The electrodepositable coating composition is an aqueous dispersion comprising of an at least partially neutralized copolymer comprising α-olefin and unsaturated carboxylic acid and a curing agent. After a layer of the coating composition has been applied to the substrate, it can be heated to cure the coating and form a crosslinked network that provides a durable chip and corrosion resistant finish. ## Claims ### Claim at position 1 1-9.
