    • The invention relates to water-dispersible binders for cationic electrocoating finishes, which are obtained by reaction of(A) epoxy resins containing low molecular weight aromatic groups and having an epoxide equivalent weight of less than 375 with(B) aliphatic and/or alicyclic polyfunctional alcohols or carboxylic acids having a number average molecular weight of less than 350, further reaction of the product of (A) and (B) with(C) a polyfunctional alcohol having a molecular weight of more than 350, addition at the epoxide groups taking place so that the reaction products of (A) and (B) contain an amount of aromatic groups of from 10 to 45% by weight, calculated as phenylene groups, and further modification of the resulting intermediate with(D) primary and/or secondary amines or ammonium salts in order to achieve the required water-dispersibility. The binders contain, as component (C), 5 to 40% by weight, based on the total binder, of a linear polyalkylene ether diol which has on average one terminal primary and one terminal secondary hydroxyl group per molecule and corresponds to the general formula ##STR1## in which n denotes 1 to 4, preferably 1, and m denotes 4 to 35, preferably 5 to 20.

    • 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.
