Abstract (en)
[origin: WO2017103252A1] The invention relates particularly to a security element comprising a support (1) on which there is at least one print (2; 2'; 2"; 3), including a first print (2) which is invisible to visible light but revealed under a first wavelength range (λ1) outside the visible light spectrum, and a second print (3) which is invisible to visible light but revealed under a second wavelength range (λ2) outside the visible light spectrum, said first and second prints (2, 3) extending in regions which partially cover each other, thereby forming at least one covering region (4), characterised in that it comprises hidden information (IC) formed by said at least one covering region (4), hidden information (IC) revealed under a stroboscopic lighting that alternates lighting under two wavelength ranges corresponding respectively to said first and second wavelength ranges (λ1 and λ2).
