HYBRID SECURITY DEVICE FOR SECURITY DOCUMENT OR TOKEN |
| 摘要 |
A hybrid security device for security documents and the like, with the microstructure for a first optically variable device (OVD) and the microstructure for a second OVD mutually interlace or interspersed. The first microstructure has a height profile that differs from that of the second microstructure by more than 0.5 microns. Suitable fabrication processes for the hybrid security device are also disclosed. |

1. A hybrid security device for security documents and tokens, a hybrid security device comprising:
a substrate; a first microstructure for a first optically variable device (OVD) supported on the substrate in a first region; and, a second microstructure for a second OVD supported on the substrate in a second region; wherein the first and second regions are mutually interlaced or interspersed in at least one area; and the first microstructure has a height profile that differs from that of the second microstructure by more than 0.5 microns. |
