Abstract

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material. The cards may be dual interface smart cards which can be read in a contactless manner and/or via contacts.

First claim

What is claimed is:

1. A method for making a card with a given appearance comprising the steps of:
(a) preparing a decorative metal layer by anodizing a metal layer, then coloring the anodized metal layer with a dye to give the anodized metal layer a given color, and then sealing the colorized decorative metal layer; and
(b) preparing a core metal layer for forming the body of said card, said core layer having first and second surfaces generally parallel to each other, and a core color that differs from the given color of the colorized decorative metal layer;
(c) after performing each of steps (a) and (b), attaching said decorative metal layer to the metal core layer by laminating the layers;
(d) forming a hard coat layer over said decorative metal layer having a color that is different than the core layer and the decorative metal layer;
(e) removing portions of the hard coat layer in a first area to expose the decorative metal layer; and
(f) removing portions of the hard coat layer and any intervening layers in a second area different from the first area to expose the core metal layer,
(g) electroplating a third area of the decorative metal layer different from the first area and the second area with an electroplating metal having an electroplating color that differs from the given color of the colorized decorative metal layer and the core color of the core metal layer;
such that after performing each of steps (e) through (g), the card has a face displaying the color of the hard coat layer in a fourth area, the core color of the core metal layer in the second area, the electroplating color of the electroplating in the third area, and the given color of the colorized decorative metal layer in the first area.

2. The method as claimed in claim 1 , wherein said decorative layer comprises anodized aluminum and further including applying a laser source to said decorative metal layer to modify the card's color, appearance, and texture.

3. The method as claimed in claim 2 further including a polymeric layer attached to the second surface of the core metal layer.

4. The method as claimed in claim 2 further comprising at least one additional layer having a color different from the color of the core metal layer and the decorative layer, the additional layer being a polymeric layer attached to the second surface of the core layer, and an integrated circuit module is located within said card for enabling at least one of: (a) wireless radio frequency (RF) transmission between the card and an external card reader; and (b) contact reading between the card and a contact reader.

5. The method of claim 4 , wherein each removing step comprises applying a laser source to the at least one additional layer.

6. The method as claimed in claim 1 , wherein said metal decorative layer comprises anodized aluminum, further including the step of applying a laser source to said hard coat layer and to said anodized aluminum layer for modifying at least one of the color and texture of the card.

7. The method as claimed in claim 1 wherein each removing step comprises applying a laser source to remove portions of the card.

8. The method as claimed in claim 1 wherein said step of attaching a decorative layer to said core metal layer includes the step of forming a pocket within a surface of said core metal layer and firmly attaching one of said decorative layers within said pocket.

9. The method as claimed in claim 8 wherein the depth of the pocket is made substantially equal to the thickness of the decorative layer.

10. The method claim as claimed in claim 1 , further including the steps of dying the anodized metal layer multiple colors.

11. The method as claimed in claim 1 further including the step of modifying the anodized layer by laser engraving.

12. The method as claimed in claim 1 wherein the anodized metal layer is selectively extended along the surface of the card: (a) the full length and width of the card, (b) as a patch, (c) as a stripe, or (d) as a decorative design.

13. The method as claimed in claim 1 further including the step of attaching a decorative layer to the second surface of the core metal layer.

14. The method as claimed in claim 13 wherein said decorative layer attached to the second surface of the core metal layer includes one of (a) an anodized metal layer, (b) a plant derived material veneer layer; (c) an animal derived material veneer layer; (d) an aggregate binder material veneer layer; (e) a ceramic layer; and (f) a layer of crystal fabric material.

15. The method of claim 1 , further comprising printing graphics on the colorized anodized metal of the decorative layer.

16. The method of claim 1 , comprising attaching the decorative metal layer to the first surface of the core metal layer.

17. The method of claim 16 , comprising attaching the decorative metal layer to the first surface of the core metal layer with a first adhesive layer.

18. The method of claim 1 , in which the card comprises a multi-colored anodized metal layer, the decorative metal layer comprises a top sub-layer of the multi-colored anodized metal layer.

19. A card having a front side and a back side, said card comprising:
a core metal layer forming the bulk of the card and having a predetermined color and said core metal layer having first and second surfaces extending generally parallel to each other,
a decorative layer disposed over said first surface of said core metal layer for providing at least one of color and texture to the card, said decorative layer comprising a colorized anodized metal layer having a given color different from the predetermined color of the core metal layer,
a hard coat layer attached to said decorative layer having a color that is different than the core metal layer and the decorative layer,
an opening formed through the hard coat layer for displaying the color of the decorative layer, and
a second opening different from the opening formed through the hard coat layer and any intervening layers for displaying the color of the core metal layer,
an area of the decorative metal layer different from the opening and the second opening for displaying an electroplating color different from the color of the decorative layer and the color of the core metal layer,
wherein the core metal layer and the decorative layer are laminated together, and the colors of the hard coat layer, the decorative layer, the electroplated area, and the core metal layer are visible from the front side of the card.

20. The card as claimed in claim 19 wherein said decorative layer comprises an anodized aluminum layer that is a product of a process comprising anodizing a metal layer, then coloring the anodized metal layer with a dye to give the anodized metal layer the given color, and then sealing the colorized anodized metal layer.

21. The card as claimed in claim 19 , further comprising at least one additional layer having a color different from the color of the core metal layer and the decorative layer, the additional layer being attached to the core metal layer and a pattern is formed within said hard coat layer and said anodized aluminum layer and said core metal layer producing a pattern which displays the colors of said hard coat layer, said anodized aluminum layer, said core metal layer and said additional layer.

22. The card as claimed in claim 21 , wherein said anodized metal layer comprises a multi-colored metal layer, the decorative layer comprises one sub-layer of the multi-colored metal la
