ABSTRACT:
An improved electrochemical recording medium is provided which comprises a support impregnated with an electrolytically conducting solution containing an electrolyte, a chelating or sequestering agent, and a marking compound; and characterized by the inclusion of a six-membered hetero-aromatic nitrogen-containing compound having at least one acidic substituant adjacent to a nitrogen atom of the hetero-aromatic ring. The hetero-aromatic compound unexpectedly provides improvement in color, tone and definition of recorded mark.
