Abstract

A non-provisioned card having a front side and a back side, and at least one visible surface that is patinated or activated to promote patination.

First claim

What is claimed:

1. A process for making a transaction card having first and second visible surfaces including a first area and at least one of the first and second visible surfaces including a second area separate from the first area, the method comprising:
treating at least the first area with a first patina-retarding or patina-preventing surface treatment, coating or layer, such that a degree of patina retardation or prevention of the first area is greater than a degree of patina retardation or prevention of the second area not so treated; and
after treating at least the first area, providing the card for provisioning and issuance to a card holder.

2. The process of claim 1 , wherein the first area comprises a patinated surface having a desired degree of perceptible patination, wherein the first area resides on a metal substrate and the step of treating the first area comprises, prior to treating at least the first area with the first patina-retarding or patina-preventing surface treatment, coating or layer, first chemically patinating the metal substrate through an acid activation in the presence of a reductant, then exposing the patinated metal surface to an alkaline solution.

3. The process of claim 2 , wherein the alkaline solution comprises a bicarbonate salt solution.

4. The process of claim 1 , wherein the first surface resides on a metal substrate and the step of treating the surface comprises a flame treatment.

5. The process of claim 1 , wherein the first surface resides on a metal substrate and the step of treating the surface comprises an electrolytic treatment.

6. The process of claim 1 , wherein the first surface resides on a metal substrate and the step of treating to promote patination comprises activating a surface of a metal face of the metal substrate by mechanically removing any oxide from the surface.

7. The process of claim 6 , wherein the step of mechanically removing the oxide comprises wet or dry blasting.

8. The process of claim 1 , wherein the patinated or patina-ready surface resides on a substrate from the group consisting of: stone, wood, metal and leather.

9. The process of claim 1 , wherein the first area resides on a substrate comprising a metal selected from the group consisting of: copper, bronze, brass, silver, and alloys containing one or more the foregoing.

10. The process of claim 1 , wherein the first area resides on a decorative layer of a multi-layer card.

11. The process of claim 10 , wherein the card comprises a core with the decorative layer affixed to the core.

12. The process of claim 11 , wherein the core is non-metal and the decorative layer comprises metal.

13. The process of claim 11 , wherein the core comprises a first metal and the decorative layer comprises a second metal.

14. The process of claim 13 , wherein the decorative layer comprises copper and the core comprises stainless steel.

15. The process of claim 14 , wherein the card comprises a 0.002 inch layer of copper rolled onto a 0.018 inch layer of stainless steel.

16. The process of claim 10 , wherein the decorative layer comprises a metal foil laminated to a core.

17. The process of claim 16 , wherein the metal foil comprises copper and the core comprises stainless steel.

18. The process of claim 17 , wherein the foil has a thickness in the range of 0.003 inches to 0.005 inches.

19. The process of claim 10 , wherein the decorative layer is on a front of the card and the card further comprises a plastic layer on the back of the card.

20. The process of claim 1 , wherein the first area is provided on the first visible surface, and the second area is provided on the second visible surface.

21. The process of claim 1 , wherein the first area is disposed on a front of the card.

22. The process of claim 1 , wherein the first area comprises a first patinated surface disposed on a front side of the card and the second area comprises a second patinated surface disposed on a back side of the card.

23. The process of claim 22 , wherein the first area resides on a first copper layer and the second area resides on a second copper layer.

24. The process of claim 23 , wherein the card is a multi-layer card having a stainless steel core disposed between the first copper layer and the second copper layer.

25. The process of claim 1 , further comprising a treating the second area with a second patina-retarding or patina-preventing, surface treatment, coating or layer.

26. The process of claim 25 , wherein the second patina-retarding or patina-preventing surface treatment, coating or layer is disposed over an entirety of the second area.

27. The process of claim 26 , wherein the first area and the second area each comprise a same material, and the first patina-retarding or patina-preventing surface treatment, coating or layer provides a different rate of patina retardation or prevention than that of the second patina-retarding or patina-preventing surface treatment, coating or layer.

28. The process of claim 1 , further comprising indicia that is decorative, informational, or a combination thereof, disposed on or over the first area.

29. The process of claim 1 , wherein the first and second areas are both provided on the first visible surface of the card, the second area comprises an area containing card indicia selected from the group consisting of the card number and the cardholder name, and the first area comprises an area not containing the card indicia.

30. A process for making a transaction card having first and second visible surfaces including a first area and at least one of the first and second visible surfaces including a second area separate from the first area, the method comprising:
treating at least the first area with a first patina-accelerating surface treatment, coating or layer, such that a rate of accelerated patination of the first area is greater than a rate of patination of the second area; and
after treating at least the first area, providing the card for provisioning and issuance to a card holder.

31. The process of claim 30 , wherein the first area resides on a substrate comprising a metal selected from the group consisting of: copper, bronze, brass, silver, and alloys containing one or more the foregoing.

32. The process of claim 30 , wherein the first area resides on a decorative layer of a multi-layer card.

33. The process of claim 32 , wherein the card comprises a core with the decorative layer affixed to the core.

34. The process of claim 33 , wherein the core comprises a first metal and the decorative layer comprises a second metal.

35. The process of claim 34 , wherein the decorative layer comprises copper and the core comprises stainless steel.

36. The process of claim 35 , wherein the card comprises a 0.002 inch layer of copper rolled onto a 0.018 inch layer of stainless steel.

37. The process of claim 32 , wherein the decorative layer comprises a metal foil laminated to a core.

38. The process of claim 37 , wherein the metal foil comprises copper and the core comprises stainless steel.

39. The process of claim 38 , wherein the foil has a thickness in the range of 0.003 inches to 0.005 inches.
