description Aqueous coating compositions containing - one or more film-forming, water-dilutable or water-soluble epoxy resins having an epoxide equivalent weight of from 100 to 10,000, - one or more water-dilutable or water-soluble polyamines containing at least 2 primary and/or secondary amino groups in the molecule and having an equivalent weight of from 50 to 500, - optionally pigments, fillers and/or other assistants which are conventional in paint technology, - where the ratio between the reactive hydrogen atoms of the polyamines and the epoxide groups of the epoxy resins is from 0.7:1 to 1.5:1, and from 5 to 80 % by weight of one or more water-dilutable or water-soluble polyurethane resins having a number average molecular weight (Mn) of from 500 to 500,000 based on the sum of the solid weights of epoxy resin and polyamine.
