The present invention provides a coating composition which cures at low temperatures to form a cured film having high solvent resistance. The present invention provides a low-temperature-curable coating composition which comprises (A) a film-forming polymer having a hydrogen-donating functional group that has a heteroatom which bonds covalently to a hydrogen atom, (B) a film-forming polymer having a specific hydrogen-accepting functional group that has a heteroatom to which no hydrogen atom bonds covalently, and (C) a non-basic volatile solvent selected from the group consisting of a non-basic volatile solvent (C-1) having, in the molecule, both a heteroatom that bonds covalently to a hydrogen atom and a heteroatom that does not bond covalently to a hydrogen atom; a mixture of a non-basic volatile solvent (C-2) having, in the molecule, a heteroatom which bonds covalently to a hydrogen atom and a non-basic volatile solvent (C-3) having, in the molecule, a heteroatom to which no hydrogen atom bonds covalently; and combinations thereof.
