 new patent  Security element

The invention relates to a security element (1), a security document (2) with at least one security element (1), a transfer foil (3) with at least one security element (1) as well as a method for producing a security element (1), wherein the security element has at least one layer (11) that is electrically alterable in its optical effect. It is here provided that the at least one layer (11) that is electrically alterable in its optical effect has liquid crystals (12) that can be oriented in an electric field, wherein the at least one layer (11) that is electrically alterable in its optical effect has rod-shaped dye molecules (13), and the orientations of the longitudinal axes (14) of the rod-shaped dye molecules (13) are alterable depending on the orientations of the longitudinal axes (16) of the spatially adjacent liquid crystals (12) that can be oriented in the electric field, and/or wherein the liquid crystals (12) that can be oriented in the electric field are formed in such a way that the liquid crystals (12) that can be oriented in the electric field simultaneously act as dye molecules.. ...

Multi-layered body, and security document

A multilayer body with a functional layer which includes an antenna element as well as with an optical security element which includes at least one electrically conductive partial region which is galvanically connected to the antenna element. A security document with such a multilayer body, as well as a method for the authentication thereof.. ... Ovd Kinegram Ag

Method for producing security elements, and security elements

A method for producing security elements, security elements, a security document with at least one security element as well as a transfer film with at least one security element wherein a three-dimensional object is recorded and a surface profile of the three-dimensional object, described by a function f(x,y), is determined, wherein the function f(x,y) describes the distance between the surface profile and a two-dimensional reference surface spanned by co-ordinate axes x and y at the co-ordinate points x and y. A first microstructure is determined in such a way that the structure height of the first microstructure is limited to a predetermined value smaller than the maximum distance between the surface profile and the two-dimensional reference surface, and the first microstructure provides an observer with a first optical perception which corresponds to the surface profile of the three-dimensional object described by the function f(x,y).. ...
