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.
Claims13
A multilayer product intended for securing readable information, Comprising:
- a first reflective layer;
- a carrier;
- and
- a second layer enclosed between the first layer and the carrier, wherein:
- the first and the second layers are transparent, and
- at least a first part of the surface of the second layer opposite the carrier comprises a diffusing microstructure.
A secure product 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, wherein:
- 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.
A method for producing a multilayer product intended for securing readable information, the product comprising a first reflective transparent layer, a carrier and a second transparent layer enclosed between the first layer and the carrier, the method comprising:
- the deposition of the second layer onto the carrier;
- the formation of a diffusing microstructure on at least a first part of the surface of the second layer opposite the carrier;
- and
- the deposition of the first layer onto the second layer thus provided with the diffusing microstructure.
