Abstract
A security element, comprising at least two contiguous areas having an identical or different coloring which can vary depending on the inclination of the incidence and, therefore, reflection of direct light or depending on the type of incident light. The security element also has a single graphic marking which crosses with continuity the two areas having variable coloring so that the graphic marking straddles the two areas so that it is perfectly aligned, without having discontinuities of any kind. Moreover, the effect of this graphic marking is perfectly visible both when the security element is viewed from the recto and when it is viewed from the verso.
