Abstract

L'invention concerne un document de sécurité (1) comprenant un corps de document stratifié (200) pourvu d'un recto et d'un verso. Le corps de document stratifié (200) comporte au moins deux couches de matière opaques (9, 10, 201, 202) pourvues chacune d'un côté intérieur (205) et d'un côté extérieur (206), les côtés intérieurs (205) des au moins deux couches de matière opaques (9, 10, 201, 202) se faisant face, et au moins une couche de matière transparente (203) disposée entre les au moins deux couches de matière opaques (9, 10, 201, 202), et les au moins deux couches de matière opaques (9, 10, 201, 202) comportent des perforations (12, 12'). Dans un plan des couches de matière (9, 10, 201, 202, 203, 204), les faces en coupe transversale des perforations (12, 12') ne présentent pas de conformation à symétrie de rotation et d'autres couches de matière (203), disposées entre les au moins deux couches de matière opaque (9, 10, 201, 202), sont toutes au moins translucides, de préférence sont toutes claires et transparentes. L'invention concerne en outre le procédé associé.
