ABSTRACT:
In accordance with the present invention, metal pigments are provided which are normally reactive with water or moisture to release hydrogen gas ("gassing") and which have been stabilized against such gassing by having their surfaces treated with an adduct of a maleinized fatty acid and/or a maleinized alpha-olefin and a polyol. Waterborne film-forming compositions which comprise an aqueous diluent medium, a film-forming polymer, and metal pigment stabilized against gassing by treatment with an adduct of a maleinized fatty acid or a maleinized alpha-olefin and a polyol are also provided.
