Abstract (en)
[origin: WO2004009373A1] The invention relates to a security feature for a security document, whereby the authenticity can be determined by irradiation with electromagnetic radiation (13, 18) in a spectral range outside that of the visible region. According to the invention, a simple production of security features with strong in/out effects on injection of linear polarised light and/or on observation by means of a rotating polarization filter can be achieved, whereby the security feature comprises a printing (4, 8, 9) or a coating which converts the injected electromagnetic radiation (13, 18) into visible light (15, 21), whereby said printing (4, 8, 9) is at least indirectly covered by means of a polarisation film (2, 6, 7).
