Abstract
Abstract The invention relates to aqueous coating agents, impregnating agents and adhesives in which the binder is a mixture of from 20 to 97% by weight of a cationic water-dispersible resin and from 3 to 80% by weight of a hydrocarbon resin, and/or a modified hydrocarbon resin, which per se is not water-dispersible. The coating agents, impregnating agents and adhesives may in particular be used for the cathodic electrocoating of metallic articles.
