A method for producing a multi-layer body, in particular a security element, in which a partial first layer or partial first layer system is produced on a substrate, wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area. Subsequently, a partial second layer or partial second layer system is produced, wherein the partial second layer or partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas. Finally, the partial first layer or partial first layer system is structured as a mask using the partial second layer or partial second layer system.
A multi-layer body comprising a substrate, a partial first layer or partial first layer system as well as a partial second layer system, wherein the partial first layer or partial first layer system is structured using the partial second layer system as a mask in accurate register with the partial second layer system and wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area and wherein the partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas such that the partial second layer system extends not only over the first partial area covered by the partial first layer or the partial first layer system, but also over the second partial areas not covered by the partial first layer or the partial first layer system, and
