| 摘要 |
The invention relates to a value document comprising particulate agglomerates, which each contain at least two different homogeneous phases, wherein the first homogeneous phase is based on a first non-luminescent substance detectable by means of a spectroscopic method and the second homogeneous phase is based on a second non-luminescent substance detectable by means of a spectroscopic method. In an evaluation of measured values which can be obtained by a location-specific measurement, carried out at different locations on the value document, of the first measurement signal intensity caused by the first substance and forming the basis for the spectroscopic method, and of the second measurement signal intensity caused by the second substance and forming the basis for the spectroscopic method, a statistical correlation exists between the first measurement signal-intensities and the second measurement signal intensities. |
