The present invention relates to a cationic pigment grinding resin and an electrodepositable coating composition comprising the same. More specifically, the present invention relates to a cationic pigment grinding resin, as a polyepoxide-amine resin, comprising (i) an acid-neutralizable amine group derived from monoepoxide- amine compound resulting from the reaction of monoepoxide and amine having 3 and more active hydrogen, and (ii) a quaternary ammonium salt group, in the middle of its chain, and an electrodepositable coating composition comprising the same.
