Value document and method for checking the presence of the same

A value document comprising particulate agglomerates respectively containing at least two different homogeneous phases, wherein the first homogeneous phase is based on a first non-luminescent substance detectable by a spectroscopic method and the second homogeneous phase is based on a second non-luminescent substance detectable by a spectroscopic method, and wherein upon an evaluation of measurement values that are obtainable by a location-specific measurement, carried out at different locations of the value document, of the first measurement-signal intensity caused by the first substance and underlying the spectroscopic method and the second measurement-signal intensity caused by the second substance and underlying the spectroscopic method, there is a statistical correlation between the first measurement-signal intensities and the second measurement-signal intensities;

• wherein the spectroscopic method suitable for the detectability of the first non-luminescent substance and the spectroscopic method suitable for the detectability of the second non-luminescent substance are identical, wherein preferably the exciting electromagnetic radiation of the spectroscopic method is radio-wave, microwave, terahertz or infrared radiation;
• wherein the non-luminescent substance of the first homogeneous phase and the non-luminescent substance of the second homogeneous phase are chosen from the following five kinds of substance, namely, a substance detectable by nuclear magnetic resonance spectroscopy, a substance detectable by electron spin resonance spectroscopy, a substance detectable by nuclear quadrupole resonance spectroscopy, a substance detectable by SER (surface-enhanced Raman) spectroscopy and a substance detectable by SEIRA (surface-enhanced infrared absorption) spectroscopy, on the condition that the kind of non-luminescent substance of the first homogeneous phase is identical with the kind of non-luminescent substance of the second homogeneous phase.
