The invention relates to water-dispersible binders for cationic electrocoating finishes, which binders are reaction products of (A) low molecular weight epoxide resins containing aromatic groups and having an epoxide equivalent weight of below 375, (B) aliphatic and/or alicyclic polyfunctional alcohols and/or carboxylic acids having a molecular weight of below 350, (C) if appropriate up to 60% by weight, relative to the total binder, of polyfunctional alcohols, carboxylic acids and/or SH compounds having a molecular weight of 500-5,000 and (D) primary, secondary and/or tertiary amines and/or salts thereof or a sulfide/acid mixture or a phosphine/acid mixture, the reaction product of A and B containing 10-45% of aromatic groups, calculated as the phenylene group. By means of the binders, a higher layer thickness is obtained in electrocoating.

The invention relates to aqueous electrocoating baths containing synthetic resins capable of deposition on the cathode. The electrocoating baths according to the invention are characterized in that they contain a homopolymer or copolymer of an alkyl vinyl ether of the general formula CH.sub.2 .dbd.CH--O--R wherein R represents an alkyl radical having 2 to 4 C atoms.

Aqueous electrocoating baths containing synthetic resins capable of

The invention relates to water-dilutable binders for cationic electrocoating finishes, the said binders containing latent primary amino groups. In order to prepare the binders, an epoxy resin is reacted with a polyamine, which in addition to a sterically hindered primary amino group also contains at least one primary amino group blocked by reaction with a ketone or aldehyde, and, if appropriate, further primary or secondary amines.

The invention relates to water-dilutable binders for cationic electrocoating finishes. For the preparation of the binders, a di-epoxide compound, together with at least one mono-epoxide compound if desired, is converted by a polyaddition, carried out at 100.degree. to 195.degree. C. and initiated by a monofunctionally reacting initiator carrying either an alcoholic OH group, a phenolic OH group or an SH group, to form an epoxy resin which then subsequently is modified with

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
