Abstract

There is provided an ink jet recording method for printing a pigment in which a pigment printing ink composition including at least pigment as a colorant is discharged from a nozzle opening as an ink droplet having an amount of the ink of the ink droplet of 9 ng or less with an average discharging speed V of 5 m/s or greater at a distance in the range of 0.5 mm to 1.0 mm in the direction from the nozzle opening to cloth, and whereby the pigment printing ink composition is adhered to the cloth.

First claim

What is claimed is:

1. An ink jet recording method for printing a pigment, wherein:
a pigment printing ink composition including at least pigment as a colorant is discharged from a nozzle opening as an ink droplet with an average discharging speed of 5 m/s or greater at a distance in the range of 0.5 mm to 1.0 mm in a direction from the nozzle opening to a cloth, and the pigment printing ink composition is adhered to the cloth, wherein
the pigment printing ink composition includes a resin dispersion in which the resin is dispersed in a dispersion medium as fine particles, and
a content of resin, in a resin dispersion included in the pigment printing ink composition, is 3% by mass or greater with respect to the total mass of the ink composition.

2. The ink jet recording method for printing a pigment according to claim 1 , wherein the distance between the nozzle opening and the cloth is in the range of 2.0 mm to 5.0 mm.

3. The ink jet recording method for printing a pigment according to claim 1 , wherein the amount of the ink of the ink droplet is 5.9 ng, and the average discharging speed V is in the range of 5 m/s to 15 m/s.

4. The ink jet recording method for printing a pigment according to claim 1 , wherein the solid content of the pigment printing ink composition is 8% by mass or greater.

5. The ink jet recording method for printing a pigment according to claim 1 , wherein the pigment printing ink composition includes a pigment, and a resin dispersion.

6. The ink jet recording method for printing a pigment according to claim 1 , wherein the cloth includes cotton or a cotton blend.

7. The ink jet recording method for printing a pigment according to claim 1 , further comprising adhering the pigment printing ink composition to the cloth, wherein the cloth to which the pigment printing ink composition is adhered is heat-treated.

8. The ink jet recording method for printing a pigment according to claim 7 , wherein further comprising using a heating temperature is 150° C. or higher in the heat treatment.

9. The ink jet recording method for printing a pigment according to claim 1 , wherein the amount of the pigment printing ink composition adhering to the cloth is in the range of 10 mg/inch 2 to 70 mg/inch 2 .

10. The ink jet recording method for printing a pigment according to claim 1 , wherein a dot formation density of the pigment printing ink composition on the cloth is 720 dpi or greater×720 dpi or greater.

11. The ink jet recording method for printing a pigment according to claim 1 , wherein the pigment printing ink composition is any one of a color ink including at least color pigment as a pigment and a black ink including at least carbon black pigment as a pigment.

12. An ink jet recording apparatus, wherein recording is performed by the ink jet recording method for printing a pigment according to claim 1 .

13. The ink jet recording method for printing a pigment according to claim 1 , wherein a content of the pigment is from 0.5 to 15% by mass with respect to the total mass of the ink composition.

14. The ink jet recording method for printing a pigment according to claim 5 , wherein the pigment printing ink composition includes a resin dispersion in which the resin is dispersed in a dispersion medium as fine particles, and a content of resin of the resin dispersion is from 3 to 15% by mass with respect to the total mass of ink composition.

15. The ink jet recording method for printing a pigment according to claim 1 , wherein the pigment printing composition comprises a water soluble organic solvent.

16. The ink jet recording method for printing a pigment according to claim 1 , wherein a solid content of the pigment printing ink composition is from 8 to 20% by mass with respect to the total mass of ink composition.

17. The ink jet recording method for printing a pigment according to claim 1 , wherein the content of the resin of the resin emulsion is 5% by mass or greater with respect to the total mass of the ink composition.

18. The ink jet recording method for printing a pigment according to claim 1 , wherein the ink composition comprises a moisturizing agent having a high boiling point of 200° C. or higher.

19. The ink jet recording method for printing a pigment according to claim 1 , wherein further comprising adhering the pigment printing ink composition to the cloth, wherein the cloth to which the pigment printing ink composition is adhered is heat-treated by a heat press.

20. The ink jet recording method for printing a pigment according to claim 1 , wherein the amount of the ink of the ink droplet is 13 ng or less.

21. The ink jet recording method for printing a pigment according to claim 1 , wherein the amount of the ink of the ink droplet is 9 ng or less.

22. The ink jet recording method for printing a pigment according to claim 1 , wherein the content of the water in 20% by mass or more with respect to a total mass of the ink compositions.
