ABSTRACT:
The present invention provides a reactive acrylic oligomer obtained by the method of polymerizing at least one .alpha., .beta.-ethylenically unsaturated monomers having no oxirane ring and/or carboxyl groups, in an organic solvent and in the presence of azo initiator having carboxyl group and tertiary amine, and then reacting the same with a compound having .alpha., .beta.-ethylenically unsaturated bonding and oxirane ring. The invention further provides a grafted acrylic resinous composition obtained by the method of copolymerizing said reactive acrylic oligomer with at least one .alpha., .beta.-ethylenically unsaturated monomers which will constitute the backbone of the graft polymer, as well as the coating composition containing as resinous vehicle the abovesaid resinous composition and especially the resinous composition whose graft polymer is an amphoteric acrylic resin having backbone chain with acidic groups and branched chains with concentrated quantity of basic groups.
