Abstract

There is provided a water-based ink for ink-jet recording, including: a pigment; water; and alkyl glucoside which has alkyl group having 6 or more carbon atoms.

Claims (33)

1. A water-based ink for ink-jet recording comprising:

a pigment;

water; and

alkyl glucoside which has alkyl group having 8 to 12 carbon atoms,

wherein the alkyl glucoside is contained in the water-based ink in an amount of not less than 0.7% by weight and not more than 5% by weight.

2. The water-based ink for ink-jet recording according to claim 1 , wherein the alkyl glucoside has alkyl group having 8 carbon atoms.

3. The water-based ink for ink-jet recording according to claim 1 , wherein the alkyl glucoside has alkyl group having 10 carbon atoms.

4. The water-based ink for ink-jet recording according to claim 1 , wherein the alkyl glucoside has alkyl group having 12 carbon atoms.

5. The water-based ink for ink-jet recording according to claim 1 , wherein the alkyl glucoside is selected from the group consisting of 2 ethylhexyl-β-D-glucoside, n-decyl-β-D-glucoside, n-dodecyl-β-D-glucoside, and a combination thereof.

6. The water-based ink for ink-jet recording according to claim 1 , wherein the alkyl glucoside has alkyl group having 8 or 10 carbon atoms.

7. The water-based ink for ink-jet recording according to claim 6 , wherein the alkyl glucoside is selected from the group consisting of 2-ethylhexyl-β-D-glucoside, n-octyl-β-D-glucoside, n-decyl-β-D-glucoside, and a combination thereof.

8. The water-based ink for ink-jet recording according to claim 1 , further comprising 1,2-alkanediol having 4 to 6 carbon atoms.

9. An ink cartridge containing the water-based ink for ink-jet recording as defined in claim 1 .

10. An ink-jet recording apparatus comprising:

the water-based ink for ink-jet recording as defined in claim 1 ;

an ink accommodating section in which the water-based ink is accommodated; and

an ink discharge mechanism which is configured to discharge the water-based ink accommodated in the ink accommodating section.

11. A water-based ink for ink-jet recording comprising:

a pigment;

water;

alkyl glucoside which has alkyl group having 6 or more carbon atoms; and

1,2-alkanediol having 4 to 6 carbon atoms.

12. The water-based ink for ink-jet recording according to claim 11 , wherein the alkyl glucoside has alkyl group having 8 to 12 carbon atoms.

13. The water-based ink for ink-jet recording according to claim 11 , wherein the alkyl glucoside is contained by 0.7% by weight to 10% by weight in the water-based ink.

14. The water-based ink for ink-jet recording according to claim 11 , wherein the 1,2-alkanediol is straight-chain alkanediol.

15. The water-based ink for ink-jet recording according to claim 14 , wherein the 1,2-alkanediol is selected from the group consisting of 1,2-butanediol, 1,2-pentanediol, 1,2-hexanediol, and a combination thereof.

16. The water-based ink for ink-jet recording according to claim 11 , wherein a weight ratio (X:Y) of the alkyl glucoside (X) to the 1,2-alkanediol (Y) in the water-based ink is (X:Y)=1:1.5 to 1:40.

17. The water-based ink for ink-jet recording according to claim 11 , further comprising glycerol, wherein a total amount of the 1,2-alkanediol and the glycerol in the water-based ink is 15% by weight to 35% by weight.

18. An ink cartridge containing the water-based ink for ink-jet recording as defined in claim 11 .

19. An ink-jet recording apparatus comprising:

the water-based ink for ink-jet recording as defined in claim 11 ;

an ink accommodating section in which the water-based ink is accommodated; and

an ink discharge mechanism which is configured to discharge the water-based ink accommodated in the ink accommodating section.
