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 inlay 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 inlay layer.

Claims

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

a thermoplastic layer defining at least one cavity therein, the at least one cavity having a continuous surface profile solely defined by and being inside the thermoplastic layer, the continuous surface profile having a bottom wall surface and a side wall surface, the thermoplastic layer comprising at least one thermoplastic material;

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

a crosslinked polymer composition disposed over the thermoplastic layer and at least partially into the at least one cavity, and contacting the inlay layer.

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 crosslinked polymer composition is disposed into the cavity over the thermoplastic layer.

8. The core layer for an information carrying card of claim 1 wherein the crosslinked polymer composition comprises

a base unit selected from the group consisting of acrylate, methacrylate, urethane acrylate, ester acrylate, silicone acrylate, epoxy acrylate, silicone, urethane and epoxy.

9. The core layer for an information carrying card of claim 8 wherein the base unit in the crosslinked polymer composition is urethane acrylate or epoxy.

10. The core layer for an information carrying card of claim 1 wherein the crosslinked polymer composition has no filler or further comprises a filler.

11. The core layer for an information carrying card of claim 10 wherein the crosslinked polymer composition comprises in the range of about 0.5 wt. % to about 80 wt. % of the filler.

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

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

15. The core layer for an information carrying card of claim 1 wherein the crosslinked polymer composition is disposed over a top surface of the thermoplastic layer above and outside the cavity so as to form a continuous surface of the crosslinked polymer composition throughout the core layer.

16. The core layer for an information carrying card of claim 15 wherein the crosslinked polymer composition is disposed over the top surface of the thermoplastic layer at a thickness in the range of from 1 micron to 100 microns.

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

18. The information carrying card of claim 17 further comprising at least one printable thermoplastic film laminated onto the surface of the thermoplastic layer and the crosslinked polymer composition.

19. The information carrying card of claim 17 further comprising at least one transparent film laminated onto the surface of the printable thermoplastic film.
