Abstract

An image-bearing article comprising a film layer bearing an image which is coated on the image-bearing side and over the image with an adhesion promoter and which is adhered by the adhesion promoter to a polymeric interlayer.

A process of preparing an image-bearing article comprising a coated image-bearing film layer:

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

Claims

1. An image-bearing article comprising a film layer bearing an image which is coated on the image-bearing side and over the image with an adhesion promoter and which is adhered by the adhesion promoter to a polymeric interlayer.

2. The image-bearing article of claim 1 wherein the polymeric interlayer is a poly(vinyl butyral) sheet.

3. The image-bearing article of claim 1 wherein the article further comprises a rigid sheet adhered to the polymeric interlayer.

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

5. The image-bearing article of claim 2 wherein the article further comprises a rigid sheet adhered to the polymeric interlayer.

6. The image-bearing article of claim 5 wherein the rigid sheet is a sheet of glass.

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

8. The image-bearing article of claim 6 wherein the adhesion promoter is selected from the group consisting of silanes and poly(alkyl amine) adhesion promoters, and mixtures thereof.

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

10. 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.

11. 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-aminopropyl)triethoxysilane, N-beta-(aminoethyl)-gamma-aminopropyl-trimethoxysilane, N-(beta-aminoethyl) gamma-aminopropylmethyldimethoxysilane, aminoethylaminopropyl silane triol homopolymer, vinylbenzylaminoethylaminopropyltrimethoxysilane, bis(trimethoxysilylpropyl)amine, and mixtures thereof.

12. The image-bearing article of claim 1 wherein the adhesion promoter is selected from the group consisting of (3-aminopropyl)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.

13. 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.

14. The image-bearing article of claim 1 wherein the film layer is a polyester film.

15. The image-bearing article of claim 1 wherein the film layer is a biaxially-oriented, poly(ethylene terephthalate) film.

16. The image-bearing article of claim 6 wherein the film layer is a biaxially-oriented, poly(ethylene terephthalate) film.

17. The image-bearing article of claim 1 wherein the film layer is a solar control film.

18. The image-bearing article of claim 1 wherein the adhesion coating has a thickness of less than 1 mil.

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

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

21. The image-bearing article of claim 1 with a laminate adhesive strength of about 1000 psi or greater.

22. The image-bearing article of claim 8 wherein the adhesion coating has a thickness of up to about 1 mil, the polymeric interlayer has a thickness of about 10 to about 250 mils, and the film has a thickness of about 0.1 mils to about 10 mils.

23. An image-bearing article comprising:

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

(b) a poly(vinyl butyral) interlayer sheet laminated to the image-bearing film layer by the adhesion promoter;

(c) a film layer 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;

(d) a second poly(vinyl butyral) interlayer sheet laminated to the film layer; and

(e) 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.

24. The image-bearing article of claim 23 wherein the wherein the first and second rigid sheet are glass sheets, the film layer is a solar control film and the polymeric interlayer sheet is a poly(vinyl butyral sheet).

25. A process of preparing an image-bearing article comprising a coated image-bearing film layer:
