Powder coating composition

A resinous composition for a top coat comprising a polyester resin modified with a lactone, said polyester resin being characterized in that 10 to 80 mole % of acid component is an alicyclic polycarboxylic acid or anhydride thereof, and 10 to 100 mole % of the carboxyl groups capable of developing a resinous acid value is derived from a polycarboxylic acid which will show a potentiometric midpoint potential in a non-aqueous potentiometric titration, in the state being incorporated into the resin, of -350 mV or more. The coating composition based on said resinous composition is specifically useful as a top coat for automobile bodies in two-tone-color coating.
