FIELD: adhesive compositions.

SUBSTANCE: invention relates to adhesive compositions used in gluing rubbers based on various rubbers, in attaching rubber compounds based on polar rubbers to a cord rubberized with a rubber compound based on general-purpose rubbers, in the manufacture of multilayer rubber and rubber-cord products in the rubber and tire industries. The adhesive composition contains chloroprene rubber, nitrile butadiene rubber with polyvinyl chloride, zinc oxide, magnesium oxide, rosin, colloidal silicic acid, solvent (nefras and ethyl acetate), quinoxalyl-substituted nitrosopyrazole, such as 3-(3,5- dimethyl-4-nitroso-1H-pyrazol-1-yl)quinoxalin-2(1H)-on, or 3-(3-methyl-4-nitroso-5-phenyl-1H-pyrazol-1-yl)quinoxalin-2(1H)-one, or 3-(4-nitroso-3,5-diphenyl-1H-pyrazol-1-yl)quinoxalin-2(1H)-on.

EFFECT: composition contributes to an increase in the strength of the adhesive joint, expanding the range of its application for a wider range of bonded materials.
