Abstract

A white ink composition contains a white pigment and fixing resins. The fixing resins include a vinyl chloride resin or a urethane resin, a fluorene resin, and a polyolefin wax.

First claim

What is claimed is:

1. A white ink jet ink water based composition comprising:
water,
a white pigment, wherein the content of white pigment is 1% to 20% by mass; and
fixing resins including a vinyl chloride resin, a fluorene resin, and a polyolefin wax,
wherein the vinyl chloride resin is resin particles dispersed in water, and
wherein the mass ratio of the vinyl chloride resin to the fluorene resin is 5:1 to 1:6 and the mass ratio of the polyolefin wax to the fluorene resin is 3:2 to 1:5.

2. The white ink jet ink water based composition according to claim 1 , wherein the vinyl chloride resin content is in the range of 0.5% to 10% by mass.

3. The white ink jet ink water based composition according to claim 1 , wherein the polyolefin wax has an average particle size in the range of 30 to 700 nm.

4. A recorded material comprising an image recorded with the white ink jet ink water based composition as set forth in claim 1 .

5. The white ink jet ink composition according to claim 1 , wherein the vinyl chloride has a minimum film forming temperature of 30° C. or more.

6. The white ink jet ink composition according to claim 1 , wherein the white pigment has an average particle size in the range of 200 to 400 nm.

7. The white ink jet ink composition according to claim 1 , wherein the polyolefin wax content is in the range of 1% to 3% by mass.

8. The white ink jet ink composition according to claim 1 , wherein the polyolefin wax is resin particles dispersed in water.

9. A white ink jet ink composition comprising:
a white pigment, wherein the content of white pigment is 1% to 20% by mass and the white pigment has an average particle size in the range of 200 to 400 nm;
water; and
fixing resins including a vinyl chloride resin, a fluorene resin, and a polyolefin wax,
wherein the mass ratio of the polyolefin wax to the fluorene resin is 3:2 to 1:5.

10. A recorded material comprising an image recorded with the white ink jet ink composition as set forth in claim 9 .

11. The white ink jet ink composition according to claim 9 , wherein the polyolefin wax content is in the range of 1% to 3% by mass.

12. The white ink jet ink composition according to claim 9 , wherein the polyolefin wax is resin particles dispersed in water.
