Composition containing one or more lubricants or hydraulic oils based on mineral oil, synthetic oils or mixtures thereof and at least one compound of the formulae I, II or III, <IMAGE> I <IMAGE> II <IMAGE> III <IMAGE> in which R1, R2, R3, R4+L, R5 and R6 independently of one another are C1-C24 alkyl or C1-C24 alkyl which can be substituted by oxo or thio groups, or C3-C24 alkyl which can be interrupted by <IMAGE> -S- and/or -N(R8)- in which R8 is hydrogen or C1-C12 alkyl and which can be substituted by oxo or thionogroups, or C2-C24alkenyl or phenyl or naphthyl which is unsubstituted or substituted by one or two C1-C12 alkyl, C2-C24 carboalkoxy or nitro groups; or are C7-C10 phenylalkyl, and R1, R2, R3 and R4 additionally are hydrogen, or R1 and R2, or R1 and R3 in the event that n is zero, together with the C atoms to which they are attached, form a 5-membered or 6-membered aliphatic ring which can be interrupted by -N(R8)- in which R8 is as defined above, -O- or -S- and/or can be substituted by oxo or thiono groups; or in which R4 and R5, together with the N atom to which they are attached, form a 5-membered or 6-membered aliphatic-heterocyclic ring which, additionally to the N atom, can contain further heteroatoms [N(R8), O or S] and/or can be substituted byoxo or thiono groups, and in which R7 is also C2-C12alkylene which can be interrupted by -N(R8)-, -O- and/or -S- and/or can contain oxo or thiono groups, C6-C15cycloalkylene, C6-C15arylene, carbonyl or thiocarbonyl, or the group -N(R4)-R7-N(R4)- is a piperazine-1,4-diyl radical which can be substituted by one or more methyl groups, and X is also oxygen or sulfur and n is the numbers zero or 1, and also the compounds themselves, provided that they are novel.
