The invention relates to an absorbent medium for improving the overprintability, in particular by inkjet printing, of a security element, in particular an optically variable security element, comprising a binder, at least one pigment and an in particular aqueous solvent. The invention furthermore relates to a transfer film with an absorbent layer made of such an absorbent medium as well as a method for personalizing a security element using such a transfer film.

Absorbent medium, transfer film, security element, and method for personalizing a security element

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

Transfer film and method for producing a transfer film

A system () for producing a security element (), in particular a vignette for a windshield () of a means of transport, is specified. This comprises a carrier element () with a first and a second surface, wherein a first sub-element () of the security element () is arranged in a first area () of the first surface and a second sub-element () of the security element () is arranged in a second area () of the first surface separated from the first area () by a fold edge (). These sub-elements () can be made to overlap with the first sub-element () by folding of the carrier element () along the fold edge () and can be adhered by means of an adhesive () arranged on the side of the second sub-element () facing away from the carrier element (). An individualization feature () can be attached to a side of the first () and/or the second () sub-element facing away from the carrier element (). Furthermore, a method for producing a security element () by means of such a system (), as well as a security element () obtained thereby, is specified.

System and method for producing an individualized security element

A method for the production of a multilayer body, in particular a security element, includes: a) producing a metal layer on a substrate; b) partial demetalization of the metal layer to form a first item of optical information in a first area of the multilayer body; c) applying a partial lacquer layer in a second area of the multilayer body to form a second item of optical information, wherein the partial lacquer layer extends at least partially beyond the metal layer; d) structuring the partial metal layer in the second area using the partial lacquer layer as mask.

Multi-layer body and method for the production thereof

The invention relates to a security document () having a carrier substrate () and at least one first film element () which is fixed to the carrier substrate () and shows a first optically variable effect generated by a diffractive first relief structure, wherein the security document () furthermore has at least one first printing ink layer () which is applied in a region-wise fashion onto the at least one first film element, and at least one second film element (), and to a method for the production, of the security document ().
