ABSTRACT:
A polyester resin aqueous dispersion which provides a coating film having excellent processability, water resistance, corrosion resistance, chemical resistance, weather resistance and adhesion to various substrates, and which also has markedly excellent storage stability even at a high solids concentration. The polyester resin aqueous dispersion substantially comprises a specific polyester resin, a basic compound, an amphipathic organic solvent capable of plasticizing the polyester resin, and a compound having a protective colloid action. Furthermore, fine particles of the polyester resin are homogeneously dispersed in an aqueous medium and in a specific dispersed state.
