Abstract

An ink jet recording method includes first attaching an ink composition to fabric so as to have an attached amount of 10 mg/inch 2 to 30 mg/inch 2 , and second attaching the ink composition to the fabric so as to have an attached amount of 90 mg/inch 2 to 250 mg/inch 2 , in which the ink composition includes a pigment and a resin dispersion, and a content of a resin included in the resin dispersion is 0.5 parts by mass to 2.5 parts by mass with respect to 1 part by mass of the pigment.

First claim

What is claimed is:

1. An ink jet recording method performed by using an ink jet recording apparatus including an ink composition, the method comprising:
first attaching the ink composition to fabric so as to have an attached amount of 10 mg/inch 2 to 30 mg/inch 2 ; and
second attaching the ink composition to the fabric so as to have an attached amount of 90 mg/inch 2 to 250 mg/inch 2 ,
wherein the ink composition includes a pigment and a resin dispersion, and a content of a resin included in the resin dispersion is 0.5 parts by mass to 2.5 parts by mass with respect to 1 part by mass of the pigment.

2. The ink jet recording method according to claim 1 ,
wherein the pigment includes inorganic metal fine particles, and
a content of the pigment is 5% by mass to 15% by mass with respect to a total amount of the ink composition.

3. The ink jet recording method according to claim 1 ,
wherein the resin included in the resin dispersion includes a resin having a glass transition temperature of −45° C. to 0° C.

4. The ink jet recording method according to claim 1 ,
wherein the resin dispersion includes one or more resins selected from the group consisting of an acrylic resin and a urethane resin, and
the content of the resin included in the resin dispersion is 3.5% by mass to 30% by mass with respect to the total amount of the ink composition.

5. The ink jet recording method according to claim 1 ,
wherein the content of the resin included in the resin dispersion is 1.0 part by mass to 2.5 parts by mass with respect to 1 part by mass of the pigment.

6. The ink jet recording method according claim 1 ,
wherein the ink composition further includes an organic solvent having a boiling point of 250° C. or higher.

7. The ink jet recording method according to claim 1 , further comprising:
applying a reaction solution to at least a region of the fabric to which the ink composition is attached before the first attaching of the ink composition or the second attaching of the ink composition is performed.

8. The ink jet recording method according to claim 7 ,
wherein a residual amount of a volatile component in the reaction solution per unit area of the region of the fabric to which the reaction solution is applied is 30% by mass or less with respect to a total amount of the volatile component included in the reaction solution applied per unit area of the region of the fabric after the applying of the reaction solution in the first attaching of the ink composition and the second attaching of the ink composition.

9. The ink jet recording method according to claim 7 ,
wherein the reaction solution includes one or more flocculants selected from the group consisting of a polyvalent metal salt and an organic acid.

10. The ink jet recording method according to claim 1 , further comprising:
heating and drying the fabric after the first attaching of the ink composition or the second attaching of the ink composition.

11. The ink jet recording method according to claim 1 , further comprising:
third attaching a second ink composition including one or more pigments selected from the group consisting of a color pigment and a black pigment to at least a part of the region of the fabric to which a first ink composition is attached in the second attaching of the ink composition while the ink composition is used as the first ink composition.

12. The ink jet recording method according to claim 11 , further comprising:
an attachment process (1) of performing the second attaching of the ink composition rather than performing the third attaching of the second ink composition; and
an attachment process (2) of performing the second attaching of the ink composition and the third attaching of the second ink composition,
wherein an amount of the first ink composition attached to the fabric in the second attaching of the ink composition of the attachment process (1) is larger than an amount of the first ink composition attached to the fabric in the second attaching of the ink composition of the attachment process (2).

13. The ink jet recording method according to claim 11 ,
wherein the first ink composition includes inorganic metal fine particles as the pigment and an organic solvent having a boiling point of 250° C. or higher, and the second ink composition further includes an organic solvent having a boiling point of 250° C. or higher.
