Abstract
The present invention is based on a method for marking products using two or more ink formulations, each containing one or more photoluminescent dyes emitting radiation in the range of 380-3000 nm under photon excitation and distinguished by different fluorescence lifetimes, for storing information in serialization and/or track & trace systems and for document security.
