Abstract

L'invention concerne un document de valeur et de sécurité qui est constitué d'un substrat pourvu d'une face avant et d'une face arrière. Une couche de couleur est appliquée sur la face avant ou arrière du substrat. Un premier motif sous la forme d'un dessin, d'un caractère ou d'un codage est incorporé dans la couche de couleur. Le premier motif est réalisé sous la forme d'une structure de gaufrage qui est constitué d'une pluralité d'éléments de gaufrage en relief présentant des surfaces d'orientations différentes et présente un premier effet d'inclinaison ou de mouvement, lorsque le document de valeur et de sécurité es incliné, en raison du fait qu'au moins deux groupes différents d'éléments de gaufrage ayant des paramètres caractéristiques différents reflètent une lumière incidente dans différentes régions de l'espace. Les éléments de gaufrage ont chacun une dimension latérale de plus de 30 µm et une hauteur de plus de 10 µm. L'invention concerne en outre un procédé de fabrication d'un document de valeur et de sécurité correspondant. Selon l'invention, le premier motif est combiné avec un deuxième motif sous la forme d'une figure, d'un dessin, ou d'un code. Le deuxième motif est disposé sur le même côté du substrat que le premier motif. Le deuxième motif se présente sous la forme d'une structure de gaufrage, qui est constituée d'une pluralité d'éléments de gaufrage en relief présentant des surfaces d'orientations différents. Les éléments de gaufrage qui forment le deuxième motif présentent un deuxième effet d'inclinaison ou de mouvement, en raison du fait que différents groupes d'éléments de gaufrage présentent différentes paramètres caractéristiques réfléchissent la lumière incidente vers différentes zones spatiales. Les éléments de gaufrage présentent chacun une dimension latérale de moins de 30 μm et une hauteur de moins de 10 μm. De plus, la figure, le dessin ou le code du premier motif sont au moins en partie adaptés à la figure, au dessin ou au code du deuxième motif.
