Abstract of the Disclosure The invention relates to a process for preparing compo- sitions for coating metal substrates or work pieces in an aqueous bath, in which the substrate forms the cathode. In this process 5 - 35% by weight of at least one epoxy resin, 2 - 20% by weight of at least one ketone and/or hydrocarbon resin, 15 - 60% by weight of at least one cationic synthetic resin having functional groups - this compound is a 10 - 50% by weight dispersion or solution -, 5 - 30% by weight of at least one organic cross-linking agent, which is solid at ambient temperature and 0 - 73% by weight of pigments and/or conventional adjuvants are processed together in one or more stages in a grinding apparatus to form a homogeneous coating composition. At least one stage being a wet operation. The composition has a particle size of less than 100 µm, prefer- ably less than 15 µm. The grinding bath is adjusted with water to the solids content required for application. The particles ob- tained by the process are more homogeneous, with the result that, when applied to the object which is to be coated, a uniform layer thickness of the coating is obtained, which shows an increased impact strength.
