Abstract (en)

A photoluminescent fibre (12) for the incorporation into a security document (4) is proposed, which is characterised in an anisotropic cross-section (9). A particularly pronounced and well observable effect when embedding such security element in a paper or paper-like structure can be achieved due to the anisotropy of the cross-section (9) since such a photoluminescent fibre (12) surprisingly shows the tendency to remain at the surface of a paper and to a line with a long principle axis (11) substantially parallel to the surface (6) of the corresponding document. This is particularly useful and effective if the photoluminescent fibre (12) shows linearly polarised absorption and/or linearly polarised photoluminescence. <IMAGE>
