A process for producing an aqueous hydrophobic-melamine-resin dispersion which has excellent storage stability and can give a coating film excellent in adhesion and surface smoothness; and a water-based color coating material capable of giving a coating film excellent in coloration, adhesion in re-coating, chipping resistance, and wet adhesion. The water-based color coating material comprises a film-forming resin, a hardener, and a pigment, wherein the film-forming resin comprises an acrylic resin emulsion produced by emulsion polymerization having an acid value of 1-30 mg-KOH/g and a hydroxy value of 10-150 and the hardener comprises an aqueous dispersion of a hydrophobic melamine resin having a particle diameter of 20-140 nm. |
