A flexible adhesive imprint of the safe and anti - falsification, official document comprising such a card and method of manufacture of this label

摘要

The present invention relates to a flexible adhesive imprint of anti - falsification comprising at least one integrated circuit (12) fixed on a face (2) with a layer, called the base layer (1), so as to be in electrical contact with the terminals (4, 6) of the electrical connection of at least one antenna (3) of the contactless transmission, a plurality of layers to be printed on each other, at least one layer (16) of external adhesive, the adhesion force of at least a portion of at least one layer, called the separable layer (9), which is printed on the base layer (1), and the adhesive power of at least one layer (16) of external adhesive, being adapted so that the separable layer (9) is separated at least partially of the base layer (1) by causing a deterioration of the operation of the microcircuit in the case of an attempt to unglue after application and bonding of the adhesive on a label.
