Information carrying card comprising a cross-linked polymer composition, and method of making the same
First Claim
1. A core layer for an information carrying card, comprisinga thermoplastic layer defining at least one cavity therein, each cavity having a continuous surface defined by and inside the thermoplastic layer;
- an inlay layer comprising at least one electronic component, the at least one electronic component partially or fully disposed inside the at least one cavity;
a crosslinked polymer composition disposed into the at least one cavity and directly contacting the at least one electronic component, the crosslinked polymer composition comprising;
a base polymer resin selected from the group consisting of urethane acrylate, ester acrylate, silicone acrylate, epoxy acrylate, methacrylate, silicone, urethane and epoxy; and
a particulate thermoplastic filler wherein the particulate thermoplactic filler comprises polyvinyl chloride (PVC) or PVC modified with a copolymer of vinyl chloride and at least another monomer selected from the group consisting of vinyl ester, vinyl acetate and vinyl ether.

Abstract
The disclosure provides a cross-linkable polymer composition, a core layer for an information carrying card comprising such cross-linked composition, resulting information carrying card, and methods of making the same. A crosslinkable polymer composition comprises a curable base polymer resin in a liquid or paste form, and a particulate thermoplastic filler. The base polymer resin is selected from the group consisting of urethane acrylate, silicone acrylate, epoxy acrylate, urethane, acrylate, silicone and epoxy. The particulate thermoplastic filler may be polyolefin, polyvinyl chloride (PVC), a copolymer of vinyl chloride and at least another monomer, or a polyester such as polyethylene terephthalate (PET), a compound or blend thereof.
