Claims

What is claimed is:

1. An ink composition comprising:

a white pigment material;

a resin composition comprising:

a silicone resin component; and

at least one of an amino resin component or an acrylic resin component; and

a solvent composition comprising one or more of a propylene-glycol-ether, diethylene-glycol-dimethyl-ether, propylene-glycol-methyl-ether-acetate, or diethylene-glycol-diethyl ether.

2. The ink composition of claim 1, wherein the ink composition is inkjet printable and thermally curable.

3. The ink composition of claim 1 or 2, wherein the white pigment material comprises a titanium dioxide powder having an average particle size D50 in a range from 100 nm to 250 nm.

4. The ink composition of claim 3, wherein the average particle size D50 is in a range from 150 nm to 250 nm.

5. The ink composition of any preceding claim, wherein the silicone resin component comprises a silsesquioxane.

6. The ink composition of claim 5, wherein the silsesquioxane is divinyl-hexamethyl-octasila-silsesquioxane.

7. The ink composition of any preceding claim, wherein the solvent composition comprises two or more of a propylene-glycol-ether, diethylene-glycol-dimethyl-ether, propylene-glycol-methyl-ether-acetate, or diethylene-glycol-diethyl ether.

8. The ink composition of any preceding claim, wherein the solvent composition comprises three or more of a propylene-glycol-ether, diethylene-glycol-dimethyl-ether, propylene-glycol-methyl-ether-acetate, or diethylene-glycol-diethyl ether.

9. The ink composition of any preceding claim, wherein the solvent composition comprises propylene-glycol-ether, diethylene-glycol-dimethyl-ether, propylene-glycol- methyl-ether-acetate, and diethylene-glycol-diethyl ether.

10. The ink composition of any preceding claim, wherein the propylene-glycol-ether is propylene-glycol-monomethyl-ether.

11. The ink composition of any preceding claim, further comprising:

a dispersant; and

a flow promoter.

12. The ink composition of claim 11, wherein the flow promoter comprises modified polyether polydimethylsiloxane.

13. The ink composition of any preceding claim, wherein the resin composition comprises an amino resin component and an acrylic resin component.

14. The ink composition of any preceding claim, wherein the resin composition further comprises an epoxy resin component.

15. The ink composition of any preceding claim, comprising:

the pigment material in a range from 9 to 14 weight percent;

the silicone resin component in a range from 12 to 25 weight percent;

the amino resin component in a range from 0 to 10 weight percent; the acrylic resin component in a range from 0 to 10 weight percent; the propylene-glycol-ether in a range from 15 to 25 weight percent; diethylene-gly col-dimethyl-ether in a range from 10 to 20 weight percent;

diethylene-glycol-diethyl ether in a range from 0 to 10 weight percent; and propylene-glycol- methyl-ether-acetate in a range from 13 to 25 weight percent.

16. The ink composition of claim 15 further comprising:

a dispersant in a range from 1 to 4 weight percent;

a flow promoter in a range from 0.5 to 3.5 weight percent; and

an epoxy resin component in a range from 0 to 10 weight percent.

17. An ink coating method comprising the steps of:

coating upon a substrate an uncured inkjet ink composition of any preceding claim; and

curing in-situ the uncured inkjet ink composition to form a cured ink composition upon the substrate.

18. The method of claim 17, wherein the substrate is selected from the group consisting of a glass substrate, a glass-ceramic substrate, a ceramic substrate, a metal oxide substrate, a metal substrate, and a polymeric substrate.

19. The method of claim 17 or 18, wherein the uncured inkjet ink composition is thermally cured to form the cured ink composition.

20. The method of any one of claims 17-19, wherein the cured ink composition has an optical density in a range from greater than 0.2 to 1.0.

21. The method of claim 20, wherein the cured ink composition has an optical density in a range from greater than 0.5 to 1.0.

22. A coated article, the coated article comprising:

a substrate; and

a cured coating located upon the substrate, the cured coating comprising the ink composition of any one of claims 1-16.

23. The coated article of claim 22, wherein the cured coating has a thickness in a range from 1 micron to 10 microns.

24. The coated article of claim 22 or 23, wherein the cured coating has an optical density in a range from greater than 0.2 to 1.0.

25. The coated article of claim 24, wherein the cured coating has an optical density in a range from greater than 0.5 to 1.0.

26. The coated article of any one of claims 22-25, wherein the adhesion of the cured coating to the substrate is greater than or equal to 4B according to a cross hatch adhesion test set forth in ASTM D3359-09e2.

27. An electronic device comprising the coated article of any one of claims 22-26.
