Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
136 words
A decorative coating composition for coating a surface of an article and for obtaining a metallic appearance of said surface consisting essentially of a settable organic binder, a powder of a single metal of a grain size not exceeding 1 mm and selected from the group consisting of copper, bronze, iron, tin, zinc, and noble metal powders, and a substantial amount of graphite particles, the ratio of said organic binder to said metallic powder and graphite particles being 15 to 200 parts of said organic binder to 100 parts of said metallic powder and graphite particles, said 100 parts of said metallic powder and said graphite particles consisting of 10 to 30 parts by weight of said graphite particles and 90 to 70 parts by weight of said metallic powder, said composition being free of solvent.
Claim 2
Dependent Claim
