The invention relates to a metal-chelate of copper (II) with aryl amide of benzimidazole-2-carbothioic acid of general formula (1) (1) where R1 = R2 = H, R3 = CH3; R1 = R2 = H, R3 = CH3O; R1 = R2 = H, R3 = C2H5O; R1 = R2 = H, R3 = Br; R1 = R2 = H, R3 = Cl; R1 = R2 = H, R3 = F; R1 = CH3, R2 = R3 = H; R1 = CH3O, R2 = R3 = H; R1 = R3 = H, R2 = Br; R1 = R3 = CH3, R2 = H ; R1 = Br, R2 = H, R3 = CH3, as modifying admixture to aromatic polyamides. The invention also relates to the composition for dry lubricant coating based on aromatic polyamide which contains graphite and metal-chelate of copper (II) with benzimidazole-2-carbothioic acid aryl amide of general formula (1 ) as modifying admixture.
