A process for preparing an aqueous dispersionncoating material containing a resin component having ansoftening temperature of from 10 to 250°C, whichncomprises:n (1) a step of mixing various starting materials whichnwill be coating film-constituting components, to obtain anblend material, (2) a step of melting and kneading the blend materialnat a temperature of at least the softening temperature ofnsaid resin component, to obtain a homogenized material, (3) a step of cooling and solidifying the homogenizednmaterial, followed by crushing, to obtain coarsenparticles, and (4) a step of wet-pulverizing the coarse particles innan aqueous dispersant, to obtain an aqueous dispersionncoating material containing fine particles having annaverage particle size of at most 10 µm. |
