Abstract
The invention relates to a security document (3) in the form of a multilayer film body for viewing in incident light and in transmitted light. The security (3) element has a carrier film (31) and a partial metallic reflective layer (34) in a first region (40) that is transparent or semi-transparent when viewed by a human in transmitted light. In the first region (40), first zones (41) which are provided with the metallic reflective layer, and second zones (42) which are not provided with the metallic reflective layer, are alternately arranged, the centers of gravity of consecutive first zones (41) being interspaced at less than 300 .mu.m. The first region (40) has at least one patterned region with dimensions >300 .mu.m and at least one background region, adjoining the patterned region and at least partially enclosing the background region, the distances of consecutive second regions (42) in the patterned region differing by 5 to 30% in relation to the distances of consecutive second regions (42) in the background region, thereby making an information that is defined by the form of the patterned region visible in transmitted light when viewed by a human.
