    摘要: Powder coating compositions are disclosed which, exclusive of pigments and other nonreactant components comprise a coreactive mixture of: (A) a copolymer of between about 5 and about 20 weight percent of a hydroxy bearing monomer and between about 95 and about 80 weight percent of other monoethylenically unsaturated monomers, said copolymer having a glass transition temperature in the range of about 40.degree. C to about 90.degree. C and a number average molecular weight (M.sub.n) of between about 2000 and about 10,000; and an organic di- or poly-carboxylic acid or di- or poly-carboxylic acid anhydride crosslinking agent, said crosslinking agent being present in an amount of from about 0.8 to about 1.1 crosslinkable functional groups for each hydroxy group in the copolymer.
