    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.

    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.
