Abstract

An ink composition of inkjet recording which includes at least one surfactant containing benzophenone polyoxyethylene glycol-based compound, a colorant, and a solvent. A multi-color ink set that includes the ink composition of inkjet recording, a cartridge of inkjet recording, and an inkjet recording apparatus are also provided.

Claims

1. An ink composition of inkjet recording, the ink composition comprising:

at least one surfactant containing benzophenone polyoxyethylene glycol-based compound as illustrated in Chemical Formula 1 below;

a colorant; and

a solvent.

2. The ink composition of claim 1, wherein a content of benzophenon polyoxyethylene glycol-based compound is about 0.1 to about 20 parts by weight, a content of the colorant is about 0.1 to about 15 parts by weight, and a content of the solvent is about 70 to about 90 parts by weight respectively based on 100 parts by weight of a total weight of the ink composition.

3. The ink composition of claim 1, wherein the surfactant further comprises at least one compound selected from the group consisting of compounds represented by Chemical Formula 2 through 5 illustrated below in a content of about 0.1 to about 15 parts by weight based on 100 parts by weight of a total weight of the ink composition.

4. The ink composition of claim 3, wherein the surfactant further comprises the compound of Chemical Formula 4.

5. The ink composition of claim 1, wherein the ink composition has a viscosity of about 1.5 to about 20 cps.

6. The ink composition of claim 1, wherein the ink composition has a dynamic surface tension of about 20 to about 40 dyne/cm at 0 Hz, and a dynamic surface tension difference between a dynamic surface tension at 15 Hz and that of at 0 Hz is 0 to about 30 dyne/cm.

7. The ink composition of claim 1, wherein the colorant is a dye, a pigment, or a self-dispersing type pigment.

8. The ink composition of claim 1, wherein the solvent is water, a water miscible organic solvent, or a mixture of these solvents.

9. The ink composition of claim 8, wherein the water miscible solvent is at least one selected from the group consisting of a monohydric alcohol solvent, a ketone solvent, an ester solvent, a polyhydric solvent, a polyhydric alcohol derivative solvent, a nitrogen-containing solvent, and a sulfur-containing solvent.

10. The ink composition of claim 8, wherein the content of the water-miscible solvent is about 0.1 to about 130 parts by weight based on 100 parts by weight of water.

11. A multi-color ink set having an ink composition of inkjet recording, wherein the ink composition comprises at least one surfactant containing benzophenone polyoxyethlene glycol-based compound as illustrated in Chemical Formula 1 below;

a colorant; and

a solvent,

12. The multi-color ink set of claim 11, wherein a content of benzophenon polyoxyethylene glycol-based compound is about 0.1 to about 20 parts by weight, a content of the colorant is about 0.1 to about 15 parts by weight, and a content of the solvent is about 70 to about 90 parts by weight respectively based on 100 parts by weight of a total weight of the ink composition.

13. The multi-color ink set of claim 11, wherein the surfactant further comprises at least one compound selected from the group consisting of compounds represented by Chemical Formula 2 through 5 illustrated below in a content of about 0.1 to about 15 parts by weight based on 100 parts by weight of a total weight of the ink composition.

14. The multi-color ink set of claim 13, wherein the surfactant further comprises the compound of Chemical Formula 4.

15. The multi-color ink set of claim 11, wherein the ink composition has a viscosity of about 1.5 to about 20 cps.

16. The multi-color ink set of claim 11, wherein the ink composition has a dynamic surface tension of about 20 to about 40 dyne/cm at 0 Hz, and a dynamic surface tension difference between a dynamic surface tension at 15 Hz and that of at 0 Hz is 0 to about 30 dyne/cm.

17. The multi-color ink set of claim 11, wherein the colorant is a dye, a pigment, or a self-dispersing type pigment.

18. The multi-color ink set of claim 11, wherein the solvent is water, a water miscible organic solvent, or a mixture of these solvents.

19. A cartridge of inkjet recording, the cartridge comprises the multi-color ink set according to claim 11.

20. An inkjet recording apparatus having the cartridge of inkjet recording according to claim 12.
