The present invention relates to a process for the production of strongly adherent (embossed) films on flexible substrates, security elements, obtainable by the process and security documents, comprising the security elements. By coating a flexible substrate first with a primer layer and then with an embossed film the adherence of the embossed film to the substrate is improved while keeping the optical performance of the embossed film. 本发明涉及一种在柔性基材上制备强粘附性(压花)膜的方法，可通过所述方法获得的安全元件，以及包括所述安全元件的安全文件。通过首先用底漆层然后用压花膜涂覆柔性基材，压花膜对基材的粘附性得以改善，同时压花膜的光学性能得以保持。
