PURPOSE:To achieve securing a closed property of information and secrecy of no readhesion, and improve an adhesion property by a method wherein an opaque coating sheet is formed of paper having natural pulp as a main component and besides a specific smoothness degree on a laminate layer side of the sheet is set at a specific numerical value (s). CONSTITUTION:In a pressure sensitive recording sheet 5, a pressure sensitive recording layer 3 and an opaque resin coating sheet 1 are integrated on a side surface of a base material 4 via a melting extruded laminate layer 2. Then, a color coupler or a developer of which both sides or one side are microcapsulated, are respectively or mixedly applied to the pressure sensitive recording layer 3. In that case, the opaque coating sheet 1 is formed of paper having natural pulp as a main component. Further, a smoothness degree on a contact side with the laminate layer 2 of paper is set at 20s or higher in Bekk smoothness as specified in JIS-P8119. Furthermore, the laminate layer 2 comes in strong contact with the pressure sensitive recording layer 3 and comes in weak contact with the opaque coating sheet 1. Besides, a thickness of the laminate layer 2 is set at 10-50mum. |
