摘要： The water dispersible resin of the present invention is contained in a base component of a two-component thermosetting resin composition. The water dispersible resin is prepared by dispersing a solvent resin in water, which solvent resin is obtained by solution polymerization, carried out in two or more stages, of a monomer mixture containing a polyfunctional monomer, an acid group-containing monomer, and a hydroxyl group-containing monomer, the polyfunctional monomer having a plurality of vinyl groups in its single molecule. The monomer mixture contains the polyfunctional monomer by not less than 0.1% by weight but not more than 3% by weight, and the water dispersible resin thus obtained has an acid value of solid content of not less than 10 mgKOH/g but not more than 45 mgKOH/g, a hydroxyl value of solid content of not less than 50 but not more than 200, and a viscosity of not less than 50 mPa·s but not more than 10,000 mPa·s when a nonvolatile content is 45% by weight. This makes it possible to provide a two-component thermosetting resin composition, which is easily dealt with, formed into a coating film having an excellent appearance, and further, has an excellent pot life.
