Abstract

The present invention relates to a protective film for application to a card member and forming identification cards having protective films. The method of applying protection to a card member includes providing a protective film. The protective film includes a protective overlay and an ink-receptive material. The ink-receptive material includes an ink-receptive coating on a backing layer. The ink-receptive coating is bonded to the protective overlay. The method also includes removing the backing layer from the ink-receptive coating and laminating the ink-receptive coating to a surface of a card member.

Claims (55)

1. A method of forming an identification card comprising:

providing a protective film comprising:

a protective overlay;

an ink-receptive material having an ink-receptive coaxing on a backing layer, the ink-receptive coating bonded to the protective overlay;

removing the backing layer from the ink-receptive coating;

laminating the protective film to a surface of a card member; and

removing a portion of the ink-receptive coating that is not laminated to the surface of the card member.

2. The method of claim 1 and further comprising printing an image to the ink-receptive coating prior to bonding the ink-receptive coating to the protective overlay.

3. The method of claim 1 and further comprising printing an image to the ink-receptive coating prior to laminating the protective film to the surface of the card member.

4. The method of claim 1 and further comprising printing an image to the surface of the card member prior to laminating the protective film to the surface of the card member.

5. The method of claim 1 , wherein the providing step comprises providing the ink-receptive coating having an inorganic material and an organic material.

6. The method of claim 5 , wherein the inorganic material comprises a boehmite form of alumina hydrate.

7. The method of claim 5 , wherein the organic material comprises one of a starch and a polyvinyl alcohol.

8. The method of claim 5 , wherein the organic material comprises an organic material that acts as a binder.

9. The method of claim 8 , wherein organic material comprises one of a styrene-butadiene copolymer rubber latex, carboxymethyl cellulose, hydroxymethyl cellulose and polyvinyl pyrrolidone.

10. The method of claim 8 , wherein the organic material comprises one of dithiocarbamates, thiurams, thiocyanate esters, thiocyanates and hindered amines.

11. The method of claim 1 , wherein the ink-receptive coating comprises providing a polymerizable binder.

12. The method of claim 1 , wherein the ink-receptive coating comprises magnesium and thiocyanate ions.

13. The method of claim 1 , wherein the backing layer comprises one of polyethylene terephthalate (PET), polyester diacetate, polycarbonate resins, fluororesins, and polyvinyl chloride resins.

14. The method of claim 1 and further comprising applying an anti-static coating to the card member.

15. A method of forming a protective film comprising:

providing a protective overlay;

providing an ink-receptive material having an ink-receptive coating removably attached to a surface of a backing layer;

bonding the ink-receptive material to the protective overlay such that the ink-receptive coating is in contact with the protective overlay; and

removing the backing layer and a portion of the ink-receptive coating that is not bonded to the protective overlay, the portion of the ink-receptive coating that is not bonded to the protective overlay remains with the backing layer.

16. The method of claim 15 , wherein the protective overlay comprises a transfer film layer.

17. The method of claim 16 , wherein the protective overlay further comprises a carrier layer, the transfer film layer removably attached to the carrier layer.

18. The method of claim 17 , wherein the carrier layer comprises polyester.

19. The method of claim 16 , wherein the ink receptive coating is bonded to the transfer film layer with an adhesive.

20. The method of claim 19 , wherein the transfer film layer and the adhesive comprises a thickness of 3–6 microns.

21. The method of claim 16 , wherein the transfer film layer comprises a security image.

22. The method of claim 21 , wherein the security image comprises a hologram.

23. The method of claim 16 , wherein the transfer film layer comprises an acrylate polymer such as polymethyl methacrylate.

24. The method of claim 15 , wherein the protective overlay comprises one of a clear polyvinyl chloride film and a clear polyvinyl acetate film.

25. The method of claim 24 , wherein the protective overlay comprises a thickness of 1–5 mils.

26. The method of claim 15 , wherein the ink-receptive coating is imaged with a printer.

27. A method of forming an identification card, the method comprising:

(a) providing a protective overlay;

(b) providing an ink-receptive material having an ink-receptive coating removably attached to a backing layer;

(c) bonding the ink-receptive material to a surface of the protective overlay with the ink-receptive coating in contact with the surface of the protective overlay to thereby form a protective film;

(d) removing the backing layer from the protective film;

(e) laminating the protective film to a surface of a card member, wherein the ink-receptive coating is in contact with the surface of the card member; and

(f) removing a portion of the ink-receptive coating that is not laminated to the surface of the card member.

28. The method of claim 27 , wherein the protective overlay comprises a transfer film layer.

29. The method of claim 28 , wherein the protective overlay comprises a carrier layer removably attached to the transfer film layer.

30. The method of claim 29 and further comprising removing the carrier layer from the protective film.

31. The method of claim 27 , wherein the protective overlay comprises one of a clear polyvinyl chloride film and a clear polyvinyl acetate film.

32. The method of claim 27 and further comprising printing an image on a surface of the ink-receptive coating before step (e).

33. The method of claim 32 , wherein the printing step comprises printing a reverse image on the surface of the ink-receptive coating.

34. The method of claim 27 and further comprising printing an image on a surface of the ink-receptive coating before step (c).

35. The method of claim 27 and further comprising applying an anti-static coating to a surface of the card member prior to laminating step (e).

36. The method of claim 35 , wherein the anti-static coating comprises dimethyl ditallow ammonium chloride.

37. The method of claim 35 , wherein the anti-static coating comprises a second ink-receptive coating.

38. The method of claim 35 , wherein the anti-static layer comprises an overlay film having an anti-static coating.

39. The method of claim 27 and further comprising printing an image on the surface of the card member prior to step (e).
