PCT No. PCT/EP86/00302 Sec. 371 Date Jan. 23, 1987 Sec. 102(e) Date Jan. 23, 1987 PCT Filed May 17, 1986 PCT Pub. No. WO86/07082 PCT Pub. Date Dec. 4, 1986.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 DEG to 195 DEG 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 (A) primary and/or secondary amines or their salts and/or the salt of a tertiary amine, a sulfide/acid mixture or a phosphine/acid mixture and with, if desired, (B) a polyfunctional alcohol, a polycarboxylic acid, a polysulfide or a polyphenol.
