Reaction product salts of epoxides, polyalkylenepoly-aminoamides, fatty amines and fatty acids or fatty acid esters, halides, isocyanates or ketene dimers

A reaction product salt of (A) 1.0 epoxy group equivalent of a diglycidyl ether of 2,2-bis-(4'-hydroxyphenyl)-propane, (B) 0.2 to 1.0 amino group equivalent of a polyalkylenepolyaminoamide of (B') a polymerised, unsaturated fatty acid which is derived from fatty acids having 12 to 24 carbon atoms and (B") an aliphatic polyalkylenepolyamine having 4 to 12 carbon atoms, (C) 0.3 to 0.6 amino group equivalent of at least one primary fatty amine having 12 to 24 carbon atoms, (D) 0 to 1.0 mol, per epoxy group equivalent of component (A), of an epihalogenohydrin and (E) 0.01 to 0.5 mol, per mol of amino group equivalent of components (B) and (C), of at least one saturated or unsaturated fatty acid having 12 to 24 carbon atoms, or an alkyl ester, having 1 to 4 carbon atoms in the alkyl radical, isocyanate, halide or ketene dimer thereof, the reaction being carried out in the presence of an inert, organic solvent or in a melt at temperatures up to 110.degree. C., and it being ensured, by adding an acid, at the latest when the reactions have ended, that a sample of the reaction mixture diluted with water to 10 to 40 percent by weight has a pH value of 2 to 8, a salt being formed.
