摘要:
The invention relates to a system (100, 200, 300, 400, 500, 600) for producing a security element (4), in particular a vignette for a windshield pane (6) of a transportation means. The security element comprises a support element (3) with a first and a second surface, wherein a first sub-element (1) of the security element (4) is arranged in a first region (31) of the first surface, and a second sub-element (2) of the security element (4) is arranged in a second region (32) of the first surface, said second region being separated from the first region (31) by a folding edge (33). The sub-elements (1, 2) can be brought into a stacked arrangement by folding the support element (3) along the folding edge (33) and can be adhered by means of an adhesive (25) arranged on the second sub-element (2) face facing away from the support element (3). An individualizing feature (14) can be applied onto a first (1) and/or second sub-element (2) face facing away from the support element (3). The invention further relates to a method for producing a security element (4) using such a system (100, 200, 300, 400, 500, 600) and to a security element (4) obtained using said method.

The invention relates to a layered structure (10) comprising the following layers: a) a first substrate layer (2), wherein the first substrate layer (2) has a first surface (4) and a second surface (6) and is configured as a dielectric; b) a first electrically conductive layer (8) which overlaps at least in part the first substrate layer (2) at least on the first surface (4) of the first substrate layer (2), wherein the first electrically conductive layer (8) comprises an electrically conductive polymer, wherein the first electrically conductive layer (8) has at least one first part region (18) and at least one further part region (20), wherein the at least one first part region (18) has a higher bonding strength to the substrate layer (2) than to the at least one further part region (20).
摘要:
The invention relates to a security composite body (100) and a method for producing such a security composite body (100), said method comprising the following steps: producing a composite body, forming a surface relief structure (75) on an outer surface of the composite body, introducing an optically verifiable feature (61) into the composite body, wherein the surface relief structure (75) and the feature are formed in exact alignment with each other, wherein the composite body is produced in such a way that, in the interior, a boundary layer between a first plastic material having a first index of refraction n 1 and a second plastic material (11) having a second index of refraction n 2 different from the first index of refraction n 1 is structured with a boundary layer relief structure (5) deviating from a flat surface and is oriented in exact alignment with the feature and the surface relief structure (75), so that a verification of the feature (61) can be verified by means of an optical structure formed from a combination of the surface relief structure (75) and the boundary layer relief structure (5).
