PURPOSE:To form a developed color image having necessary developed color density from an upper sheet to a lower sheet by providing a color self- developing type pressure-sensitive sheet having microcapsules including an electron donating color former and a color self-developing layer provided thereto and a self-supporting plastic transparent sheet to the upper surface of a support. CONSTITUTION:When a developed color image is formed on color self-developing type pressure-sensitive sheets 20, a pressure printer is used and an ink ribbon is not used to apply printing to a plastic transparent sheet 30 in the direction shown by an arrow By this pressure printing, the microcapsules of the color forming layers 22 of both color self-developing type pressure-sensitive sheets 20 are dustructed. Accompanied by this, the color former included in the microcapsules is reacted with the coupler of coupler layers 23 to develop a color to form developed color images 40. At the time of this printing, the developed color images 40 are not substantially transferred to the plastic transparent sheet 30 and transparency is kept. |
