A self-copying paper for composing printed forms and other prints arranged in multiple stacked sheets comprises, on the back side thereof, a thermoplastic matrix in which is dissolved a leuco toner and, on the front side, a uniform layer including a toner developing agent. The toner on the back side of one sheet is adapted to be transferred by a localized pressure, to the front side of the next underlying sheet, and is developed there by the action of the developing agent. |
