Abstract (en)
[origin: WO2010015381A2] The invention relates to a method for producing a security element (1), a security element (1) obtained according to the claimed method, transfer materials containing the claimed security elements, and objects of value secured by means of the claimed security elements. The claimed security element (1) comprises at least two functional layers (12, 22), each of which forms a design. The designs are congruous, or one design represents a photographic negative of the other design. In the claimed method, the design of one functional layer (12) is transferred into the other functional layer (22) with the help of an adhesive layer (30). An accurate copy of the design of the first functional layer is reproduced in the adhesive layer, and said copy of the design in the adhesive layer is used for reproducing an accurate copy of said design or the photographic negative thereof in the second functional layer. The design is successfully transferred from one functional layer into the other one as a result of the fact that the adhesive has zones with different adhesiveness because the irradiation penetrates the first functional layer, and only the very adhesive zones adhere to the second functional layer. The zones of the functional layer that do not adhere are removed.
