Adhesion promoting compositions and method of improving fuel resistance of a coated article

A film-forming composition comprising:

• A) a non-chlorinated, linear polyolefin polymer comprising 0.5 to 10 percent by weight residues of an ethylenically unsaturated anhydride or acid, based on the total weight of the linear polyolefin polymer;
• B) an aminoplast;
• and
• C) a component comprising:
• i) at least one non-chlorinated hydrocarbon having at least 18 carbon atoms and which optionally includes aromatic groups and/or oxygen heteroatoms, having a number average molecular weight of 200 to 2500;
• and/or
• ii) an alkyd resin that is different from the component C) i);
• wherein the linear polyolefin polymer A) is dispersed with a diepoxide and a monohydric alcohol comprising isopropanol and/or n-butanol in an organic medium;
• and wherein the linear polyolefin polymer A) is further reacted with the diepoxide and the monohydric alcohol.
