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.
Claims18
A core layer for a plurality of information carrying cards, comprising
- a thermoplastic layer defining a plurality of cavities therein;
- a plurality of inlay layers, each respective inlay layer comprising at least one electronic component, which is partially or fully disposed inside one respective cavity of the plurality of the cavities;
- and
- a crosslinked polymer composition disposed in the plurality of cavities and 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,
- wherein the crosslinked polymer composition at least partially defines an outer surface of the core layer, the inlay layer is fully embedded inside the crosslinked polymer composition, and the outer surface of the core layer is an upper surface of the core layer opposite to a bottom surface of the thermoplastic layer.
A core layer for a plurality of information carrying cards, comprising
- a thermoplastic layer defining a plurality of cavities therein;
- a plurality of inlay layers, each inlay layer comprising at least one electronic component partially or fully disposed inside a respective cavity;
- and
- a crosslinked polymer composition disposed in the plurality of cavities and 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,
- wherein the crosslinked polymer composition at least partially defines an outer surface of the core layer, the plurality of inlay layers are fully embedded inside the crosslinked polymer composition, and the outer surface of the core layer is an upper surface of the core layer opposite to a bottom surface of the thermoplastic layer,
- wherein the at least one cavity has a size the same as or larger than that of the inlay layer.
The core layer of claim 13 wherein each respective cavity has a respective continuous surface profile solely defined by and inside the thermoplastic layer, the continuous surface profile having a respective bottom wall surface and a respective side wall surface.
