Abstract

An image-bearing article comprising a rigid sheet bearing an image which is coated on the image-bearing side and over the image with an adhesion promoter.

A process of preparing an image-bearing article comprising a coated image-bearing rigid sheet:

• • (a) providing a rigid sheet;
  • (b) printing an image on the rigid sheet so as to produce an image-bearing rigid sheet containing an image-bearing side; and
  • (c) coating an adhesion promoter on the image-bearing side and over the image to produce a coated image-bearing rigid sheet containing a coated image-bearing side.

Claims

1. An image-bearing article comprising a rigid sheet bearing an image which is coated on the image-bearing side and over the image with an adhesion promoter.

2. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of silane and poly(alkyl amine) adhesion promoters, and mixtures thereof.

3. The image-bearing article of claim 1 wherein the adhesion promoter is an aminosilane.

4. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of poly(vinyl amine), poly(allyl amine) and mixtures thereof.

5. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of vinyltriethoxysilane, vinyltrimethoxysilane, vinyltris(beta-methoxyethoxy)silane, gamma-methacryloxypropyltrimethoxysilane, beta-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, gamma-glycidoxypropyltrimethoxysilane, gamma-glycidoxypropylmethyldiethoxysilane, vinyl-triacetoxysilane, gamma-mercaptopropyltrimethoxysilane, (3-aminopropyl)trimethoxysilane, (3-minopropyl)triethoxysilane, N-beta-(aminoethyl)-gamma-aminopropyl-trimethoxysilane, N-(beta-aminoethyl)gamma-aminopropylmethyldimethoxysilane, aminoethylaminopropyl silane triol homopolymer, vinylbenzylaminoethylaminopropyltrimethoxysilane, bis(trimethoxysilylpropyl)amine, and mixtures thereof.

6. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of (3-minopropyl)trimethoxysilane, (3-aminopropyl)triethoxysilane, N-beta-(aminoethyl)-gamma-aminopropyl-trimethoxysilane, N-(beta-aminoethyl) gamma-aminopropylmethyldimethoxysilane, aminoethylaminopropyl silane triol homopolymer, vinylbenzylaminoethylaminopropyltrimethoxysilane, bis(trimethoxysilylpropyl)amine, and mixtures thereof.

7. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of gamma-aminopropyltriethoxysilane, and N-beta-(aminoethyl)-gamma-aminopropyl-trimethoxysilane and mixtures thereof.

8. The image-bearing article of claim 1 wherein the rigid sheet is selected from the group consisting of glass, poly(carbonate), and poly(methacrylate) sheets.

9. The image-bearing article adhesion coating of claim 1 with a thickness of less than 1 mil.

10. The image-bearing article of claim 1 wherein the rigid sheet is a glass sheet.

11. The image-bearing article of claim 1 wherein the image comprises UV-curable ink.

12. The image-bearing article of claim 1 wherein the image comprises pigment ink.

13. The image-bearing article of claim 12 wherein the image is formed from solvent-based ink.

14. The image-bearing article of claim 1 further comprising a polymeric interlayer sheet selected from the group consisting of poly(vinyl acetal) sheets and poly(ethylene-co-vinyl acetate) sheets laminated to the image-bearing rigid sheet by the adhesion promoter.

15. The image-bearing article of claim 14 wherein the polymeric interlayer sheet is a poly(vinyl butyral) sheet.

16. The image-bearing article of claim 14 wherein the polymeric interlayer sheet is an ethylene vinyl acetate sheet.

17. The image-bearing article of claim 14 with a laminate adhesive strength of about 1000 psi or greater.

18. The image-bearing article of claim 14 further comprising a second rigid sheet laminated to the interlayer sheet.

19. An image-bearing article comprising:

(a) a first rigid sheet bearing an image which is coated on the image-bearing side and over the image with an adhesion promoter selected from the group consisting of aminosilane, poly(vinyl amine), poly(allyl amine) and mixtures thereof, wherein the rigid sheet is selected from the group consisting of glass, poly(carbonate), and poly(methacrylate) sheets;

(b) a polymeric interlayer sheet selected from the group consisting of poly(vinyl acetal) sheets and poly(ethylene-co-vinyl acetate) sheets laminated to the image-bearing rigid sheet by the adhesion promoter; and

(c) a second rigid sheet laminated to the interlayer sheet, wherein the second rigid sheet is selected from the group consisting of glass, poly(carbonate), and poly(methacrylate) sheets.

20. The image-bearing article of claim 19 wherein the wherein the first and second rigid sheet are glass sheets and the polymeric interlayer sheet is a poly(vinyl butyral sheet).

21. A process of preparing an image-bearing article comprising a coated image-bearing rigid sheet:

(a) providing a rigid sheet;

(b) printing an image on the rigid sheet so as to produce an image-bearing rigid sheet containing an image-bearing side; and

(c) coating an adhesion promoter on the image-bearing side and over the image to produce a coated image-bearing rigid sheet containing a coated image-bearing side.

22. The process of claim 21 further comprising laminating an interlayer sheet to the coated image-bearing side of the coated image-bearing rigid sheet.

23. The process of claim 22 further comprising laminating a second rigid sheet to the interlayer sheet, wherein the rigid sheet and second rigid sheet are each selected from the group consisting of glass, poly(carbonate), and poly(methacrylate) sheets.

24. The process of claim 22 wherein (a) the rigid sheet is a glass sheet, (b) the second rigid sheet is selected from the group consisting of glass, poly(carbonate) and poly(methacrylate) sheets, (c) the interlayer sheet is a poly(vinyl butyral) sheet or an ethylene vinyl acetate sheet, (d) the printing comprises ink jet printing, (e) the laminating includes applying heat and, optionally, pressure, and (f) the adhesion promoter is selected from the group consisting of aminosilane, poly(vinyl amine), poly(allyl amine) and mixtures thereof.
