A synthetic resin is in the form of a metal complex compound. The resin is the reaction product of: (a) Mannich bases which are free from epoxide groups; with (b) epoxide resins; wherein aliphatic hydroxyl groups originating from (a), (b), or a mixture thereof, are at least partially converted into urethane groups by reaction with partially blocked isocyanate, said Mannich bases (a) formed from components selected from: (a1) condensed phenols which are free from ether groups and contain at least two aromatic rings and at least two phenolic hydroxyl groups; (a2) condensed phenols which contain ether groups and contain at least two aromatic rings and at least two phenolic hydroxyl groups; (a5) formaldehyde or compounds which split off formaldehyde; (a3) secondary amines having at least one hydroxyalkyl group; and (a4) dialkylamines or dialkoxyalkylamines which do not contain free hydroxyl groups; or from the components: (a1) and (a2) with (a5) and (a3); (a1) with (a5) and (a3); (a2) with (a5) and (a3); (a1) with (a5), (a3), and (a4); or (a2) with (a5), (a3), and (a4); and copper bound with the reaction product to form the metal complex compound.
