| 摘要 |
The invention relates to a security element for producing value documents, which comprises at least one image (11), said image (11) being formed by a lattice structure (4) that has a plurality of channel-like microcavities (5, 6), the microcavities (5, 6) having a structural width (w) of 0.5 µm to 3 µm and an aspect ratio of 0.4 or greater, wherein a metal-containing coating is applied onto the lattice structure (4), and wherein the channel-like microcavities (5, 6) in the lattice structure (4) are separated from each other in each case by strips (7) which are flat and each have a width of more than 200 nm and at most 1200 nm. |
