    Abstract: Method for producing an aluminum foil with integrated security features. An aluminum foil is rolled down to a thickness of less than 150 ?m in a plurality of cold rolling passes, texturing that runs in the direction of rolling being induced simultaneously on both surface sides of the foil. In a final cold rolling pass, the foil is fed to a working roller pair, in which, on at least one roller surface, the relief-like surface structuring generated in the rolling direction by grinding was reduced on the basis of contrast and motif in a region of 10 to 50% relative to the average surface roughness to form a motif for a security feature that is transferred to the surface side of the foil facing the roller surface. The generated aluminum foil has a glossy appearance on both sides such that the security feature rises clearly due to its dull appearance.
