Abstract
Described herein is an aqueous cathodically depositable electrodeposition coating material composition including at least one cathodically depositable polymer (a) and at least one carbon black pigment (b), where the at least one carbon black pigment (b) is a lamp black pigment having a number-based median primary particle size (d) of at least 50 nm and at most 200 nm. Also described herein is a method for at least partially coating an electrically conductive substrate by cathodic electrodeposition coating including immersing the substrate at least partially into an electrodeposition coating bath, which includes the electrodeposition coating material composition. Also described herein is an electrically conductive substrate, which is at least partially coated with a baked electrodeposition coating material composition and/or which is obtainable by the method. Further, described herein is a method of using the carbon black pigment (b) for improving corrosion protection and/or homogeneity of the film build.
