Abstract
The properties of a thiocyanate free gold latensification solution are explored. A dilute solution of potassium tetrachloroaurate (III) produces photographic speeds almost as high as the conventional gold latensification formulation that contains potassium thiocyanate. During latensification, gold plates onto sub-image centers rather than replacing silver in those centers.
