Abstract: Described herein is an electrodepositable coating material including comprising one or more cathodically electrodepositable resins (A); one or more crosslinking agents (B); and one or more compounds represented by formula (I) where C(R1)(R2) is C═O or CH2; R3 is H or OH; R4 and R5 are H or OH, with the proviso that at least one of R4 and R5 is H; and R6-R7 is C═C or HC—CH. Also described herein is a method of coating a metallic substrate comprising including the steps of dipping a metallic substrate into an electrodeposition bath containing the electrodepositable coating material; switching the substrate as a cathode; depositing the electrodepositable coating material onto the substrate to form a coating layer; and drying and curing the thus formed coating layer. Further described herein is a method of using the compounds of formula (I) as anticorrosion agents in electrodeposition paints and coated substrates.

Abstract: The present invention relates to a use of an aqueous coating composition for applying a topcoat to at least one side of a substrate metal surface coated at least with a primer coat, said aqueous coating composition comprising at least one binder (A) in dispersion or solution in water, at least one crosslinking agent (B), at least one second binder (C) in dispersion or solution in water, and optionally at least one pigment (D), the second binder (C) being a copolymer which is obtainable by copolymerization of ethylenically unsaturated monomers in the presence of at least one polyurethane resin having polymerizable carbon double bonds; to a process for coating a substrate metal surface coated at least with a primer coat, said process comprising at least one step of at least single-sidedly applying the aqueous coating composition as topcoat to the substrate metal surface coated at least with a primer coat; and also to a coated substrate obtainable by this process.
