    • The invention relates to water-dispersible binders which are intended for cationic electropaints and are based on reaction products which are formed from modified epoxy resins and primary and/or secondary amines and which can, if desired, also contain crosslinking agents, pigments, flow-control agents and other customary auxiliaries. The reaction products have been prepared by reacting(A) Low molecular weight epoxy resins which contain aromatic groups and have an epoxide equivalent weight of less than 375 with(B) aliphatic and/or alicyclic polyfunctional alcohols or carboxylic acids having a molecular weight of less than 350 by addition to the epoxy group in such a way that the reaction products contain 10-45% of aromatic groups, calculated as phenylene group, and reacting the reaction products of A and B with(C) if desired up to 60% by weight, relative to total binder, of polyfunctional alcohols, carboxylic acids and/or SH compounds having a molecular weight of 300-5,000, the molar ratios of (A), (B) and, if desired, (C) being chosen in such a way that the resulting intermediate product has terminal epoxy groups,(D) by reacting the intermediate product by the addition of a phenolic hydroxyl group of a monophenol and/or diphenol to the epoxy groups, the monophenol or diphenol having as a substituent on the aromatic ring(s) at least one grouping of the general formula ##STR1## in which R.sup.1 and R.sup.2 are identical to or different from one another and represent hydrogen or a methyl group, and by adding a primary and/or secondary amine before or after the reaction of the phenolic hydroxyl groups with the epoxy groups, to at least some of the double bonds of the grouping of the formula (I).

    • Polyadducts, free from epoxide groups, are obtained from ammonia and epoxide compounds by reacting 1 mole of ammonia with from 1.2 to 2.0 equivalents of epoxide, so that if diepoxide compounds are used products of the general formula (I) ##STR1## are obtained, while if triepoxides and/or tetraepoxide compounds are used, by themselves, or together with diepoxide compounds, products of the general formula II ##STR2## are produced; in these formulae, the E.sup.1 's are identical or different hydroxyl-containing divalent radicals and the E.sup.2 's are identical or different hydroxyl-containing trivalent or tetravalent radicals, resulting from the opening of the oxirane rings of epoxide compounds containing two, three or four epoxide groups in the molecule, n.sup.1, n.sup.3 and n.sup.5 are from 0 to 3, n.sup.2 and n.sup.4 are from 1 to 3 and X is 0 or 1, and one or more of the divalent radicals E.sup.1 in the general formula (II) may or may not be replaced by polyvalent radicals E.sup.2.The novel polyadducts can be modified by reaction with aldehydes, ketones, monoepoxide compounds, carboxylic acids, carboxylic acid esters or isocyanates, or by protonation with an acid, and may be used, for example, for the cathodic electrocoating of metallic articles.
