The invention concerns a process for producing a film element having mutually registered metallic layers (11, 16) and a film element which can be produced by such a process. A first metallic layer (11) provided on a first surface of a flexible single-layer or multi-layer carrier film (10) and a masking layer (13) provided on the second surface of the carrier film (10), opposite to the first surface, are structured in accurate register relationship with each other by means of mutually synchronized structuring procedures. After structuring of the first metallic layer (11) and the masking layer (13) one or more further layers are applied to the first metallic layer (11). Applied to the one or more further layers (15) is a second metallic layer (16) to which a first photoactivatable layer (17) is applied. The first photoactivatable layer (17) is structured by means of trans-exposure through the masking layer (13), the first metallic layer, the one or more further layers and the second metallic layer (16) from the side of the masking layer (13) by means of electromagnetic radiation of a wavelength to which the first photoactivatable layer (17) is sensitive, or the first photoactivatable layer is exposed controlledly through the masking layer from the side of the film body that is opposite to the masking layer.
