FIELD: physics.SUBSTANCE: method comprises the introduction of a marking composition containing oligomeric polyester glycols of 1,000 and 2,000 mol. wt. and at least two organic luminescent ingredients with different luminescence spectra, glow kinetics, and luminescence intensity when irradiated with UV and/or IR light, into crude rubber mixture. Luminescent ingredients are selected from α-naphthylamine, coumarin, fluorescein, acridine and salicylic acid in an amount of 0.1 to 2.16 g per 100 g of rubber mixture. The invention provides encoding of information about a rubber product including the manufacturer's coding and the rubber product manufacture date.EFFECT: improving the accuracy of rubber products identification while expanding the range of identification characteristics.4 cl, 5 tbl, 6 ex
