Abstract
A resinous composition for coating use comprising a resin having a resinous acid value derived from polycarboxylic acid whose titration midpoint potential in non-aqueous potentiometric titration is more than -300 mV under the state capable of developing resinous acid value of 2 to 50 and having a functional group reactive with a crosslinking agent, and preparation thereof. The composition is useful for the preparation of coating composition having improved curing property.
