Abstract
A resinous composition for coating use comprising an amphoteric resin having an acidic resinous component and a basic component of a basic compound, and an amino-formaldehyde resin etherified with monohydric alcohol having 1 to 4 carbon atoms and/or isocyanate compound, which is characterized by the fact that the basic component of a said amphoteric resin consists of a basic compound whose titration midpoint potential in non-aqueous potentiometric titration, when incorporated into the resin, is less than 450 mV, and the basicity of the amphoteric resin is within the range of 1.0.times.10.sup.-2 to 1.0 m mol/g solid. This composition can exhibit excellent pigment dispersibility and is useful as resinous vehicle for a coating composition to be used as a top coat for automobile bodies and the like.
