Abstract
Described is a multi-layer body having two laser-sensitive layers. The multi-layer body is a body laminated from the overlay films, the inletsand the further overlay films. At its underside the upper overlay filmhas a layer structure applied there, by the application of a hot stamping film. The layer structure comprises a lacquer layer, a reflection layer, a laser-sensitive layer, a background layerand an adhesive layer. A diffraction and/or hologram structureis provided in the lacquer layer, the reflection layerand the laser-sensitive layer. The second laser-sensitive layer is formed by the carbon-doped overlay film By means of laser treatment, it is possible to produce a laser-induced, preferably colored image component in the upper laser-sensitive layerand a further laser-sensitive image component, preferably in the form of a gray scale image, in the subjacent carbon-doped laser-sensitive layer. A laser-induced multi-layer image is formed in that way.
