Abstract

Earlier work with electrolytic printing systems has considered only potassium and ammonium bromide salts as the conductive medium and oxidant-catalyst system in the electrolyte. Other minor component additives have been added to contribute to other aspects of printing behavior, such as buffering (phosphate salts) or print stability (fluoride salt to stabilize starch-iodide printing). It is possible, however, to separate the electrolyte functions of conductivity and oxidant-catalyst to a certain extent and, thus, introduce alternate bromide salts and additional conductive salts to the electrolyte system to replace potassium bromide in equivalent amounts, thereby lowering the overall cost without sacrificing performance.
