ELECTRODEPOSITION COATING MATERIAL CONTAINING ORGANIC POLYHYDROXY-FUNCTIONAL ANTICORROSION AGENTS

Described herein is an electrodepositable coating material including comprisingone 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.
