Abstract
Abstract A composition consisting essentially of reaction products of an ammonium salt of an aliphatic acid and a gold complex of a reactive nitrogen-containing organic compounds is soluble in organic solvents and can be used for various purposes including decorating substrates and in the manufacture of printed circuit boards. Typical reaction products include the reaction product of ammonium decanoate and the gold or platinum complex of 1, 2-diaminopropane. The process for producing the composition involves reacting a precious metal salt with a reactive nitrogen containing organic compound to form the precious metal complex and reacting an organic nitrogen compound containing a reactive nitrogen group such as an amino group and an aliphatic acid to form an ammonium salt of an aliphatic acid. Thereafter the ammonium salt is reacted with the precious metal nitrogen organo complex to form the compositions of this invention.
