Application 2553/KOLNP/2005 published 2006-10-20, filed 2005-12-09
The invention relates to a security element, preferably for documents of value, which at least has one area with a diffraction structure, which under specific viewing conditions reconstructs a diffractive image. This area has subareas, which do not take part in the reconstruction of the diffractive image, and which represent a recognizable information. Essential is that the information represented by the subareas is recognizable mainly only under the viewing conditions, under which the diffractive image can be perceived. (FIG. 15)
