A multilayer body is disclosed, comprising two laser-sensitive layers (4, 32). Said multilayer body is a laminated body of overlay films (30, 32), inlays (90, 90) and further overlay films (30,30). The upper overlay film (30) comprises a layer structure applied to the underside thereof by application of a hot-stamp film. The layer structure comprises a lacquer layer (50), a reflection layer (5r), a laser-sensitive layer (4), a background layer (5) and an adhesive layer (6). A diffraction and/or hologram structure (5b) is embodied in the lacquer layer (5c), the reflection layer (5r) and the laser-sensitive layer (4). The second laser-sensitive layer is embodied as a carbon-doped overlay film (32). A laser-induced, preferably coloured image component can be generated in the upper laser-sensitive layer (4) and a further, preferably grey-scale image generated in the carbon-doped laser-sensitive layer (32) thereunder by means of laser treatment. A laser-induced multilayer image can thus be produced. |
