ABSTRACT:
A branched acrylic copolymer with a core which is insoluble in a non-polar organic solvent and formed from the polymerization of an ethylenically unsaturated monomer with at least about 5% by weight of acid functionality wherein a catalyst such as a phosphonium compound is reacted with the acid functionality of the core, and organic solvent-soluble macromonomer stabilizers grafted to the core, is useful as a catalytic component in a coating composition comprising a non-cyclic anhydride resin and a resin derived from an ethylenically unsaturated epoxy monomer.
