Abstract
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 EQU C.sub.3 N.sub.3 (NHCOOR).sub.3 (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.)
