PROBLEM TO BE SOLVED: To provide a pressure-bonding postcard sheet, a pressure-bonding postcard and method for manufacturing the pressure-bonding postcard capable of suppressing a transfer of an electronic watermark image or a two-dimensional code when the pressure-bonding postcard is peeled even if the electronic watermark image or the two-dimensional code is printed on an inner surface of the pressure-bonding postcard.SOLUTION: In a pressure-bonding postcard sheet, a first piece of paper 1a and a second piece of paper 1b are connected with each other via a bend line 4, and pressure-sensitive paste is applied on surfaces of the first piece of paper 1a and the second piece of paper 1b. On a surface of the first piece of paper 1a opposed to the second piece of paper 1b, an information recording image printing layer 2 in which an information recording image is printed by an ink jet printing system is formed. A transfer prevention layer 3 printed by the ink jet system is formed on a position, which the information recording image printing layer 2 is in contact with if two pieces of papers are folded by the bend line 4, in the second piece of paper 1b. |
