Abstract: A security document including a metal layer comprising an arrangement of diffractive nanostructures arranged periodically in the metal layer to form a diffractive holographic structure forming an arrangement of pixels each comprising a plurality of sub-pixels of distinct colors, a lenticular array comprising convergent lenses positioned facing the metal layer, and a support layer on which the metal layer is disposed so that the metal layer is sandwiched between the lenticular array and the support layer. The metal layer includes perforations formed by focusing laser radiation through the lenticular array on the metal layer, the perforations including at least one group of perforations produced by focusing the laser radiation at a respective angle of incidence to reveal a corresponding personalized image when the security document is observed at this angle of incidence.

Abstract: A laminated structure for an E-document, comprising a first support layer defining at least two flat flaps connected by at least one fold line, the first flap supporting an antenna and a microcircuit device enabling contactless data exchange, the second flap supporting an electromagnetic interference element arranged in relation to the microcircuit device so as to be able to oppose contactless reading and/or writing of the microcircuit device in at least one folded configuration of the structure, the structure having at least one heat-activated or pressure-sensitive adhesive layer making it possible to receive the microcircuit device and/or the antenna and/or the electromagnetic interference element at least in part in its thickness, and/or the flaps having at least one layer of an adhesive and/or a fibrous layer and/or a polymer layer having a different thickness for each of the flaps.
