Abstract (en)
[origin: CA2941531A1] The invention relates to a document (15) comprising: at least one first image (5) comprising at least one photoluminescent pigment that is invisible under illumination in visible light and visible under illumination by at least one first source (20) of non-visible light emitting in the short ultraviolet domain, characterised in that it furthermore comprises: at least one second image comprising at least one photoluminescent pigment that is invisible under illumination in visible light and visible under illumination by at least one second source of nonvisible light emitting in the long ultraviolet domain; and at least one layer, called a filtering layer, placed facing said second image and comprising at least one material, called a filtering material, suitable for allowing the wavelengths emitted by said first source of non-visible light to be filtered without preventing the first image from being seen under illumination by the first light source.
