摘要：
A process for preparing an aqueous dispersion coating material containing a resin component having a softening temperature of from 10 to 250°C, which comprises:
(1) a step of mixing various starting materials which will be coating film-constituting components, to obtain a blend material,
(2) a step of melting and kneading the blend material at a temperature of at least the softening temperature of said resin component, to obtain a homogenized material,
(3) a step of cooling and solidifying the homogenized material, followed by crushing, to obtain coarse particles, and
(4) a step of wet-pulverizing the coarse particles in an aqueous dispersant, to obtain an aqueous dispersion coating material containing fine particles having an average particle size of at most 10 µm.
