Information carrying card comprising a cross-linked polymer composition, and method of making the same
First Claim
1. A method for forming a core layer of an information carrying card, comprising:
- forming a first thermoplastic layer defining at least one cavity extending from a major surface, the first thermoplastic layer comprising at least one thermoplastic material;
disposing an inlay layer comprising printed circuit board (PCB) partially or fully into the at least one cavity, the inlay layer comprising at least one integrated circuit, at least one wire and a supporting film; and
dispensing a crosslinkable polymer composition partially or fully over and directly contacting the inlay layer in the at least one cavity so as to form said core layer of the information carrying card, the crosslinkable polymer composition comprising;
a curable base polymer resin in a liquid or paste form, the base polymer resin selected from the group consisting of urethane acrylate, silicone acrylate, epoxy acrylate, methacrylate, silicone, urethane and epoxy; and
a particulate thermoplastic filler.

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.
