Disclosed is a water-based thermosetting epoxy composition of a water compatible epoxy resin, about 5 to about 35%, based on a total solids, of a water compatible impact modifier, about 1.5 to about 7%, based on the weight of the epoxy resin, of a water compatible epoxy hardener, up to about 0.3%, based on the weight of the epoxy resin, of a catalyst, and sufficient water to provide a viscosity of about 100 to about 500 centipoises. The impact modifier is a copolymer of about 10 to about 60% ethylene, propylene, or mixtures thereof, and about 40 to about 90% vinyl acetate, vinyl chloride, or mixtures thereof. Also disclosed are laminates prepared from this composition and a method of preparing them.
