ABSTRACT:
An electrically nonconductive copper-boron film is deposited on the surface of a substrate, particularly a nonmetallic substrate such as glass, by reducing a copper salt with a small amount of alkali metal borohydride in the presence of a complexing agent such as Rochelle salt or ethylenediamine tetraacetate salts. The resultant copper-boron coated substrate may be further heated until it assumes a copper-bronze appearance by reflection, resulting in a copper-boron coated article, or the copper-boron coated substrate may be subjected to chemical reduction, resulting in a copper coated article of superior uniformity.
