    • 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 formlula (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.

    • 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. They contain as reaction products those which have been prepared by reacting(A) low molecular weight epoxy resins which contain epoxy compound aromatic groups and have an epoxide equivalent weight of less than 375 with(B) aliphatic and/or alicyclic polyfunctional alcohols having hydroxyl groups or carboxylic acids having carboxylic groups and both having a molecular weight of less than 350 and addition of the hydroxyl groups and carboxylic groups to the epoxy groups of (A) in such a way that the reaction products of (A) and (B) contain 10-45% of aromatic groups, calculated as the phenylene group, and have terminal epoxy groups.(C) reacting the terminal epoxy groups of the reaction products of (A) and (B), and thus chain-lengthening, with the phenolic hydroxyl groups of a mononuclear or polynuclear phenol which has at least two phenolic hydroxyl groups and at east one .alpha.,.beta.-olefinically unsaturated amidomethyl group of the following general formula ##STR1## as a substituent on the aromatic rings(s) and 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(D) reacting the intermediate procuct obtained from (A), (B) and (C) with a primary or secondary amine or an ammonium salt.
