  • Patent number: 9624581
    Abstract: A composition that includes a high-valent compound of copper, silver or indium; a linear, branched or cyclic C1-18 alcohol; and a Group VIII metal catalyst forms a metal film of copper, silver or indium on a substrate when the composition is coated on the substrate and heated to reduce the high-valent compound. The composition may alternatively include metal particles of silver, copper or indium in which the surface layer of the particle includes a high-valent compound of copper, silver or indium. A metal film of copper, silver or indium may also be formed on a substrate by coating a substrate with the composition including the metal particles, and heating to reduce the high-valent compound in the same manner as above.

  • Publication number: 20110183068
    Abstract: To provide a composition with which a metal film can be directly produced from a high-valent metal compound, a method for producing a metal film, and a method for producing a metal powder. Using a composition for production of a metal film of copper, silver or indium, which comprises a high-valent compound of copper, silver or indium, a linear, branched or cyclic C1-18 alcohol and a Group VIII metal catalyst, a coating film is formed, followed by reduction by heating to produce a metal film of copper, silver or indium. Further, using metal particles of silver, copper of indium having a surface layer comprising a high-valent compound of copper, silver or indium, instead of the high-valent compound of copper, silver or indium, a metal film of copper, silver or indium is produced in the same manner as above.
