The invention relates to a thin optical security element comprising a reflective or refractive light-redirecting surface having a relief pattern operable to redirect incident light from a light source and form a projected image on a projection surface, the projected image comprising a caustic pattern reproducing a reference pattern that is easily visually recognizable by a person. The invention also relates to a method for designing a relief pattern of a light-redirecting surface of a thin optical security element.

An optical storage phosphor, a method for checking an authenticity feature, and an apparatus for carrying out a method, relate to an authenticity feature and to a value document. An inorganic optical storage phosphor is provided having a garnet structure and predetermined composition.

A security inlay having optically recognizable characters for an identity document comprises a first transparent layer and a second transparent layer. A color coating is situated on the first transparent layer. Furthermore, a first UV color coating, which reflects at least UV light at least in a first wavelength range, is situated on the first layer and/or on the color coating. The first and second transparent layers are connected to one another. A first portion of the optically recognizable characters is formed by blackened sections in at least one of the layers. A second portion of the optically recognizable characters is formed by the color coating. A third portion of the optically recognizable characters is formed by the UV color coating. The first and the second portions of the optically recognizable characters reflect visible light. The third portion of the optically recognizable characters reflects UV light.

A laminate includes a recording layer, a translucent front covering layer and a security foil laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is ⅕ or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer having a relief surface and a protective layer covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.
