摘要： A method for integrating a hologram into the body of a security document that has a laminated body. The method includes: providing a holographic film having a backing substrate layer and a photo layer; providing additional substrate layers; carrying out a laminating process in order to form the laminated body, the holographic film together with the additional substrate layers being collated to form a substrate layer stack and being combined, together with the additional substrate layers, in a high-pressure, high-temperature laminating method to form the laminated body. There is also described a corresponding security document body.

摘要： The invention relates to a method for making a structure with at least a first polymer layer and a second polymer layer, each made from a polycarbonate polymer based on bisphenol A, and in between the first polymer layer and the second polymer layer an intermediate layer being arranged, comprising the following steps: a) the intermediate layer is applied at least on a partial region of the first polymer layer, b) optionally the intermediate layer is dried, c) the first polymer layer is coated on the side, on which the intermediate layer is arranged, with a liquid preparation comprising a solvent or a mixture of solvents and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, the preparation covering the intermediate layer, d) optionally a drying step is made after step c), e) after step c) or step d), the second polymer layer is placed on the first polymer layer, covering the intermediate layer, f) the first polymer layer and the second polymer layer are laminated with each other under pressure, at a temperature from 120° C. to 230° C. and for a defined time.

摘要： A security object has a document body. A lens array is formed on a top side and first information is stored in the document body. The optical detectability of the first information through the lens array is dependent on a detection direction. The document body has a top view section, in which the document body has a material layer that is translucent or opaque, and adjacent thereto a window section, in which the document body is formed of a material transparent in volume between a top side and a bottom side. The lens array extends over part of the window section and over part of the top view section and spans a section boundary between the sections. The first information also is formed partially in the top view section and partially in the window section and, in the window section, laser-marked, static second information is stored in the document body.
