Abstract

La présente invention concerne un élément optique de protection contre la copie comprenant une couche caustique et une couche de masque configurées pour afficher simultanément une image visible reproduisant une image de référence et former une image projetée contenant un motif caustique visible reproduisant un motif de référence, lors de l'éclairage de l'élément optique avec une source de lumière, l'image projetée étant distincte de l'image de référence. L'invention concerne également un procédé de conception d'un motif en relief d'une surface de réorientation de lumière de ladite couche caustique avec les propriétés de transmission de la couche de masque.
