Abstract
The present disclosure is directed to an electrodepositable coating composition comprising a cationic salt-group-containing, film-forming resin dispersed in an aqueous medium, the cationic salt-group-containing, film-forming resin comprising the reaction product of a reaction mixture comprising: (a) a polyepoxide; (b) at least one polyol comprising an aliphatically substituted phenol comprising at least two phenolic hydroxyl groups; and (c) a cationic salt group former. The present disclosure is also directed to methods of coating substrates and coated substrates.
