Embodiment Construction

[0025] figure 1 A data carrier 1 according to the invention is shown which has different security elements. A security element is an element that increases the forgery protection of the data carrier. For example, an image 3 of the data carrier holder and printed data 4 for the data carrier holder are applied to the data carrier 1, preferably by means of embossing or by means of laser writing (Laserbeschriftung) applied to the laser-active layer or laser of the data carrier in the sensitive layer. The data carrier can contain other electronic components, such as RFID transponders, chip modules or antennas for dual interface modules. The data carrier also has a region 5 in which the volume hologram elements are arranged. Area 5 can partially or completely cover the data carrier. Such volume holograms can reproduce images, patterns, information made of letters or numbers, which can be analyzed both visually and by machine. Visual analysis is performed by the human eye, which...

Abstract

The invention relates to a data support (1) with a core layer (15) and at least one adjacent layer (14a), laminated to the core layer and a corresponding production method, said core layer being embodied from a holographic data store in the form of a volume hologram (5). The surface (141) facing the core layer, on the layer directly adjacent to the core layer, has a roughness (19), before lamination to the core layer, which affects the wavelength shift of the image reconstructed by the volume hologram.

Description

technical field [0001] The invention relates to a data carrier having a core layer and at least one adjacent layer superimposed on the core layer, wherein the core layer is formed by a holographic data store in the form of a volume hologram. Furthermore, the invention relates to a method for producing a data carrier having a core layer and at least one layer adjacent to the core layer, wherein the core layer consists of a holographic data store in the form of a volume hologram, the At least one layer adjacent to the core layer is laminated on the core layer. Background technique [0002] In the context of the invention, data carriers are chip cards, smart cards, personal documents, certificates, driver's licenses, cheques, notes and other securities and insurance documents, as well as data carriers. [0003] A data carrier according to a given type and a method for producing such a data carrier are described in document DE 3856284 T2. For transfer to a document of value, t...
