Description
' .7712956-7 2 _ Kompositionerna enligt uppfinningen innefattar ett hydrazinsalt av en karboxylsyra innehållande minst en organisk hydrofob grupp med 5 kolatomer eller mer. Den hydrofoba gruppen kan vara en rak, grenad eller cyklisk alifatisk grupp, en aromatisk grupp eller en alkyl- substituerad cyklisk alifatisk eller aromatisk grupp. Den hydrofoba gruppen kan innehålla amino eller amidogrupper. Vidare kan de hydro- foba grupperna vara substituerade med inerta substituenter, det vill säga substituenter vilka ej väsentligt påverkar de hydrofoba egenskaperna eller föreningarnas absorption till metaller. Som exempel på inerta, icke-störande substituenter kan nämnas eter- och estergrupper. '.7712956-7 2 _ The compositions of the invention comprise a hydrazine salt of a carboxylic acid containing at least one organic hydrophobic group with 5 carbon atoms or more. The hydrophobic group may be a straight, branched one or cyclic aliphatic group, an aromatic group or an alkyl group substituted cyclic aliphatic or aromatic group. The hydrophobic the group may contain amino or amido groups. Furthermore, the the foba groups be substituted with inert substituents, that is say substituents which do not significantly affect the hydrophobic properties or the absorption of the compounds into metals.
