An aqueous dispersion coating material containing, as a film-forming constituent, an aqueous dispersion that can be obtained by contacting with an aqueous medium, a base-neutralized resin reaction product with an acid value of 10 to 30 which can be obtained by reacting a water-soluble epoxy-denatured alkyd resin with an epoxy resin in solid state at ordinary temperature and by adding and polymerizing at least a part of these resins and then neutralizing the resin reaction product with a base. Because this coating material has been emulsified in a translucent colloidal emulsion region with an aqueous medium, its finished appearance and corrosion resistance are superior and its structural viscosity can be controlled without damaging the storage stability through the addition of organic solvents, and the excellent finished appearance can also be obtained by atomization coating in addition to immersion coating, flow coating and the like, of vertical areas, and this coating material has applicability to a variety of coating methods.
