A headlight for vehicles having a projection module containing a low beam primary lens and a first light source, a high beam primary lens and a second light source, a secondary lens arranged in the main beam direction in front of the low beam primary lens and the high beam primary lens, a secondary lens by means of which, in a low beam mode, in which only the first light source is activated, a first light bundle emitted from the low beam primary lens is mapped according to a specified low beam distribution and, in a high beam mode, in which the first light source and the second light source are activated, the first light bundle is mapped together with the second light bundle emitted from the high beam primary lens in order to produce the high beam distribution, wherein the high beam primary lens has compensator.

Headlight for vehicles

The invention relates to a process for the production of a multi-layer image, preferably a multi-color image. A transfer film which is applied to a paper ubstrate and which is treated with laser irradiation is used. The transfer film has a laser-sensitive layer and a background layer arranged therebeneath. The laser-sensitive layer comprises laser-sensitive material, for example laser-sensitive pigments or other laser-sensitive coloring agents. The laser-sensitive material in the layer is region-wise bleached by laser irradiation. That results in a so-called laser-induced image component. As it is transparent or partly transparent, the background layer which is arranged therebeneath and which can have a printed image then becomes visible from above in that region. That therefore gives a multi-layer image which is formed by the laser-induced image component and by the background layer jointly.

Multilayer image, particularly a multicolor image

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.

Multilayer body with a first laser-sensitive layer and a second laser-sensitive layer and method for generation of a multilayer image in said multilayer body

The present invention relates to a process for increasing the level of safeguard in respect of forgery of paper documents. For that purpose, applied to the paper document is a transfer film or laminating film having a laser-sensitive layer. This multi-layer body is then treated with laser radiation. In that case, a laser-induced marking is produced in the laser-sensitive layer, for example, by laser-induced bleaching, laser-induced color change or laser-induced blackening. Respective individualization of the document can be effected by way of that laser-induced marking.

Multilayer body with a laser-sensitive layer

The present invention relates to a multi-layer body which is a paper document with a hot stamping film embossed thereon. The hot stamping film has a laser-sensitive layer in which a laser-induced color image is produced by laser treatment. Arranged on the document are further security identifications such as a security print, which is in the form of guilloche patterns, fluorescent threads, and a security strip. Water marks are also provided in the paper document.

Multilayer body with a layer having at least one laser-sensitive material

A lamp for a vehicle includes a light-conducting element. The light-conducting element has at least one in-coupling element arranged between two adjacent light out-coupling elements. A light source is associated with a light in-coupling surface of the light in-coupling element. At least two light-diverting surfaces of the light in-coupling element are associated with respective ones of the light out-coupling elements. The light-diverting surfaces serve to divert light beams radiated from the light source into the respective light out-coupling elements. The light-diverting surfaces of the light in-coupling elements are convexed, or curved, outwardly and have a common focus position for the light source.
