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.

Method for integrating a hologram into a security document body and security document body

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.

Security object having a dynamic and static window security feature and method for production

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&#xb0; C. to 230&#xb0; C. and for a defined time.

The invention relates to a security element (). The security element () has a viewing side and a back side that is opposite the latter. The security element comprises at least one luminous layer () that can emit light (), and at least one mask layer () that, when the security element () is viewed from the viewing side, is arranged in front of the at least one luminous layer (). The at least one mask layer () has at least one opaque region () and at least two transparent openings (). The at least two transparent openings () has a substantially higher transmittance than the at least one opaque region () in respect of light () emitted by the at least one luminous layer (), preferably a transmittance that is at least 20% higher, particularly preferably a transmittance that is at least 50% higher.

Security element

The invention relates to a security element (). The security element () has a viewing side and a back side that is opposite the latter. The security element comprises at least one luminous layer () that can provide light (), and at least one mask layer () that, when the security element () is viewed from the viewing side, is arranged in front of the at least one luminous layer (). The at least one mask layer () has at least one opaque region () and at least two transparent openings (). The at least two transparent openings () has a substantially higher transmittance than the at least one opaque region () in respect of light () provided by the at least one luminous layer (), preferably a transmittance that is at least 20% higher, particularly preferably a transmittance that is at least 50% higher.

The invention relates to a security element (), in particular in the form of a multi-layer flexible film body, with a top side facing an observer and a back side facing away from the observer, as well as a method for the production thereof. The security element () has one or more light-emitting elements arranged in a first area () of the security element which radiate light when activated and in particular are formed in each case of a self-luminous, electrically operated, display element. The security element () has, in the first area (), one or more transmissive diffraction structures. The one or more transmissive diffraction structures are arranged such that at least a part of the light radiated by the activated one or more light-emitting elements transmits through at least one partial area of the transmissive diffraction structures.

Security element and security document

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, between the polymer layers a component being arranged, comprising the following steps: a) the component is arranged on the first polymer layer or placed in a depression of the first polymer layer, b) the first polymer layer is coated on the side, on which or in which the component is arranged, at least in the region of the component with a liquid preparation comprising a solvent or a mixture of solvents and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, c) optionally a drying step is made after step b), d) after step b) or step c), the second polymer layer is placed on the first polymer layer, covering the component, e) the first polymer layer and the second polymer layer are laminated with each other under pressure, at a temperature from 120&#xb0; C. to 180&#xb0; C. and for a defined time.
