Abstract

The disclosure provides a core layer for an information carrying card, resulting information carrying card, and methods of making the same. A core layer for an information carrying card comprises at least one thermoplastic layer having at least one cavity, an inlay layer, and, and a crosslinked polymer composition. At least one portion of the inlayer layer is disposed inside the at least one cavity of the at least one thermoplastic layer. The crosslinked polymer composition is disposed over the at least one thermoplastic layer and contacting the inlayer layer.

Claims

1. A core layer for an information carrying card comprising:

a thermoplastic layer defining at least one cavity therein, each cavity having a continuous surface defined by and being inside the thermoplastic layer;

an inlay layer, at least one portion of the inlayer layer disposed inside the at least one cavity;

a polymer composition having crosslinking structure disposed over the thermoplastic layer and at least partially into the at least one cavity, and contacting the inlayer layer;

wherein the polymer composition having crosslinking structure comprises a base unit selected from the group consisting of acrylate, methacrylate, urethane acrylate, ester acrylate, silicone acrylate, epoxy acrylate, silicone, urethane and epoxy; and

at least one of a metal containing sheet and a ceramic containing sheet.

2. The core layer for an information carrying card of claim 1 wherein the thermoplastic layer is selected from the group consisting of polyvinyl chloride, copolymer of vinyl chloride, polyolefin, polycarbonate, polyester, polyamide, and acrylonitrile butadiene styrene copolymer (ABS).

3. The core layer for an information carrying card of claim 1 wherein the inlay layer comprises at least one electronic component, wherein the at least one electronic component is partially or fully disposed inside the cavity over the thermoplastic layer.

4. The core layer for an information carrying card of claim 3 wherein the at least one electronic component in the inlay layer comprises at least one integrated circuit.

5. The core layer for an information carrying card of claim 3 wherein the at least one electronic component in the inlay layer comprises at least one light emitting diode (LED) component.

6. The core layer for an information carrying card of claim 3 further comprising a battery connected with the at least one electronic component.

7. The core layer for an information carrying card of claim 3 wherein the polymer composition having crosslinking structure is disposed into the cavity over the thermoplastic layer.

8. The core layer for an information carrying card of claim 1 wherein the polymer composition having crosslinking structure comprises a base unit selected from the group consisting of acrylate, methacrylate, urethane acrylate, ester acrylate, silicone acrylate, and silicone.

9. The core layer for an information carrying card of claim 1 wherein the base unit in the polymer composition having crosslinking structure is urethane acrylate.

10. The core layer for an information carrying card of claim 1 wherein the polymer composition having crosslinking structure does not include a filler.

11. The core layer for an information carrying card of claim 1 wherein the polymer composition having crosslinking structure further comprises a filler.

12. The core layer for an information carrying card of claim 11 wherein the polymer composition having crosslinking structure comprises in the range of about 0.5 wt. % to about 80 wt. % of the filler.

13. The core layer for an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is larger than the size of the inlay layer.

14. The core layer for an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is the same as the size of the inlay layer.

15. The core layer for an information carrying card of claim 1 wherein the size of the at least one cavity on the first thermoplastic layer is the same as the size of a portion of the inlay layer.

16. An information carrying card comprising the core layer of claim 1.

17. The information carrying card of claim 16 further comprising at least one of a metal containing sheet and a ceramic containing sheet.

18. The information carrying card of claim 16 further comprising at least one printable thermoplastic film laminated onto the surface of the thermoplastic layer and the polymer composition having crosslinking structure.

19. The information carrying card of claim 16 further comprising at least one transparent film laminated onto the surface of the printable thermoplastic film.
