A transfer film which comprises a carrier film and an electrical functional layer is applied to the adhesive layer. The carrier film is pulled off the film body comprising the base film, the adhesive layer and the electrical functional layer, wherein in a first region structured in pattern form the electrical functional layer remains on the base film and in a second region structured in pattern form the electrical functional layer remains on the carrier film and is pulled off the base film with the carrier film.
