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.

Laser-personalizable security articles include multi-layer security documents. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser imagable layer. When imaged, a personalized second composite three dimensional image is created on or in the imagable layer.

The objective of the present invention is to effectively prevent fraud, theft, and the like occurring with respect to a medium manufactured from a source material. This medium is a medium that is cut into a prescribed shape from a source material on which an identifier capable of specifying a location and capable of being read by a reading device is attached at a corresponding location. The prescribed location on the medium is specified as an authentication location enabling recognition of the medium, and at least a portion of the identifier capable of specifying the prescribed location is set as an identifier of the medium.

The invention concerns a film element having a replication layer (43), wherein an optically active surface structure (27) is shaped in a first surface of the replication layer. The surface structure is formed in at least a first region of the film element (35) by a first diffractive surface relief (46) comprising a plurality of successive elements following a first envelope curve (47), wherein the elements respectively comprise an element surface (48) arranged substantially parallel to a base surface and at least one flank adjoining the adjacent element surface or surfaces, the element surfaces (48) of adjacent elements are spaced in a direction perpendicular to the base plane, with a first optical spacing or a plurality of the first optical spacing, wherein the first optical spacing is between 150 nm and 800 nm, preferably between 150 nm and 400 nm. The first envelope curve (47) has a spatial frequency of between 100 L/mm and 2000 L/mm and an optical depth of more than 450 nm and the relief shape and the spatial frequency of the envelope curve (47) are so selected that the incident light is diffracted into one or more first directions to represent a first item of information, the color value of which is further determined by the first optical spacing.

Disclosure relates to the field of graphical elements and is directed to a device for producing an optical effect layer (OEL). Disclosure provides an optical effect that is easy to detect as such and exhibits a viewing-angle dependent apparent motion of image features over an extended length if the viewing angle with respect to the OEL changes. OEL includes a binder material being at least partially transparent and a plurality of particles dispersed within the layer. Each particle has a non-isotropic reflectivity and may be magnetic or magnetizable. Orientation of the particles forms an orientation pattern extending over a length within an extended surface of the OEL, such that the local average of an angle between (i) a straight line along an observed longest dimension within the corresponding cross-section shape, and (ii) said first direction x varies according to a function () of a position (P) along said first direction.
