The base material of the composition is selected from the group comprising polyurethanes, resins, adhesives, sealants, epoxy coatings, two-part estapol coatings, one-part acrylate base coatings and one-part water based coatings. The composition further comprises a fluorescent marker, diluent such as ethanol or a low boiling hydrocarbon. A method for the marking and identification of assets using a composition comprising two or more encoding compounds selected from the group comprising metal compounds, rare earth compounds, a zirconium compound and a hafnium compound, oxides, inorganic compounds, organic compounds, organometallic compounds or acetylacetonate hydrates.
