    • The invention relates to aqueous eletrocoating �sic! compositions containing cathodically depositable synthetic resins, which electrocoating compositions are characterized in that they contain polymer microparticles which have a particle size of 0.01 to 10 .mu.m and are preparable by reacting (a) a polyisocyanate or a mixture of polyisocyanates with (b) an organic compound containing not only at least one ethylenically unsaturated double bond but also at least one active hydrogen atom per molecule or a mixture of such organic compounds and (c) an organic compound containing not only at least one active hydrogen atom but also at least one tertiary amino group and/or at least one ketimine group and/or at least one aldimine group per molecule or a mixture of such organic compounds and, if desired, (d) an organic compound other than (b) and (c) containing at least one active hydrogen atom per molecule or a mixture of such organic compounds. The reaction product thus obtained is dispersed in water and subjected to free radical polymerization, with at least 5 percent of the tertiary and/or primary amino groups present in the reaction product being neutralized with a Bronsted acid before, during or after dispersion.
