile printing according to claim 13 , wherein both the resin contained in the first ink and the resin contained in the second ink contain at least one kind selected from a urethane-based resin and an acrylic resin.

20. An ink jet textile printing method using the inkset for ink jet textile printing according to claim 13 , comprising:
forming a first image formed by the first ink by attaching the first ink to a cloth; and
forming a second image formed by the second ink by attaching the second ink to the first image.

21. The ink jet textile printing method according to claim 20 , wherein the forming of the second image is performed when a residual rate of a volatile component is 30% or more in a case in which the weight of the volatile component contained in the first ink used to form the first image is set to 100%.

22. The ink jet textile printing method according to claim 20 , wherein a coagulant which reacts with a component contained in the first ink is provided in a range of the cloth on which the first image is formed.

23. The ink jet textile printing method according to claim 20 , wherein the attached amount of the first ink attached to the cloth is 180 mg/inch2 or more in the forming of the first image.

24. The inkset for ink jet textile printing according to claim 13 , wherein the first ink and the second ink are ink jet textile printing inks.
