Abstract: The invention relates to aqueous electrocoating paints which contain 2 to 10% by weight of an anticorrosive pigment based on zinc silicate in combination with 1 to 15% by weight of a very fine quartz powder or cristobalite powder coated with epoxysilane or aminosilane, the percentages by weight being based on the total solids content of the electrocoating paint and the anticorrosive pigment being preparable by fusing together 35 to 65% by weight of ZnO, 15 to 35% by weight of SiO.sub.2 and 0 to 20% by weight of B.sub.2 O.sub.3 and/or 0 to 20% by weight of WO.sub.3 and/or 0 to 20% by weight of MoO.sub.3 and/or 0 to 20% by weight of SnO.sub.2, the components being fused together using at least one of the cited oxides besides ZnO and SiO.sub.2 in such a manner that the percentages by weight always total 100.
