The invention relates to a heat-hardenable paint composition which contains (A) vinyl based copolymer of hydroxyl group value from 20 to 200 mg KOH/g, being a copolymer of from 5 to 70 wt.% hydroxyl group containing vinyl based monomer which can be represented by general formula (1) and from 95 to 30 wt.% other vinyl based monomer (a-2), and (B) 1,3,5-triazine-2,4,6-triscarbamic acid ester which can be represented by general formula (2): C 3 N 3 (NHCOOR) 3 or an oligomer thereof, in which the mol ratio of hydroxyl groups originating from the aforementioned (A) component: NHCOOR groups originating from the aforementioned (B) component in the composition is from 1:3 to 3:1. In general formula (1), X 1, X 2 and X 3 each independently represent a hydrogen atom or a methyl group. Moreover j is an integer of value from 0 to 2, m is an integer of value from 3 to 5, and n is an integer of value from 0 to 5. However, j and n cannot both be 0. In general formula (2), R represents an alkyl group which has from 1 to 20 carbon atoms, an aryl group which has from 6 to 20 carbon atoms or an aralkyl group which has from 7 to 20 carbon atoms, and these groups may be the same or different.
