Abstract

L’invention concerne un procédé de fabrication d’un document de sécurité, comprenant des étapes de : a - former des microstructures (21) dans un substrat par pressage d’une matrice présentant des microreliefs en saillie et/ou en creux contre une surface du substrat, b - revêtir les microstructures (21) d’une couche à saut d’indice afin que les microstructures puissent renvoyer un rayonnement lumineux incident, et c - recouvrir la surface du substrat, y compris les microstructures (21) et la couche à saut d’indice, par un film de protection (3) en matériau polymère, dans lequel la couche à saut d’indice présente un indice de réfraction différent d’un indice de réfraction du film de protection (3) en matériau polymère.
