Abstract (en)
The present invention refers to an anticounterfeit multilayer device (1) comprising:- a shift color layer (2) comprising one or more photonic crystals;- a holographic layer (3) comprising a holographic structure (4) occupying all the holographic layer (3) or partially occupying the holographic layer (3) so that the holographic layer (3) comprises one or more portions (5) devoid of the holographic structure (4);- a reflective layer (6);wherein the shift color layer (2) overlaps the holographic layer (3) and the holographic layer (3) overlaps the reflective layer (6).
