PURPOSE:To obtain a pressure-sensitive copying sheet which contains a capsule ink enveloping an electron-donative coloring agent on one surface of a sheet and displays excellent color development properties, if the capsule ink is used for type printing or offset printing. CONSTITUTION:The pressure-sensitive copying sheet is obtained by printing an ink which contains a microcupsule enveloping an electron-donative coloring agent on one surface of a support. In addition, the copying sheet uses a sheet with an air permeability of 35'' max based on JIS-P-8117 or a sheet with a pigment-coated layer on one surface as a support. Further, the copying sheet undergoes type printing or offset printing of the capsule ink on the sheet surface of the support. |
