Abstract

La présente invention se rapporte notamment à un élément de sécurité pour un document sécurisé qui est constitué d'un support, comprenant un réseau de lignes parallèles (2) en relief, notamment orientées selon une direction privilégiée X, qui présentent chacune une largeur L, chaque ligne en relief (2) comportant un profil ayant au moins une crête (21) et un sillon (20), ledit réseau étant au moins en partie coloré et constitué d'une répétition de bandes (3) contiguës ou adjacentes, bandes (3) de largeur L' formées chacune de N filets (30-32), N étant un entier supérieur ou égal à deux, contigus ou adjacents avec, le cas échéant, un espace entre filets ayant une largeur plus petite que la largeur d’un filet, ces N filets (30-32) étant d'au moins deux couleurs différentes, lesdites bandes (3) s'étendant sensiblement parallèlement aux lignes en relief (2) dudit réseau, caractérisé par le fait que, dans au moins une région dudit réseau coloré, les filets (30-32) d'au moins une bande (3) se propagent d’une extrémité à l’autre de cette région selon une fonction continue F(x), en partie dérivable et dont la dérivée est non constante et qu’il existe, au sein de ladite région, un intervalle de longueur Li visible à l’œil nu dans lequel la dérivée de ladite fonction F(x) est comprise entre L/(2Li) et 3L/Li, ou entre -3L/Li et –L/(2Li). Figure 11The present invention relates in particular to a security element for a secure document which consists of a support, comprising a network of parallel lines (2) in relief, in particular oriented in a preferred direction X, which each have a width L, each raised line (2) comprising a profile having at least one crest (21) and a furrow (20), said network being at least partly colored and consisting of a repetition of contiguous or adjacent strips (3), strips ( 3) of width L' each formed of N threads (30-32), N being an integer greater than or equal to two, contiguous or adjacent with, where appropriate, a space between threads having a width smaller than the width of a net, these N nets (30-32) being of at least two different colors, said strips (3) extending substantially parallel to the raised lines (2) of said network, characterized in that, in at least one region of said colored network, the threads (30-32) of at least one strip (3) propagate from one end to the other of this region according to a continuous function F(x), partly differentiable and whose derivative is non-constant and there exists, within said region, an interval of length Li visible to the naked eye in which the derivative of said function F(x) is between L/(2Li) and 3L/Li, or between -3L/Li and –L/(2Li).
