Abstract:
The invention relates to aqueous, cationically stabilized primary dispersions comprising dispersed polymer particles having a Z-average particle diameter of 5 to 500 nm and which are obtainable by emulsion polymerization of at least one olefinically unsaturated monomer (A). The emulsion polymerization takes place in the presence of one or more emulsifiers (E) having the following general formula: R1—N(R2)(R3), where R1 is a moiety with 15 to 40 carbon atoms which contains at least one aromatic group and at least one aliphatic group, and which contains at least one functional group selected from hydroxyl groups, thiol groups, and primary or secondary amino groups, and/or has at least one carbon-carbon multiple bond, and R2 and R3, independently of one another, are the same or different aliphatic moieties containing 1 to 14 carbon atoms. The invention further relates to a method for producing the primary dispersions, and to coating agents which include the primary dispersions, and to the use of the primary dispersions for producing electrodeposition coatings, and also to conductive substrates coated with the coating compositions.
