Abstract: front page image
(EN)The security substrate comprises an at least partially light transmitting carrier supporting a security feature and the security feature comprises at least first and second layers at least one of which covers an area which is less than a full surface area of the carrier and which at least partially overlaps the other layer. The layers have substantially the same colour and texture and the reflective contrast ratio of the overlapping areas and the non- over lapping areas is less than 20% and the transmissive contrast ratio of the overlapping areas and the non-overlapping areas is greater than 3%.
(FR)L'invention concerne un substrat de sécurité comprenant un support transmettant au moins partiellement la lumière, soutenant un élément de sécurité. L'élément de sécurité comprend au moins des première et deuxième couches, au moins une couche couvrant une zone inférieure à la zone de surface totale du support et chevauchant au moins partiellement l'autre couche. Les couches présentent sensiblement une couleur et une texture identiques. Le rapport de contrastes de réflexion des zones chevauchantes et des zones non chevauchantes est inférieur à 20% et le rapport de contrastes de transmission des zones chevauchantes et des zones non chevauchantes est supérieur à 3%.
