Abstract

L’invention concerne un document (10) comportant une structure multicouche composée d’un substrat opaque entouré de part et d’autre, par au moins une couche (14, 15) transparente à la lumière et sensible à un faisceau laser, caractérisé en ce qu’au moins une zone d’une face du substrat opaque comporte un motif de sécurité (12) réalisé en un matériau insensible audit faisceau laser, de sorte qu’un faisceau laser (17) dirigé à travers une couche transparente (14, 15) située d’un premier côté dudit substrat pour créer dans cette couche transparente (14, 15) des micro-perforations (18) se trouve bloqué par ledit motif de sécurité (12) et ne traverse pas les couches de matière situées sur un second côté dudit substrat.
