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 analyzer 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 analyzer of the second layer (31, 33) are permanently optically superimposed at least in region-wise fashion, whereby a permanent moiré image is generated.
