摘要:
The article includes a substrate which is composed of a single ply that contains both a structure for generating a viewable optically variable effect, such as a hologram, and carries an indicia receptive coating. The indicia receptive coating covers the single ply such that at least part of the optically variable effect is visible. The indicia receptive coating may receive printed indicia such as security indicia, alphanumeric character shapes, symbols, and bar codes. The article with the single ply that contains viewable optically variable effect and also carries the printed indicia, is more tamper resistant than previous identification documents. It is very difficult, if not impossible, to alter the printed indicia without also altering the structure that generates the viewable optically variable effect or vice versa.
