| 摘要 |
The invention relates to an object of value (15) for example a credit card, bank note or form of identification. The object of value (15) has a carrier layer (1), at least one first layer (21) that contains a moire pattern and at least one second layer (31, 33) comprising at least one moire analyser for the moire pattern of the first layer (21). Said second layer is located above or below the first layer in a fixed position in relation to the first layer, in such a way that at least sections of the moire pattern of the first layer (21) and the moire analyser of the second layer (31, 33) are permanently optically superimposed, thus generating a permanent moire image. ® KIPO & WIPO 2007 |
