ABSTRACT:
An aqueous resin dispersion which comprises as the chief component acrylic-modified epoxy-polyamine resin composed of a bisphenolic epoxy resin containing at least two epoxy groups per molecule; and, as bound to at least a part of said epoxy groups, an acrylic resin having on the average at least one functional group which is capable of reacting with said epoxy group, per molecule, the molecular weight distribution of said acrylic resin as expressed by its weight average molecular weight (Mw)
umber average molecular weight (Mn) being within a range of 1 to 1.2, and an active hydrogen-containing amino compound. Said aqueous resin dispersion may further optionally contain non-ionic, film-forming resin. Such dispersions are useful for cationic electrodeposition paint which can form a coating excelling in weatherability and corrosion resistance.
