Abstract

L'invention concerne un support de données, par exemple un document de valeur, comprenant un substrat de support de données et un élément de sécurité appliqué sur le substrat de support de données. La face du substrat de support de données, comprenant l'élément de sécurité, définit la face avant du support de données et le substrat de support de données, dans la zone de l'élément de sécurité, comprend des régions présentant une transmission de lumière accrue et des régions présentant une transmission de lumière moindre, qui forment conjointement un premier motif. L'élément de sécurité contient un substrat de support transparent comportant une couche fonctionnelle semi-transparente. La couche fonctionnelle semi-transparente est conçue de telle manière que (i) le support de données, lorsque la face avant de ce dernier est observée en lumière incidente, présente une première couleur identifiable visuellement, et, lorsqu'elle est observée en lumière transmise, présente une deuxième couleur identifiable visuellement, et (ii) le premier motif, lorsque la face avant du support de données est observée en lumière incidente, est imperceptible et, lorsque le support de données est observé en lumière transmise, est perceptible.
