Abstract: A process for producing a multilayer body (100) is specified. In this process, an HRI layer (7) made of a material having a high refractive index is applied to at least part of the surface area of a substrate (4). At least one partial region (10) of the HRI layer (7) is then physically removed from the substrate (4) again by treatment with an alkaline solution. Additionally specified is a multilayer body (100) that can be obtained by such a process.

Abstract: A method for verifying a security document by means of a reading device wherein first transmission and/or reflection properties of a first region of the security document are detected in a first spectral range by the reading device and a first data set specifying these properties is generated therefrom, wherein the first region at least in some regions overlaps an optical security element arranged on the security document or embedded in the security document and wherein second transmission and/or reflection properties of the first region of the security document are detected in a second spectral range by the reading device and a second data set specifying these properties is generated therefrom, wherein the first spectral range differs from the second spectral range, and wherein, the authenticity of the security document and/or of the security element is checked on the basis of at least the first data set and the second data set.

Abstract: The invention relates to a transfer film (1), in particular hot-stamping film, the use of a transfer film (1), a film, a security document (2), and a method for producing a transfer film (1). Here, it is provided that the transfer film (1) comprises a transfer layer (20) detachably arranged on a carrier layer (10). The transfer layer (20) further has at least one first color layer (30) and the at least one first color layer (30) comprises at least one binder and at least first pigments, the color appearance of which changes depending on the observation angle.
