Abstract: Described herein are aqueous electrocoating materials including a silane-containing crosslinking agent, a process to produce an electrocoated substrate, an at least partly coated substrate obtained from said process, as well as a component including said at least partly coated substrate.

Abstract: Described herein is an electrodepositable coating material including one or more cathodically electrodepositable resins (A); one or more crosslinking agents (B); and one or more compounds represented by formula (I) where R1?H or OH; R2=a divalent radical selected from the group consisting of *C(O)—O, (HO)*CH—CH2 and *CH2—CH2, with * denoting the carbon atom which is bound to the benzene ring; and R3=a monovalent radical. Also described herein is a method of coating a metallic substrate 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.
