To obtain paint compositions with which it is possible to form paint films which have excellent acid resistance, weather resistance and heat resistance and which also have excellent yellowing resistance. A heat hardenable paint composition which contains (A) polyol which has in each molecule two or more sterically protected secondary hydroxyl groups, being a polyol obtained by means of an esterification reaction of an epoxy group containing compound which has one epoxy group and which does not have a polymerizable unsaturated bond and a carboxyl group containing compound which has two or more carboxyl groups; and (B) 1,3,5-triazine-2,4,6-tris-carbamic acid ester which can be represented by the general formula indicated below, or an oligomer thereof, wherein the mol ratio secondary 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.General Formula(In this formula, 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 to 20 carbon atoms.)
