FIELD: applied nuclear physics. SUBSTANCE: composition contains organic and inorganic luminophors, number of ingredients being at least two and their weight proportion chosen arbitrarily. Luminescence spectrum of each ingredient differ from each other within the region of spectrum from 300 to 1200 nm. Glowing kinetics after impulse excitation of ingredients is different, decay time from 10-6 to 10 s, and conversion efficiency 1 to 40%. Ingredients are also characterized by different dependencies of luminescence on intensity of additional IR irradiation. Ingredients are mixed with varnishes, enamels, or epoxy resins. EFFECT: considerably reduced falsification probability. 2 cl
