Abstract
A secure product, and a production method, comprising a first reflective layer, a second layer and a third layer including readable information, the first layer being enclosed between the second and the third layers, in which the first and second layers are transparent, at least a first part of the internal surface of the second layer comprises a diffusing microstructure, and the diffusing microstructure is positioned so as to cover a predetermined part of the readable information.
Claims8
A secure product comprising a first layer, a second layer and a third layer, the first layer being enclosed between the second and the third layers, wherein:
- the first and second layers are transparent,
- the first layer is reflective and at least partially reflects light incoming toward a side of the first layer that is in contact with the second layer,
- the third layer includes a plurality of zones comprising a photo zone and a machine-readable zone, the machine-readable zone including readable information,
- at least a first part of an interface between the first layer and the second layer comprises an optically diffusing microstructure,
- the optically diffusing microstructure is positioned so as to cover a predetermined part of the readable information,
- wherein a second part of the interface between the first layer and the second layer comprises an optically diffractive microstructure that forms at least one security element, and
- the readable information is readable by a machine through the first and second layers.
