This invention relates to film which is lettered with a laser beam comprising at least one protective film which is transparent to the laser beam, at least one opaque layer which is ablated by the laser beam, and at least one contrast-forming layer on its bottom. The abatable layer is preferably a metallic layer and can have a color like the contrast-forming layer. The color of the metallic layer is different from the color of the contrast-forming layer. The contrast-forming layer is either applied, imprinted or varnished onto the metallic layer. The contrast-forming layer can be at least one plastic film. On a side of the contrast-forming layer facing away from the metallic layer there is an adhesive layer which is covered with a carrier material, for example, an adhesive-repellant carrier film.

[ What is claimed is:] [1.] A film to be lettered with a laser beam comprising:at least one protective film which is transparent to said laser beam;at least one substantially metallic opaque layer having at least one first color and being applied onto a bottom surface of said at least one protective film, said substantially metallic opaque layer being selectively ablated by said laser beam in areas where the metallic layer is irradiated by said laser beam, said at least one protective film sealing said substantially metallic opaque layer before, during, and after ablation of said substantially metallic opaque layer;at least one contrast-forming layer applied to said at least one substantially metallic opaque layer, said contrast-forming layer having at least one color which is contrasting to said first color and being substantially resistant to said laser beam, andan adhesive layer applied to said at least one contrast-forming layer.
