The present invention relates to a mono or multi-layer polyester film, a process for producing the mono or multi-layer polyester film, an article comprising the mono or multi-layer polyester film as well as the use of the mono or multi-layer polyester film packaging products, insulating materials, solar, marine or aviation applications, science, electronic or acoustic applications, wires, cables, radio frequency identifications, flexible circuits, graphic arts, stone paper, holograms, filter products, cosmetic products, household products imaging, recording media, or industrial products.

A process includes providing a first layer, which is made of a non-opaque plastic material having an initial thickness, covering an area of the first layer with a patterned plate, pressing the patterned plate against a first surface of the first layer so as to form first and second regions thereon, with the second region being thicker than the first region, and removing the patterned plate from the first surface. The patterned plate comprises a cavity having a size of that corresponds to a window.

Composite cards formed include a security layer comprising a hologram or diffraction grating formed at, or in, the center, or core layer, of the card. The hologram may be formed by embossing a designated area of the core layer with a diffraction pattern and depositing a thin layer of metal on the embossed layer. Additional layers may be selectively and symmetrically attached to the top and bottom surfaces of the core layer. A laser may be used to remove selected portions of the metal formed on the embossed layer, at selected stages of forming the card, to impart a selected pattern or information to the holographic region. The cards may be ‘lasered’ when the cards being processed are attached to, and part of, a large sheet of material, whereby the “lasering” of all the cards on the sheet can be done at the same time and relatively inexpensively.

A method of manufacturing a card according to an embodiment of the present invention includes the steps of: processing a wood sheet; stacking the wood sheet on an inlay sheet including an antenna that will be connected to a COB chip; milling an area corresponding to the chip on the wood sheet, and forming a residual layer of a thickness smaller than that of the wood sheet; exposing end portions of the antenna passing through the residual layer from the inlay sheet located under the residual layer of the wooden sheet; and electrically connecting the chip and the end portions of the antenna.

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.

The disclosure provides a method for forming an information carrying card or a core layer of an information carrying card using a radiation curing, and an apparatus configured to provide such a radiation curing. The method includes providing a carrier layer that defines at least one cavity, providing an inlay layer supporting at least one electronic component, and positioning at least a portion of the inlay layer in the at least one cavity. The method further comprises dispensing a radiation crosslinkable polymer composition over the inlay layer, and irradiating the radiation crosslinkable polymer composition.

The disclosed embodiments generally relate to transaction card constructions, and particularly, to a two-piece transaction card construction. Disclosed embodiments include a generally planar first card component including a first surface and a generally planar second card component including a second surface wherein the first card component is separate from the second card component. In disclosed embodiments, for example, the generally planar first card component and the generally planar second card component may be configured such that one forms a cavity and the other forms an inlay component configured to be seated within the cavity. In other embodiments the generally planar first card component and the generally planar second card component may be configured such that one forms a container and the other forms a lid configured to close the container.

Aspects described herein may allow for a payment card having enhanced edge patterns. The payment card may include a complex edge morphology on the physical card that may make the payment card more likely to be used by consumers and makes the payment card stand out due to the enhanced edge design. The edge of the payment card may be reeded, crenelated, or may include various shapes of various sizes on one or more of the edge walls extending around the payment card. The edge of the payment card may also include dimples, chips, and/or other complex design patterns cut into the face of the payment card close to the edge. The payment card may also include inclusions of other materials, such as metals, ceramic, and/or polymer to be added which fill or partially fill any voids produced by the edge patterns.

An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. The images can produce one or more optical effects.

The present invention relates to a layered structure containing at least one layer (i) comprising a thermoplastic material and at least one further layer (ii) comprising a thermoplastic material bearing at least one embossed hologram, to a process for producing such layer composites and to security documents, in particular identification documents, having the layered structure according to the invention.
