Abstract
A process for forming a layer of gold on a substrate, comprising: preparing a solution of a gold precursor wherein the gold precursor consists of Au(OH).sub.p (OOCR.sup.1).sub.q (OOCR.sup.2).sub.r wherein R.sup.1 is selected from the group of hydrogen, alkyl, alkenyl, and alkynyl, and R.sup.2 is selected from the group of hydrogen, alkyl from 2 to 10 carbon atoms, alkenyl, or alkynyl, and p+q+r=3. Applying the solution of the gold precursor to the surface of the substrate. Decomposing the gold precursor by subjecting the gold precursor to heat.
