Abstract
A multilayer security document is proposed, wherein a printable carrier material (30) is connected to at least one at least partially transparent outer film or one at least partially transparent outer film composite (10). A photopolymer layer composite (30) is provided between the outer film or the outer film composite (10) and the carrier material (30), the photopolymer layer composite consisting of a photopolymer layer (24), the photopolymer layer being glued on both sides to a photopolymer outer film (22, 26). Information can be exposed into at least one region of the photopolymer layer (24). The photopolymer layer composite (20) is connected to the outer film or the outer film composite (10) and the carrier material (30). An inexpensive method for producing this multilayer security document is also proposed.
