  • a further layer is disposed between the carrier layer and the removable by laser radiation color layer, which reflects the laser radiation, for visible light, however, is transparent or at least translucent.
  • the invention is therefore the object of developing a generic security element such that the disadvantages of the prior art is eliminated and the protection against counterfeiting is further increased.
  • a laser beam is directed to the front side of the substrate, wherein the laser beam removes at least a first portion of the substrate located between the front side of the substrate and the reflector layer so that at least one window is formed on the front side of the security element extending to extends to the reflector coating.

Furthermore, it is possible, for example, for the window of the first subregion to be one half of a star forms and the second part of the other half, so that both parts together form the complete star.

When light strikes one side of the object, a certain portion of the light is transmitted to the other side of the object and exits there again. The larger the percentage of the passing light with respect to the incident light, the more translucent the object is. If the percentage is at least 90%, ie if the object allows the incident light to pass through almost unimpaired, as in the case of a window, the object is called transparent. On the other hand, an object which transmits less than 10% and preferably about 0% of the incident light, ie in which the amount of transmitted light relative to the incident light is low or near zero, is said to be opaque or non-translucent.
