PURPOSE:To obtain a thermal recording sheet, in which recording contents are concealed, by unifying a thermal recording layer by respectively laminating a micro-capsulated color former and developer or applying them in a mixed state on one surface of a support respectively and an opaque coating sheet through a themoplastic resin laminated layer. CONSTITUTION:A pressure-sensitive recording layer 3 applied by respectively laminating or mixing a color former and a developer, both or one of which is micro-capsulated, on one surface of a support 4 and an opaque coating sheet 1 are unified through a thermoplastic resin laminated layer 2. The thermoplastic resin laminated layer 2 is bonded strongly with the pressure-sensitive recording layer 3 side and bonded weakly with the opaque coating sheet 1 side at that time. The thickness of the thermoplastic resin laminated layer 2 is set in 10-50mum. Accordingly, pressure-sensitive recorded information can be treated without being publicly exposed to the outside, and the opaque coated sheet is peeled at need and information pressure-sensitive recorded on the inside can be read. |
