    • A synthetic resin which carries basic nitrogen groups and is water-dilutable by protonation with an acid, containing(A) a chain-extended, amine-modified epoxy resin obtainable by reacting(a.sub.1) an epoxy resin having an average molecular weight M.sub.n of from 300 to 6,000 and on average from 1.5 to 3.0 epoxy groups per molecule with(a.sub.2) a diketimine of a diprimary diamine, which diprimary diamine contains no further groups reactive with epoxy groups under mild conditions and(B) an amino-modified epoxy resin obtainable by reactingb.sub.1) an epoxy resin having an average molecular weight M.sub.n of from 800 to 6,000 and on average from 1.5 to 3.0 epoxy groups per molecule with(b.sub.2) a secondary amine or a secondary-tertiary diamine, a ketimine of a primary monoamine or a ketimine of a primary/tertiary diamine or a mixture of these (b.sub.2) components, with the proviso that (A) and (B) are different.
