An o/w water paint having excellent dispersibility and stability is prepared according to a phase conversion process comprising adding ammonia or an amine and water to a solution of an epoxy resin, a hardener resin, and an acrylic resin in an organic solvent or to a molten mixture of these resins to neutralize the acrylic resin. In view of adhesion of a coat to metal and workability, branched alkylamines or heterocyclic amines are suitable as the neutralizing amines. In applying this paint, steam optionally containing fine water droplets is preferably applied to a wet coat prior to drying. Furthermore, a process for the continuous production of an emulsion type water paint comprising a carboxyl group-containing acrylic resin component, an epoxy resin component and a curing agent resin component for the epoxy resin is disclosed.
