Method for producing a multilayer body, having the following steps: a) providing a substrate film with a replication layer; b) moulding a surface relief, which appears to the observer in the form of a three-dimensional freeform surface and is formed, in particular, from structures shaped like lenses and generating an enlargement, reduction or distortion effect, into a surface of the replication layer; c) applying a first metallic layer to the surface of the replication layer forming the surface relief; d) applying an at least partially transparent spacing layer to the first metallic layer by wet chemistry, wherein the spacing layer forms a further surface relief in its surface facing away from the replication layer, and wherein the surface relief and the further surface relief at least partially correlate; e) applying a second metallic layer to the spacing layer, wherein at least one of the two metallic layers is formed semi-transparently, or a) providing a substrate film with a replication layer; b) moulding a surface relief, which appears to the observer in the form of a three-dimensional freeform surface and is formed, in particular, from structures shaped like lenses and generating an enlargement, reduction or distortion effect, into a surface of the replication layer; c) applying a first highly refractive dielectric layer to the surface of the replication layer forming the surface relief; d) applying an at least partially transparent spacing layer to the first dielectric layer by wet chemistry, wherein the spacing layer forms a further surface relief in its surface facing away from the replication layer, and wherein the surface relief and the further surface relief at least partially correlate; e) applying a second highly refractive dielectric layer to the spacing layer, wherein the spacing layer is less refractive than the first and the second highly refractive layer. a) providing a substrate film with a replication layer; b) moulding a surface relief, which appears to the observer in the form of a three-dimensional freeform surface and is formed, in particular, from structures shaped like lenses and generating an enlargement, reduction or distortion effect, into a surface of the replication layer; c) applying a first metallic layer to the surface of the replication layer forming the surface relief; d) applying an at least partially transparent spacing layer to the first metallic layer by wet chemistry, wherein the spacing layer forms a further surface relief in its surface facing away from the replication layer, and wherein the surface relief and the further surface relief at least partially correlate; e) applying a second metallic layer to the spacing layer, wherein at least one of the two metallic layers is formed semi-transparently, or a) providing a substrate film with a replication layer; b) moulding a surface relief, which appears to the observer in the form of a three-dimensional freeform surface and is formed, in particular, from structures shaped like lenses and generating an enlargement, reduction or distortion effect, into a surface of the replication layer; c) applying a first highly refractive dielectric layer to the surface of the replication layer forming the surface relief; d) applying an at least partially transparent spacing layer to the first dielectric layer by wet chemistry, wherein the spacing layer forms a further surface relief in its surface facing away from the replication layer, and wherein the surface relief and the further surface relief at least partially correlate; e) applying a second highly refractive dielectric layer to the spacing layer,
