ABSTRACT:
An amine resin soluble in water with the aid of an acid is produced by reacting a dihydric phenolic compound with a stoichiometric deficiency of aromatic diepoxide, then reacting the product with formaldehyde to generate methylol groups on the aromatic moieties present in the product, then reacting at least a portion of the methylol groups with monosecondary amine to produce a Mannich base, and then reacting the Mannich base with additional diepoxide in an amount of from 0.5 to 2 epoxy equivalents per epoxy equivalent in the initially used diepoxide.
