Solid compositions comprising (A) a solid addition polymer containing units derived from at least one of acrylic or methacrylic acids and esters threof and from at least one epoxyalkyl ester or ether, and (B) aliphatic polycarboxylic acids (either monomeric or polymeric) having a first acidic dissociation constant no greater than 10<->3, optionally in combination with a pigment and other known additives, are useful for coating metal surfaces, preferably by electrostatic powder coating methods. The coatings produced from these compositions are suitable as automobile body and wheel coatings.
