Abstract
A compound containing a ligand group and a group of the general formula --NRCOR.sup.1.sub.a X.sub.b CR.sup.2 .dbd.CHCOR.sup.3 is used for treatment of a metal. The ligand group can be a triazole, an imidazole, an indazole, a thiazole, an oxazole, a carbamate, an xanthate or a phthalazine, or derivatives thereof. The compounds can be coated onto a metal surface, for example a copper surface. The metal surface may also be coated, simultaneously or subsequently, with a surface coating composition such as a paint or lacquer or an adhesive. When used with an adhesive, an increase in the adhesive strength is achieved.
