The invention relates to a security feature having a luminescent substance with the general formula AXO.sub.3: Z (I) or B.sub.0.5XO.sub.3: Z (II) or A.sub.1-2yB.sub.yXO.sub.3: Z (III), where A is an alkali metal, B is an alkaline earth metal, X stands for Nb or Ta, Z is the luminescence activator, and y lies between 0 and 0.5. The invention also relates to a security element, a security paper and a value document which is equipped with the security feature according to the invention, and to the use of the luminescent substance with the general formula (I), (II) or (III) as a feature substance for authentication. The luminescent substance is obtained by annealing solid starting materials.

A method for producing a multilayer film, with the steps: a) providing a base body with a carrier ply and a transfer ply, which comprises at least one layer; b) applying an in particular UV-curable adhesive to at least one partial area of the transfer ply of the base body; c) applying a stamping foil which comprises a carrier ply and a transfer ply, with the result that the transfer ply of the stamping foil comes into contact with the transfer ply of the base body coated with adhesive; d) curing the adhesive by UV irradiation; e) removing the carrier ply of the stamping foil.

A security device is provided including a first pattern of elements and a second, overlapping, pattern of elements spaced by a transparent layer, the first and second patterns in combination obstructing the passage of light transmitted to a viewer through the device to a varying degree depending on the viewing position. The first and second patterns of elements are configured such that a first region of the device exhibits a maximum change in the degree of obstruction when the device is tilted relative to the viewer about a first tilt axis, and a second region of the device exhibits a maximum change in the degree of obstruction when the device is tilted relative to the viewer about a second tilt axis which is not parallel to the first tilt axis.

A security device with multiple layers. A substrate provides the backing to a first luminescent layer. An optically variable structure is positioned between the first luminescent layer and a second luminescent layer. Both the first and second luminescent layers emit luminescent radiation when stimulated. When the first layer is stimulated, the optically variable structure filters the emitted luminescent radiation such that the emitted luminescent radiation only escapes the optically variable structure at a predetermined range of emission angles. A user, when viewing the security device from the predetermined range of angles as both layers are stimulated, can see a completed image of a predetermined indicia. When the security device is viewed at angles other than the predetermined range of angles as both layers are stimulated, a user will only see an incomplete image of the predetermined indicia.

The invention relates to a method for producing a multilayer body (100, 200, 300, 400), as well as a multilayer body (100, 200, 300, 400) produced thereby. A single- or multi-layered first decorative ply (3) is applied to a carrier ply with a first (11) and a second (12) side. A metal layer (5) is applied to the side of the first decorative ply (3) facing away from the carrier ply and structured such that the metal layer (5) is provided with a first layer thickness in one or more first zones (8) and is provided with a second layer thickness different from the first layer thickness in one or more second zones (9), wherein in particular the second layer thickness is equal to zero. A single- or multi-layered second decorative ply (7) is applied to the side of the metal layer (5) facing away from the first decorative ply (3) and structured using the metal layer (5) as mask such that the first (3) or second (7) decorative ply is at least partially removed in the first (8) or second (9) zones.
