Abstract

The invention relates to aqueous binder-free pigment dispersions containing (A) at least one organic and/or inorganic pigment, (B) one or more dispersing agents and/or surfactants, (C) at least one base of formula (I), where R 1 is H, C 1 -C 4 -alkyl, CH 2 CH 2 OH or CH 2 CH(CH 3 )OH, (D) optionally, one or more polyalkylene glycols, (E) optionally, other additives commonly used for making aqueous pigment dispersions, and (F) water.

First claim

The invention claimed is:

1. An aqueous, water-thinnable or solvent borne varnish comprising at least one aqueous, binder-free pigment dispersion, wherein the at least one aqueous, binder-free pigment dispersion comprises
(A) at least one organic and/or inorganic pigment,
(B) one or more dispersants and/or surfactants,
(C) at least one compound of the formula (I)

in which R 1 is H, C 1 -C 4 -alkyl, CH 2 CH 2 OH or CH 2 CH(CH 3 )OH, and

(F) water.

2. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , in which R 1 is methyl or CH 2 CH 2 OH.

3. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , in which R 1 is methyl.

4. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , wherein the inorganic pigment is a metal oxide pigment.

5. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , comprising 5% to 80% by weight of component (A) based on the total weight of the pigment dispersion.

6. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , comprising 0.1% to 30% by weight of component (B) based on the total weight of the pigment dispersion.

7. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , comprising 0.1% to 10% by weight of component (C) based on the total weight of the pigment dispersion.

8. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , comprising one or more polyalkylene glycols as component (D) in an amount of 0.1% to 10% by weight, based on the total weight of the pigment dispersion.

9. The aqueous, water-thinnable or solvent borne varnish as claimed in claim 1 , comprising further additives customary for production of aqueous pigment dispersions as components (E) in an amount of 0% to 30% by weight, based on the total weight of the pigment dispersion.

10. An aqueous, water-thinnable or solvent borne paint comprising at least one aqueous, binder-free pigment dispersion, wherein the at least one aqueous, binder-free pigment dispersion comprises
(A) at least one organic and/or inorganic pigment,
(B) one or more dispersants and/or surfactants,
(C) at least one compound of the formula (I)

in which R 1 is H, C 1 -C 4 -alkyl, CH 2 CH 2 OH or CH 2 CH(CH 3 )OH, and

(F) water.

11. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , in which R 1 is methyl or CH 2 CH 2 OH.

12. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , in which R 1 is methyl.

13. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , wherein the inorganic pigment is a metal oxide pigment.

14. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , comprising 5% to 80% by weight of component (A) based on the total weight of the pigment dispersion.

15. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , comprising 0.1% to 30% by weight of component (B) based on the total weight of the pigment dispersion.

16. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , comprising 0.1% to 10% by weight of component (C) based on the total weight of the pigment dispersion.

17. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , comprising one or more polyalkylene glycols as component (D) in an amount of 0.1% to 10% by weight, based on the total weight of the pigment dispersion.

18. The aqueous, water-thinnable or solvent borne paint as claimed in claim 10 , comprising further additives customary for production of aqueous pigment dispersions as components (E) in an amount of 0% to 30% by weight, based on the total weight of the pigment dispersion.

19. An aqueous, water-thinnable or solvent borne ink comprising at least one aqueous, binder-free pigment dispersion, wherein the at least one aqueous, binder-free pigment dispersion comprises
(A) at least one organic and/or inorganic pigment,
(B) one or more dispersants and/or surfactants,
(C) at least one compound of the formula (I)

in which R 1 is H, C 1 -C 4 -alkyl, CH 2 CH 2 OH or CH 2 CH(CH 3 )OH, and

(F) water.

20. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , in which R 1 is methyl or CH 2 CH 2 OH.

21. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , in which R 1 is methyl.

22. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , wherein the inorganic pigment is a metal oxide pigment.

23. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , comprising 5% to 80% by weight of component (A) based on the total weight of the pigment dispersion.

24. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , comprising 0.1% to 30% by weight of component (B) based on the total weight of the pigment dispersion.

25. The aqueous, water-thinnable or solvent borne ink as claimed in claim 19 , comprising 0.1% to 10% by weight of component (C) based on the total weight of the pigment dispersion.
