Abstract (en)
[origin: WO2004101890A1] The invention relates to a flat dual security mark comprising two different security elements, one of which can be checked in the visible spectral region and the other in the ultraviolet spectral region of the light. Said security mark comprises plate-type effect pigments and luminescent pigments in such a low concentration that the latter can be recognised as individual particles with the naked eye under the action of UV light. The invention also relates to a method for producing said security mark and to the use of the same.
