Abstract: Disclosed herein are aqueous compositions comprising a base-neutralized blend of non-gelled phosphated epoxy and a resin which is non-self dispersible with a base, in water. Coating compositions of these blends are stable and form hydrophobic films of enhanced film properties, particularly in the area of can coatings.

Abstract: Disclosed are novel water-souble, thermosettable resinous compositions derived by reacting a precondensate of dicyandiamide, formaldehyde, a salt of a water-soluble polyaminopolyamide and an ammonium salt with epihalohydrin and then condensing the reaction product with additional formaldehyde. The resinous compositions are cationic and have particular utility in the manufacture of paper sized with cellulose reactive sizing agents such as ketene dimer sizing agents.
