Abstract
A stable, aqueous epoxy resin dispersion including: (A) an epoxy resin prepared by condensation of at least one epoxide compound having on average at least two epoxide groups per molecule, with an aralkylated polyhydroxy aromatic compound obtained by reaction of a polyhydroxy aromatic compound with an aromatic compound which carries an alkenyl group; (B) a dispersant; and water, is useful, for example, in a coating or adhesive.
