PURPOSE: To make bonding strength in preservation at high temperature invariable by a method wherein a pressure sensitive recording layer containing a color coupler and a developer, a polyolefin resin laminated layer, an electron beam setting layer of a specific composition, etc., are laminated on a base material.

CONSTITUTION: A pressure sensitive recording layer 3 wherein a color coupler and a developer of which both or either are contained in a microcapsule are respectively independently laminated or mixed, a polyolefin resin laminated layer 3, an electron beam setting resin layer 4 wherein a weight mixing ratio of a non-silicone electron setting resin and a silicone electron setting resin is 99/1-20/80, and an opaque covering sheet 5 are successively laminated on a side surface of a base material to prepare a pressure sensitive recording sheet. Silicone electron beam setting silicone resin is hardened in a polymerized state by radiating electron beams under a state wherein it is mixed in non- silicone electron beam setting resin. Therefore, a silicone component capable of preventing a peeling off property and an excess polymerization-preventive property from occurring is fixed in the electron beam setting resin.
