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