Abstract
A process for producing an aqueous dispersion of vinyl acetate-ethylene copolymer containing an epoxide resin, which comprises emulsion-copolymerizing vinyl acetate, wherein an epoxide resin is dissolved, and ethylene at a pH value of 3 to 7 so that the ratio of vinyl acetate to ethylene is 60-95 : 40-5 by weight and the content of the epoxide resin is 0.5 to 60% by weight on the basis of the total weight of the solid resin components. The aqueous dispersion is useful as a two-pack type adhesive or coating composition in combination with a curing agent.
