The invention relates to a method for the reduction of the natural vibration (resonance) of a component (). According to the invention a vibration behavior of component () is determined, wherein to each of the positions having vibration amplitudes, which exceed a preset threshold value, an attenuation element () is locally mounted, which is formed as a multilayered adhesive element including a support layer () and a self-adhesive damping mass. Moreover the invention relates to an attenuation element () for the reduction of the natural vibrations of a component (). According to the invention the attenuation element () is formed as a multilayered adhesive element of a support layer () and a self-adhesive damping mass (), wherein the support layer () is formed of a bend-resistant material and the damping mass () preferably is formed of butyl rubber.

The invention relates to an inscribable security film, in particular for use in the automotive sector, and to a method for inscribing it. The security film contains an identification medium which is capable of diffusion and is locally liberated or fixed selectively by means of a contactless inscription process. If the security film is adhesively bonded to a substrate, the identification medium causes permanent marking of the substrate, which ensures unambiguous identification of the object in question.
