Abstract
The present invention is directed to an addition polymer comprising an addition polymer backbone; at least one moiety comprising a phosphorous acid group, the moiety being covalently bonded to the addition polymer backbone by a carbon-carbon bond; and at least one carbamate functional group. The present invention is also directed towards methods of making the addition polymer, aqueous resinous dispersions and electrodepositable coating compositions comprising the addition polymer, methods of coating a substrate and coated substrates.
