PURPOSE: An aqueous resin dispersion that contains a specific amount of a photosetting compound and a polyester or polyurethane containing a dicarboxylic acid having metal sulfonate groups, thus containing fine particles which form coating films with high water and heat resistance.
CONSTITUTION: The objective aqueous dispersion comprises (A) a polyester in which 0.5W20mol% of the polycarboxylic acid component is a dicarboxylic acid containing metal sulfonate groups and, a photosetting dicarboxylic acid or photosetting hydroxycarboxylic acid and/or photosetting glycol occupies 0.01W 50mol% of the acid component and/or the glycol component, or a polyurethane obtained from the above polyester and a polyisocyanate, (B) a water-soluble organic compound boiling at 70W200°C and (C) water wherein the weight ratio of A/B/C is (5W70)/(0W50)/(95W20) and B/C is 0W0.66.
