ABSTRACT:
An improved electrolytic printing fluid is described. The printing fluid is comprised of an agent for the catalyzation of the electro-oxidation of a color forming agent therein. The fluid may include an agent which can form a clathrate complex with the color forming agent, as well as an agent which prevents discoloring of the paper when said fluid is coated on the same. The coated paper is subjected to an electrolytic printing method using non-consumable electrode.
