Abstract

A laminate composite composed of at least two laminations (1, 7) and an imprint located between them (3). The lamination (7) includes at least two layers (4, 5, 6). One layer (5) includes a UV absorber to protect the imprint. This layer (5) is characterized by having a lower density than the other layers (4, 6). The other layers (4, 6) preferably have a density that is higher relative to the one layer (5) by a factor of 1.005, in particular by a factor of 1.01, preferably by a factor of 1.015.
