Abstract (en)

[origin: WO2022053403A1] A method for producing a composite panel (100) with a hologram, at least comprising the steps of: a) providing a first panel (1) and a second panel (2), b) - arranging a masking strip (4) on a surface (III) of the first panel (1) such that the masking strip (4) delimits a section (7) for a hologram element (5), - applying a photosensitive material (15) as a hologram element (5) at least in the section (7) delimited by the masking strip (4), c) removing the masking strip (4) such that a peripheral edge (8) of the hologram element (5) is uncovered, d) generating at least one hologram by exposing the hologram element (5), e) forming a layer stack made of the first panel (1), a thermoplastic interlayer (3) and a second panel (2), wherein the hologram element (5) is arranged between the two panels (1, 2), f) interconnecting the first panel (1) and the second panel (2) by way of the thermoplastic interlayer (3) to form a composite panel (100) within the scope of a lamination method.
