Electrodeposition coating materials and method of coating electrically

Epoxy resins for preparing water-dispersible binders for cathodic electrodeposition coating materials, the epoxy resin being preparable by reacting a) polyepoxides having at least one glycidyl group per molecule b) and, optionally, up to 60% by weight, based on the overall epoxy resin reaction product, of aliphatic and/or alicyclic hydroxy compounds having preferably two or on average less than two hydroxyl groups per molecule and a molecular weight of less than 9000 g/mol, c) in the presence of a catalyst consisting of neutral metal salts, such as alkali metal salts and alkaline earth metal salts, zinc salts and nickel salts of tetrafluoroboric, tetrachloroboric, hexafluoro- antimonic,hexachloroantimonic,hexafluorophosphoric, perchlorate and periodic acid, and d) adding a deactivating agent which prevents the epoxy groups reacting further or effectively reduces the rate of such reaction as soon as the phenolic hydroxyl groups have already substantially reacted and at least 0.6% by weight of epoxy groups are still present, based on the overall weight of the epoxy resin reaction product.
