Detailed description of the invention

For the purposes of this invention, viewing in incident light is illumination of the security element from one side and observation of the light

Security elements from the same page. A reflection in reflected light is thus present, for example, when the front of the security element is illuminated and also viewed. A reflection in transmitted light is in the sense of this invention

Lighting a security element from one side and a view of the security element from another side, in particular the

opposite side. A reflection in transmitted light is thus, for example, when the back of the security element illuminated and the front of the security element is considered. The light thus shines through the security element.

Form a data carrier substrate by means of a plurality of the data carrier substrate by breaking recesses, which together

Make breakthrough area motif. It is preferred that the apertured recesses forming the aperture region motif be created in the data carrier substrate by the action of laser radiation on the data carrier substrate (i.e., by laser cutting).

The data carrier substrate is in particular a paper substrate or a paper-like substrate.

The breakthrough area motif may be in the form of a pattern or an image, in the form of characters or in the form of an encoding.

In a preferred variant, the aperture region motif is a so-called macroscopic aperture region motif that passes through a plurality of so-called microscopic

Recesses is composed. The microscopic apertures may be in the form of raster elements, e.g. in the form of a dot matrix and / or line grid. A line grid can

in particular by parallel lines, approximately parallel lines,

diverging lines or by a combination of the aforementioned types. As used herein, the term "microscopic" is not to be understood as meaning "micrometer-sized" or the like, but is merely to be understood as relative. The microscopic

breakthrough recesses are each to the viewer with the naked eye, i. without the use of optical aids,

perceptible and in the case of the above preferred variant gives a total image, i. a macroscopic breakthrough area motif.

In a further preferred variant, the Durchbrechungsbereich- motive is composed by several macroscopic erupting recesses. In particular, the macroscopic erupting recesses form a pattern or an image or a part of an image, a character or a string or an encoding. In a further preferred variant, the Durchbrechungsbereich- motif by one or more macroscopic erupting

Recess (s) on the one hand and by a plurality of microscopic erupting recesses on the other hand assembled. The macroscopic erupting recess (or the plurality of macroscopic erupting recesses) forms

in particular a pattern or a picture or a part of a picture, a sign or a sign or a coding. The microscopic apertures may be in the form of raster elements, as described above.

In all configurations, the microscopic apertures may preferably have a dot dimension (in the case of a

Dot grid) or line width (in the case of a line screen) having a width in a range of 0.05 mm to 1 mm, in particular in a range of 0.1mm to 0.4mm. The distance between the adjacent microscopic break-through recesses (center-center) is preferably in a range of 0.05 mm to 1 mm.
