PURPOSE:To secure the concealment of recorded contents and enable a shielding part to be easily separated to disclose the contents by disposing a pressure- sensitive recording layer, a polyolefin resinlaminated layer and a thermoplastic resin-laminated layer in order on one surface of a support and forming the shielding part so that it can be separated between both the laminated layers. CONSTITUTION:A pressure-sensitive recording sheet 7 is formed by disposing a self-color forming type pressure-sensitive recording layer 2, a first polyolefin resin-laminated layer 3 and a second thermoplastic resin-laminated layer 4 in order on one surface of a support 1. A color forming agent or a developer, both of or one of which is micro-capsulized, is singly laminated on the pressuresensitive recording layer 2, respectively, or both the agents are mixed together and applied to the layer 2. Further, white or color dyeing pigments 6 are contained in the thermoplastic resinlaminated layer 4. It is so designed that a shielding part can be separated between the first and second laminated layers 3, 4. In this way, recorded contents are reliably concealed, and, when information is disclosed, the shielding part is easily separated so that the contents can be read.
