Abstract (en)
[origin: WO9013877A1] A security document consists of at least two layers of electrically conductive material in which a security element in the form of a transparent thread is embedded. At least some areas of one layer are transparent or semireflecting. The semireflecting layer cooperates with the distinguishing signs on the thread so that the distinguishing signs are substantially concealed in incident light but visually recognizable when back-lit.
