PROBLEM TO BE SOLVED: To provide a falsification-proof pressure sensitive reproducible slip protected against falsification by an additional entry. SOLUTION: This falsification-proof pressure sensitive reproducible slip consists of two developer sheets 1, 3, each of which has a developer layer 5 formed on, at least, one of the faces of a support 4, and a color coupler sheet 2 with a microcapsule layer 6, enveloping an electron-donative sheet color coupler, provided on both surfaces of the support 1, in such a manner that the color coupler sheet 2 is sandwiched between the mutually opposed developer layers 5 of the developer sheets 1, 3. |
