A B S T R A C T An aqueous cathodic electrodeposition lacquer coating composition containing (A) from 95 to 5% by weight, based on the synthetic resin binder as a whole, of one or more polycondensation, polymerization and/or polyaddition resins, the resin or, where several resins are present, the mixture of resins a) having a number average molecular weight (?) of from 700 to 10,000, b) containing from 0 to 21.7 x 1023 lateral or terminal double bonds per 1000 g, corresponding to a hydrogenation iodine number of from 0 to 90, c) containing primary hydroxyl groups corresponding to a hydroxyl number of from 15 to 300 and d) containing tertiary amino groups corresponding to an amine number of from 30 to 150, (B) from 5 to 95% by weight, based on the synthetic resin binder as a whole, of polymerization, polycondensation and/or polyaddition resins having a number average molecular weight (Mn) of from 170 to 10,000 and con- taining on average at least 2 terminal or lateral ethylenic double bonds per molecule and less than 1 terminal ester group capable of transesterification on baking per molecule, and its use for cathodic deposition from a lacquer bath onto electrically conductive surfaces.
