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.
