Abstract
Tertiary amine terminated resinous compositions are prepared by reacting a molar excess of a polyepoxide compound with a dihydric phenol in a large excess of a monoamine which contains one tertiary amine group and one primary hydroxyl group. The resinous composition can be salted with an acid and can be dissolved or dispersed in water. The aqueous dispersions or solutions can be formulated into primer coatings for metal objects.
