Abstract

La présente invention concerne un corps comportant des motifs d'image potentielle formés à l'intérieur, et dans lequel les motifs formés dans un substrat et les motifs formés dans une couche de masquage optique sont combinés de façon telle que les motifs ne peuvent pas être observés avec une lumière réfléchie, mais que les images potentielles peuvent être observées avec une lumière émise, prévenant ainsi la contrefaçon. Dans au moins une partie d'une surface du substrat, une pluralité de premiers éléments présentant un facteur de transmission supérieur à celui du substrat est agencée selon la première direction et au premier pas pour former le premier motif, et les phases des premiers éléments sont partiellement différenciées les unes des autres, divisant de ce fait le premier motif en parties potentielles et en parties d'arrière-plan ; la couche de masquage optique faite d'un matériau de masquage optique est formée sur la surface dans laquelle est formé le premier motif ; dans au moins une partie de la couche de masquage optique, une pluralité de seconds éléments est agencée selon la seconde direction et au second pas pour former le second motif ; le premier motif et le second motif sont agencés de façon à se recouvrir l'un l'autre.
