Cyanamide salts of non-lead metals as corrosion inhibitive pigments in mirror back coatings |
摘要 |
Compositions of the invention comprise an organic film-forming resin and a cyanamide salt of a non-lead metal. The composition, when applied to a thin metallic film, inhibits degradation of the thin metallic film as compared to the composition without calcium cyanamide. Processes comprising the step of applying a composition of the invention to a thin metallic film and articles comprising a thin metallic film and a layer of a hardened composition of the invention are also disclosed.
