Abstract

The present invention relates to a method for producing a security element (), to a security element () obtainable by the method according to the invention, to transfer materials having the security elements according to the invention, and to objects of value secured by the security elements according to the invention. The security element () according to the invention has at least two functional layers (), whereby each functional layer forms a motif and the motifs are either congruent, or one motif represents a photographic negative of the other motif. In the method according to the invention, the motif of one functional layer () is transferred into the other functional layer () with the help of an adhesive layer (). In so doing, there is reproduced in the adhesive layer an exact image of the motif of the first functional layer, and said image of the motif in the adhesive layer is in turn employed for reproducing an exact image of said motif or of its photographic negative in the second functional layer. The transfer of the motif from one functional layer into the other is achieved by the adhesive having areas of varying adhesive strength, induced by irradiation through the first functional layer, and bonding to the second functional layer only in the strongly adhesive areas. The non-bonded areas of the functional layer are removed.
