ABSTRACT:
A security document is equipped with a security element in the form of a thread or strip that is characterized by, among other things, the property of electrical conductivity. The security element is provided for this purpose with a metal coating associated with a second layer that is also electrically conductive but made of a material that maintains its electrical conductivity in spite of mechanical stress such as bending, stretching, etc. Breaks in the metal layer which might occur when the thread is being embedded in the security document or during daily use thus do not result in a complete interruption in the electrical connection, but are bridged by the second, electrically conductive layer.
