Description
Summary:The objective of the present work is to develop an electrolytic process that can produce black colors of high light absorptivity quickly and efficiently without the use of unnecessary baths and sophisticated electrical equipment, which make the process more complicated and substantially increase the cost. This goal is to be achieved through use of additives in the coloring bath to impart pitting in the nonporous barrier layer to render it more conductive.
