摘要:
Security element (1, 1', 1'', 1''', 1'''') for the identification of a security document (100), in particular a banknote, a valuable paper or a paper document, comprising at least one electrically controllable display element (16) and at least one piezoelectric energy source (Ia) which controls the at least one display element. The security element is formed by a flexible multilayered film body comprising the at least one electrically controllable display element containing a display layer (5) having liquid crystals that can be oriented in an electric field, and comprising the at least one piezoelectric energy source which controls the at least one display element and has at least one layer (4) composed of piezoelectric material, wherein the security element has a thickness of at most 70 μm in the direction perpendicular to the plane of the film body.

摘要:
The invention relates to a method for producing a multilayer body, having the following steps: a) providing a support layer on which at least one lighting means, in particular an LED, is arranged; b) providing a decorative layer; and c) injecting a plastic layer onto the support layer and/or the decorative layer in an injection mold. The invention further relates to a multilayer body produced using such a method.
摘要:
The invention concerns a multi-layer flexible film body (6), in particular a label film or packaging film as well as a goods identification system and uses of such a film body. The film body (6) has a carrier layer and a decorative layer system (11) which provides optically recognisable information. A plurality of layers of the decorative layer system form an electronically controlled display element (65), by the activation of which the optically recognisable information becomes visible.

The invention relates to a multilayer body (1, 1', 2, 3, 4, 5) with an optically active first system of layers (10), whereby the first system of layers (10) is an optically variable element (OVD) with a structural layer, inside of which a diffraction grating is shaped, and the optical activity of the first system of layers (10) can be influenced by an electrically controllable second system of layers (20, 20', 40, 50, 60).
