Abstract
A resinous composition for coating use which is excellent in weather resistance and in low temperature curing properties, comprising a resin having resinous acid value based on carboxyl groups derived from its constituting tetrachlorophthalic acid of 2 to 8, a resinous acid value based on sulfonic acid groups derived from its constituting sulfophthalic acid of 0.5 to 5, and a functional group capable of reacting with a crosslinking agent to be compounded with the resin. The present resin is useful, in the combination form with a crosslinking agent, as a resinous vehicle of a coating composition which is excellent in curing properties, weather resistance, pigment dispersibility and storage stability and is specifically useful as an intermediate or top coat paint for automobile bodies or the like.
