PURPOSE: To provide a lamination type pressure-sensitive recording sheet concealing recording content. CONSTITUTION: A color former and a coupler both of or one of which is microencapsulated are independently laminated to the single surface of a support 5 or mixed to be laminated thereto to provide a single pressure-sensitive recording layer 4 and a surface laminate layer composed of a thermoplastic resin is further provided thereon to form a laminated pressure-sensitive recording sheet 7 and this sheet 7 and an opaque cover sheet 6 wherein a rear laminate layer 2 composed of a thermoplastic resin is provided on the single surface of a cover base material 1 are laminated so that the surface and rear laminate layers 3, 2 are bonded in a releasable manner to produce a lamination type pressure-sensitive recording sheet 9. Therefore, by pressing the recording sheet 9 on the side of the opaque cover sheet, data can be recorded on the internal pressure-sensitive recording part and the peeled opaque cover sheet is not again bonded. This recording sheet 9 has good releasability and seeing-through preventing function.
