The addition interpolymer when mixed with the polyepoxide reacts to form a cured, hard, stain and solvent resistant material. The stability of the mixed compositions, i.e., its potlife, is lengthened by utilizing a sterically-hindered tertiary amine to form the salt groups of the interpolymer.Stability of the addition interpolymer prior to mixing is improved by utilizing therein monomers which provide aminolysis-resistant groups in the interpolymer.
