Abstract

A pretreatment liquid for an oil-based ink contains one of a maleic anhydride resin derivative and an aluminum chelate compound.

First claim

What is claimed is:

1. A pretreatment liquid for an oil-based ink, the pretreatment liquid comprising one of a maleic anhydride resin derivative and an aluminum chelate compound,
wherein the aluminum chelate compound is represented by one of the following formulas (1) and (2):

wherein R 1 O represents a volatile alkoxy group, R 2 , R 3 , and R 4 each represent an alkyl group, and R 5 represents a methyl group or R 1 O; and

wherein R 6 O represents a volatile alkoxy group, and R 7 represents an alkyl group.

2. The pretreatment liquid according to claim 1 , wherein the oil-based ink contains an organic solvent being at least one selected from the group consisting of alcohols, primary amines, and secondary amines, and wherein the pretreatment liquid contains a maleic anhydride resin derivative.

3. The pretreatment liquid according to claim 2 , wherein the organic solvent has a carbon number of 12 or more.

4. An oil-based ink jet printing ink set comprising the pretreatment liquid as set forth in claim 3 .

5. An oil-based ink jet printing method comprising printing with the oil-based ink jet printing ink set as set forth in claim 4 .

6. An oil-based ink jet printing ink set comprising the pretreatment liquid as set forth in claim 2 .

7. An oil-based ink jet printing method comprising printing with the oil-based ink jet printing ink set as set forth in claim 6 .

8. The pretreatment liquid according to claim 1 , wherein the maleic anhydride resin derivative is at least one selected from the group consisting of rosin-modified maleic anhydride resins, acrylic-modified maleic anhydride resins, and styrene-modified maleic anhydride resins.

9. An oil-based ink jet printing ink set comprising the pretreatment liquid as set forth in claim 8 .

10. An oil-based ink jet printing method comprising printing with the oil-based ink jet printing ink set as set forth in claim 9 .

11. The pretreatment liquid according to claim 1 , wherein the oil-based ink contains an organic solvent that is a higher alcohol having a carbon number of 12 or more.

12. An oil-based ink jet printing ink set comprising the pretreatment liquid as set forth in claim 11 .

13. An oil-based ink jet printing method comprising printing with the oil-based ink jet printing ink set as set forth in claim 12 .

14. An oil-based ink jet printing ink set comprising the pretreatment liquid as set forth in claim 1 .

15. An oil-based ink jet printing method comprising printing with the oil-based ink jet printing ink set as set forth in claim 14 .

16. An oil-based ink jet printing ink set comprising:
an oil-based ink; and
a pretreatment liquid comprising one of a maleic anhydride resin derivative and an aluminum chelate compound.

17. The oil-based ink jet printing ink set according to claim 16 , wherein the oil-based ink contains an organic solvent being at least one selected from the group consisting of alcohols, primary amines, and secondary amines, and wherein the pretreatment liquid contains a maleic anhydride resin derivative.

18. The oil-based ink jet printing ink set according to claim 16 , wherein the maleic anhydride resin derivative is at least one selected from the group consisting of rosin-modified maleic anhydride resins, acrylic-modified maleic anhydride resins, and styrene-modified maleic anhydride resins.

19. The oil-based ink jet printing ink set according to claim 17 , wherein the organic solvent has a carbon number of 12 or more.

20. The oil-based ink jet printing ink set according to claim 16 , wherein the aluminum chelate compound is represented by one of the following formulas (1) and (2):

wherein R 1 O represents a volatile alkoxy group, R 2 , R 3 , and R 4 each represent an alkyl group, and R 5 represents a methyl group or R 1 O; and

wherein R 6 O represents a volatile alkoxy group, and R 7 represents an alkyl group.

21. The oil-based ink jet printing ink set according to claim 16 , wherein the oil-based ink contains an organic solvent that is a higher alcohol having a carbon number of 12 or more.
