- the reflection layer 14 is for its part arranged between the two spacer layers 12.
- One of the two absorber layers 11 is in turn arranged or applied to the structures 4.
- the structures 4 and other possible layers or plies are no longer shown in greater detail or are only indicated, but are still described below.
- the protective layer 13 can be arranged or provided on the side of the outer absorber layer 11 facing away from the structures 4.
- the protective layer 13 can be provided, but need not be provided.
- the structures 4 can either be formed directly on the carrier layer 8 or the further layer 9 described above can be provided and the structures 4 can be formed on this.
- the previously described intermediate layer 10 can again be provided, which is indicated in dashed lines.
- the security element 1 can again be formed in combination with the structures 4.
