Abstract

A laminated core stock sheet for use in a composite laminate assembly configured for being separated into plural individual cards is provided. The laminated core stock sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes plural conductive bodies spaced apart from each other that provide at least one of a security feature, a decorative feature, or other functional feature of the individual cards. The core substrate layer and the intermediate filmic layer are configured to be coupled with another laminated core stock sheet that may or may not include the intermediate filmic layer to form the composite laminate assembly configured for being separated into the individual cards.

First claim

The invention claimed is:

1. A laminated core stock sheet for use in a composite laminate assembly for being separated into plural individual cards, the laminated core stock sheet comprising:
a core substrate layer; and
an intermediate filmic layer coupled to the core substrate layer, the intermediate filmic layer including plural conductive bodies arranged in a repeating pattern and that provide at least one of a security feature, a decorative feature, or other functional feature of the individual cards, wherein the plural conductive bodies are spaced apart from each other within the intermediate filmic layer such that the plural conductive bodies prevent conduction of electrostatic discharge through the intermediate filmic layer and outside of the individual cards.

2. The laminated core stock sheet of claim 1 , wherein the plural conductive bodies are laterally spaced apart from each other in two or more directions of a plane within the intermediate filmic layer.

3. The laminated core stock sheet of claim 1 , wherein the plural conductive bodies are arranged in the repeating pattern within the intermediate filmic layer over all or substantially all of a planar surface area of the core substrate layer.

4. The laminated core stock sheet of claim 1 , wherein the intermediate filmic layer has a reflective mirror surface.

5. The laminated core stock sheet of claim 1 , wherein spacing between the plural conductive bodies of the intermediate filmic layer permits wirelessly communicated electromagnetic waves through the intermediate filmic layer.

6. The laminated core stock sheet of claim 5 , wherein the intermediate filmic layer does not inhibit the electromagnetic waves having sub-gigahertz frequencies from passing through the intermediate filmic layer.

7. The laminated core stock sheet of claim 1 , wherein the plural conductive bodies of the intermediate filmic layer are disposed in and spaced apart from each other in a plane that is parallel to the core substrate layer and within the intermediate filmic layer.

8. A composite laminate assembly for being separated into plural individual cards, the assembly comprising:
a first laminated core stock sheet including a first core substrate layer and a first intermediate filmic layer coupled to the first core substrate layer, the first intermediate filmic layer including plural conductive bodies arranged in a repeating pattern that separates the plural conductive bodies from each other, the first intermediate filmic layer providing at least one of a security feature, a decorative feature, or other functional feature of the individual cards;
a second laminated core stock sheet including at least a second core substrate layer, wherein the first laminated core stock sheet and the second laminated core stock sheet are configured to be laminated together;
a first overlay layer configured to be coupled with the first laminated core stock sheet such that the first intermediate filmic layer is disposed between the first core substrate layer and the first overlay layer; and
a second overlay layer configured to be coupled with the second laminated core stock sheet such that the first and second laminated core stock sheets are disposed between the first overlay layer and the second overlay layer,
wherein the plural conductive bodies are spaced apart from each other within the first intermediate filmic layer such that the plural conductive bodies prevent conduction of electrostatic discharge (ESD) through the first intermediate filmic layer and outside of the individual cards.

9. The composite laminate assembly of claim 8 , wherein the plural conductive bodies of the first intermediate filmic layer are laterally spaced apart from each other in two or more directions within a plane of the first intermediate filmic layer.

10. The composite laminate assembly of claim 8 , wherein the first overlay layer includes an outer surface and an opposite surface, and wherein the first intermediate filmic layer is coupled to the opposite surface.

11. The composite laminate assembly of claim 8 , wherein the plural conductive bodies are separated from the outer surface of the first overlay layer by at least one mil.

12. The composite laminate assembly of claim 8 , wherein the plural conductive bodies are arranged in the regular pattern that extends over all or substantially all of planar surface areas of the first laminated core stock sheet and the first overlay layer.

13. The composite laminate assembly of claim 8 , wherein the first intermediate filmic layer has a reflective mirror surface.

14. The composite laminate assembly of claim 8 , further comprising a radio frequency identification (RFID) inlay layer disposed between the first laminated core stock sheet and the second laminated core stock sheet, the RFID inlay layer including one or more RFID devices.

15. The composite laminate assembly of claim 14 , wherein the plural conductive bodies of the first intermediate filmic layer permit electromagnetic waves communicated with the RFID device to wirelessly pass through the first intermediate filmic layer.

16. The composite laminate assembly of claim 15 , wherein the first intermediate filmic layer permits the electromagnetic waves having sub-gigahertz frequencies to pass through the first intermediate filmic layer.

17. The composite laminate assembly of claim 15 , wherein the plural conductive bodies of the first intermediate filmic layer are laterally spaced apart from each other within a plane that is parallel to the first core substrate layer.

18. The composite laminate assembly of claim 8 , wherein the second laminated core stock sheet also includes a second intermediate filmic layer coupled to the second core substrate layer, the second intermediate filmic layer including plural conductive bodies spaced apart from each other that also provide at least one of a security feature, a decorative feature, or other functional feature of the individual cards.

19. The laminated core stock sheet of claim 1 , wherein the plural conductive bodies in the intermediate filmic layer are spaced apart from each other in the intermediate filmic layer such that no conductive pathway extends between two or more of the conductive bodies.

20. The composite laminate assembly of claim 8 , wherein the plural conductive bodies in the first intermediate filmic layer are spaced apart from each other such that no conductive pathway extends between two or more of the conductive bodies.

21. The laminated core stock sheet of claim 1 , wherein the intermediate filmic layer also includes an emboss coating layer having the plural conductive bodies coupled with the emboss coating layer.

22. The laminated core stock sheet of claim 1 , wherein the plural conductive bodies are arranged in the repeating pattern within the intermediate filmic layer over less than all of a planar surface area of the core substrate layer.

23. The composite laminate assembly of claim 8 , wherein the first intermediate filmic layer also includes an emboss coating layer having the plural conductive bodies coupled with the emboss coating layer.
