The coating composition comprises such a resin composition and a cationic polymerization catalyst, wherein the content of an organic solvent content is 0 to 40 wt. %. Since the present composition contains a low molecular weight oligomer, the viscosity of the composition is low even though the solid content is high. Accordingly, the content of the organic solvent can be much reduced.
