| 摘要 |
The present invention relates to a security structure (1) observable from at least one face (15), the structure (1) comprising: - a network of elementary patterns (5) made from a polymeric material (9), the elementary patterns having a unitary dimension (D) of at least 75 micrometers, that network defining a non-planar surface, - in a first area (20) of said network, a reflective layer (19) that is at least partially visible from the observation face (15), that reflective layer defining a reflective surface following the relief of said network, - in a second area (21) of said network, different from the first, at least one recess (24) formed in the reflective layer (19) and/or one element observable from the observation face (15), said observable element having a surface situated on the side of the observation face (15), which follows the relief of said network, that surface having a different appearance from that of the reflective surface. |
