摘要:
An article may include a biodata page defining a perimeter including an edge and a hinge layer attached to at least a portion of the biodata page. The hinge layer comprises a cross-linked polyurethane. In some examples, the hinge layer may include a cross-linked thermoset polyurethane.
摘要:
A laminate containing an image is produced by printing the image (12) on a layer (11) of a high temperature glue which has been applied to a layer of a transparent medium (10). The image is printed on the glue layer using carbon or a carbon-containing compound that does not flow when applied to the glue surface. The combination of transparent medium, high temperature glue and image is then bonded to a substrate (13) using a thermal bonding process to produce a laminate of the transparent medium and the substrate. The image is not distorted by the thermal bonding process, but remains clearly visible through the transparent medium. Typically the transparent medium will be a polyester film or a sheet of glass beads dispersed in glue. One or more additional layers (27) may be bonded to the substrate (13) to increase the stiffness of the product laminate.

A plate for hot press capable of maintaining the degree of vacuum therein in the form of being separated from a deaerator, a hot press device easily allowing a change in arrangement layout of a press part, and a card manufacturing device capable of manufacturing a variety types of cards by one unit of the device, wherein a check valve device (101h) holding the state of vacuum in a base material storage part (101c) formed between a pair of plate members (101a) and (101b) is installed on the plate for hot press (101), press parts (103A) to (103C), (104A), and (104B) forming laminated parts (103) and (104) are disposed in series, transport rails (108A) and (108B) for transporting the plate for hot press (101) are disposed vertically in two stages, and transport means (118A), (118B), (151A), and (151B) are installed for circulatingly transport the plate for hot press between the transport rails.
摘要:
A security document, banknote, bond, travellers check, passport or token, including a substrate (1), said substrate having a device including a first macro-embossing (2, 3) of the substrate having a predetermined feature, and a second micro-embossing of smaller dimensions formed in or on said predetermined feature of said embossing. The first embossing being formed to hide and reveal said second embossing at predetermined viewing angles alpha, beta. The macro-embossing may comprise lines having a height of about 20 microns and a spacing of 80 microns, and the micro-embossing in the form of lines or dots (4) to a height of about 2 to 5 microns. The lines have a predetermined height (H) and a predetermined spacing (S) such that the ratio S:H is typically from about 6:1 to 2:1. A transparent portion or clear window (W) of a polymer substrate (1) can be provided with embossing such that the first embossing is able to hide and reveal the finer second embossing at various viewing angles by using the gloss and transmission properties of the transparent substrate rather than the traditional reflection and absorption properties of the printed media.
