ABSTRACT:
A resinous composition for coating use comprising a resin obtained by the reaction of base resin having as essential groups, both carboxyl groups derived from a polycarboxylic acid whose titration midpoint potential in non-aqueous potentiometric titration is more than -300 mV in a state capable of developing a resinous acid value and a functional group reactive with a crosslinking agent, and an alkyleneimine compound in an amount equivalent to resinous acid value of 0.01 to 50, the resinous acid value based on said polycarboxylic acid in the final composition being 2 to 50.
This is useful for the preparation of a coating composition having improved curing property, storage stability and time color stability.
