Abstract
The invention concerns an object of value (15), for example a credit card, banknote or identity card. The object of value (15) has a carrier layer (1), at least one first layer (21) containing a moiré pattern and at least one second layer (31, 33) containing a moiré analyser for the moiré pattern of the first layer (21). That second layer is arranged above or beneath the first layer in a fixed position relative to the first layer in such a way that the moiré pattern of the first layer (21) and the moiré analyser of the second layer (31, 33) are permanently optically superimposed at least in region-wise fashion, whereby a permanent moiré image is generated.

An object of value, for example a credit card, a banknote or an identity card, comprising:
- a carrier layer,
- at least one optical security element which is disposed on the carrier layer and which has a first layer containing a moiré pattern, and
- a second layer which contains a moiré analyzer for the moiré pattern of the first layer and which is arranged above or below the first layer in a fixed position relative to the first layer in such a way that the moiré pattern of the first layer and the moiré analyzer of the second layer are permanently optically superimposed at least in region-wise manner, whereby a moiré image is generated.
An object of value, for example a credit card, a banknote or an identity card, comprising:
- a carrier layer,
- at least one optical security element which is disposed on the carrier layer and which has a first layer containing a moiré pattern, and
- two or more secondary layers which each contain a respective moiré analyzer for the moiré pattern of the first layer, and a first secondary layer is arranged on the same side of the carrier layer as the first layer and a second secondary layer is arranged on the opposite side of the carrier layer so that a first moiré image is visible when viewed in transmitted light and a second moiré image is visible when viewed in incident light.
