Value document having security marking with varying decay time and method for identifying the security marking
A value document has a security marking in the form of two luminescent substances whose the emission spectra partially overlap in a primary emission range. The emission spectra have a degree of overlap of less than 80% and more than 5%, wherein the luminescent substances have different individual de...

| description | A value document has a security marking in the form of two luminescent substances whose the emission spectra partially overlap in a primary emission range. The emission spectra have a degree of overlap of less than 80% and more than 5%, wherein the luminescent substances have different individual decay times in the primary emission range. The individual decay times of the luminescent substances differ from each other by more than 50% with reference to the shortest individual decay time. |
