Abstract:
1. A method for producing a multilayer element, where a) on and/or in a carrier ply having a first side and a second side, a single-layer or multilayer decorative ply having a first region and a second region is formed, the decorative ply, viewed perpendicular to the plane of the carrier ply, having in the first region, a first transmittance and in the second region a second transmittance greater in comparison to the first transmittance, said transmittances relating to electromagnetic radiation having a wavelength suitable for photoactivation, b) at least one layer to be structured is disposed on the first side of the carrier ply, c) a resist layer which can be photoactivated by means of said electromagnetic radiation is disposed on the first side of the carrier ply in such a way that the resist layer is disposed on the side of the at least one layer to be structured that is remote from the carrier ply, and the decorative ply is disposed on the other side of the at least one layer to be structured, d) the resist layer is exposed from the second side of the carrier ply by means of said electromagnetic radiation, the decorative ply serving as an exposure mask through the design of the first region and of the second region, and e) the at least one layer to be structured and the resist layer are structured in register with one another by means of structuring operations synchronized with one another.
