Abstract

The present invention relates to a method for producing a security element (1), to a security element (1) 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 with the security elements according to the invention. The security element (1) according to the invention has two functional layers (12, 22) which are bonded together by means of a resist layer (30). The resist layer (30) has a pattern which is employed to generate a congruent pattern in the first functional layer (12). Then the pattern of the resist layer (30), and thus also of the first functional layer (12), is exactly reproduced in the second functional layer (22). This is achieved by bonding the second functional layer (22) in the form of the pattern of the resist layer (30). The non-bonded areas of the second functional layer (22) are removed, thereby forming negative writing.
