Abstract

The invention relates to a printing ink system containing glycosidic polymers and polyolefin- and/or Fischer-Tropsch-waxes and/or amide waxes and/or bio-based waxes and optionally pigments, binders and/or solvents. The glycosidic polymer has a specific surface area according to BET from a minimum 0.45 m2/g and a particle size distribution having an uniformity coefficient (D60/D10) to a maximum of 3.5.

First claim

The invention claimed is:

1. A printing ink comprising a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein the wax is used in micronized form with a d99 value of at most 100 μm.

2. The printing ink as claimed in claim 1 , wherein non-modified polyglycosides are used as the glycosidic polymer.

3. A printing ink comprising a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein modified polyglycosides are used as the glycosidic polymer.

4. The printing ink as claimed in claim 1 , wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.1 to 12.0% by weight.

5. The printing ink as claimed in claim 1 , wherein the wax is used in an amount, based on the printing ink, of from 0.1 to 12.0% by weight.

6. A method for improving the settling and redispersion behavior and the rub fastness of a printing ink comprising the step of applying a printing ink-to a substrate, wherein the printing ink comprises a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein the wax is used in micronized form with a d99 value of at most 100 μm.

7. The method as claimed in claim 6 , wherein non-modified polyglycosides are used as the glycosidic polymer.

8. The method as claimed in claim 6 , wherein modified polyglycosides are used as the glycosidic polymer.

9. The method as claimed in claim 6 , wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.1 to 12.0% by weight.

10. The method as claimed in claim 6 , wherein the wax is used in an amount, based on the printing ink, of from 0.1 to 12.0% by weight.

11. The method as claimed in claim 6 , wherein the glycosidic polymer and wax are comminuted by micronization or sifting to a specific surface area, measured in accordance with BET, of at least 0.80 m 2 /g and a non-uniformity number of less than 3.5.

12. The method as claimed in claim 6 , wherein the glycosidic polymer and the wax are micronized together and are used as a micronized mixture.

13. The printing ink as claimed in claim 1 , wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.1 to 6.0% by weight.

14. A printing ink comprising a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.2 to 2.0% by weight.

15. The printing ink as claimed in claim 1 , wherein the wax is used in an amount, based on the printing ink, of from 0.1 to 6.0% by weight.

16. The printing ink as claimed in claim 1 , wherein the wax is used in an amount, based on the printing ink, of from 0.2 to 2.0% by weight.

17. A printing ink comprising a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein the wax is used in micronized form with a d99 value of at most 30 μm.

18. A printing ink comprising a glycosidic polymer and a wax selected from the group consisting of polyolefin waxes, Fischer-Tropsch waxes, amide waxes and bio-based waxes and solvents,
where the glycosidic polymer has a specific surface area according to BET of minimally 0.45 m 2 /g and a particle size distribution with a non-uniformity number (D60/D10) up to at most 3.5, and wherein the wax is used in micronized form with a d99 value of at most 20 μm.

19. The method as claimed in claim 6 , wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.1 to 6.0% by weight.

20. The method as claimed in claim 6 , wherein the glycosidic polymer is used in an amount, based on the printing ink, of from 0.2 to 2.0% by weight.

21. The method as claimed in claim 6 , wherein the wax is used in an amount, based on the printing ink, of from 0.1 to 6.0% by weight.

22. The method as claimed in claim 6 , wherein the wax is used in an amount, based on the printing ink, of from 0.2 to 2.0% by weight.
