Latest Patents

Kocher holds a patent for a multi-layer printing substrate with hidden information. This security paper consists of a first paper ply, a second paper ply, and a plastic ply made from a thermoplastic polymer material arranged between the paper layers. A strip-shaped tear-off film is embedded between the paper layers on the inner side of the second paper layer and is at least partially embedded into the plastic layer. The hidden information is arranged on the inner side of the first paper ply and is covered by the strip-shaped tear-off film or is placed on the surface of the strip-shaped tear-off film facing the first paper ply. This hidden information can be exposed by tearing off the strip-shaped tear-off film along with a strip of the second paper ply, providing an irreversible method of revealing the concealed data.
