Patent

CA 2761779

The invention relates to an element (12) that includes an array (14) of raised lines (16), each line (16) including at least one flank (18A, 18B), each of which define an inclination angle (a1) relative to a direction normal (Z) to the array (14). More precisely, the inclination angle (a1) of the flank (18A, 18B) of at least one line (16) of the array (14) gradually changes along said line (16) so as to form, in terms of light reflection, a degraded optical effect that changes based on the observation angle of the security element.

Cet élément (12) comprend un réseau (14) de lignes (16) en relief, chaque ligne (16) comprenant au moins un flanc (18A, 18B) définissant chacun un angle d'inclinaison (a1) par rapport à une direction normale (Z) au réseau (14). Plus précisément, l'angle d'inclinaison (a1) du flanc (18A, 18B) d'au moins une ligne (16) du réseau (14) varie graduellement le long de cette ligne (16) de manière à former en réflexion lumineuse un effet optique dégradé changeant en fonction d'un angle d'observation de l'élément de sécurité.
