Abstract
This invention relates to a composition comprising a copolymer of ethylene and a halogenated comonomer selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene and mixtures thereof and 0 to 10 mol percent of an additional monomer selected from the group consisting of 3,3,3-trifluoro-2-trifluoromethyl propene, a vinyl monomer which is free of telogenic activity and which provides a side chain having at least two carbon atoms, said side chain being aromatic or having its elements bonded together by a single bond only, or mixtures thereof, and containing from about 1 to about 40% by weight of an oxide of cobalt, nickel, manganese, chromium, tin, molybdenum, tungsten or mixtures thereof. Such compositions are particularly useful as a primer coating for substrates such as metals in conjunction with an overlying layer of such copolymers. Coated articles are provided which comprise a substrate, a primer coating fused thereon and comprising such composition and an outer coating of similar copolymers fused to the primer coating.
