发明名称 Polycarbonate-based security and/or valuable document with a hologram in the card body
摘要 Security documents and/or documents of value comprise at least one layer (A1) containing at least one poly- or copolycarbonate, at least one further layer (A2) comprising at least one poly- or copolycarbonate, and at least one layer (P) containing at least one photopolymer in which the hologram is integrated. The layer (P) is partially arranged between the layers (A1) and (A2), of which at least one layer is transparent and is connected with each other in sections. An independent claim is included for producing security documents and/or documents of value, comprising forming a layer stack from the layers (A1), (P), (A2), and optionally (K), where the layers (P) and optionally (K) are only located between the layers (A1) and (A2), and then laminating the layer stack to the security documents and/or documents of value.
