Abstract

This invention relates to a marking for painted objects, preferably motor vehicles, as well as to a method for producing the marking. For this purpose, a paint coat, preferably having several paint layers, is applied to the object and the spectral course of a partial spectrum of the electromagnetic spectrum of the paint coat arranged within an electromagnetic measuring range is changed in a targeted manner such that it has narrow-band extremes of at least 5% relative intensity change.
