Synthetic resin

Abstract

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: (a.sub.1) condensed phenols which are free from ether groups and contain at least two aromatic rings and at least two phenolic hydroxyl groups; (a.sub.2) condensed phenols which contain ether groups and contain at least two aromatic rings and at least two phenolic hydroxyl groups; (a.sub.5) formaldehyde or compounds which split off formaldehyde; (a.sub.3) secondary amines having at least one hydroxyalkyl group; and (a.sub.4) dialkylamines or dialkoxyalkylamines which do not contain free hydroxyl groups; or from the components: (a.sub.1) and (a.sub.2) with (a.sub.5) and (a.sub.3); (a.sub.1) with (a.sub.5) and (a.sub.3); (a.sub.2) with (a.sub.5) and (a.sub.3); (a.sub.1) with (a.sub.5), (a.sub.3), and (a.sub.4); or (a.sub.2) with (a.sub.5), (a.sub.3), and (a.sub.4); and copper bound with the reaction product to form the metal complex compound.
