Claim One:
1. A multi-layer image, in particular a multi-color image, including a substrate preferably comprising paper material and a single-layer or multi-layer structure applied thereto using a transfer film, in particular a hot stamping film, or a laminating film, wherein the layer structure has a layer which has a laser-sensitive material—said layer being referred to hereinafter as the laser-sensitive layer—and which is changed at least region-wise by the action of laser with the formation of at least one laser-induced image component and the multi-layer image or at least a portion of the multi-layer image is formed from the laser-induced image component and a background layer and/or a foreground layer, in that the laser-induced image component is arranged in at least partially overlapping relationship with the background layer or is arranged at least partially overlapped by the foreground layer, so that the background layer or the laser-induced image component respectively from above is visible only region-wise and/or is visible more or less translucently, wherein the laser-sensitive material is in the form of a mixture of various laser-sensitive components, wherein the mixture is composed of two and preferably three different coloring agent components, preferably pigment components, wherein each of said two or three components, preferably each component of the mixture, is bleachable by means of laser under respective laser conditions which are specific for the component and/or wherein the mixture is composed of two and preferably three different color-forming components, preferably color-forming coloring agents, wherein each of said components and preferably each component of the mixture is color-variable by means of laser under respective laser conditions which are specific for the component.
