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 which are contained in a microcapsule, an electron beam setting resin layer containing a radical polymerization inhibitor, etc., are laminated on a base material. CONSTITUTION:A pressure sensitive recording layer 2 containing a color coupler and a developer of which both or either are contained in a microcapsule, a polyolefin resin laminated layer 3, an electron beam setting resin layer 4 containing a radical polymerization inhibitor by a concentration of 1000-10000ppm per weight of the electron beam setting resin, and an opaque covering sheet 5 are successively laminated on a side surface of a base material to prepare a thermosensitive recording sheet. There are hydroquinone group, dichlorobenzoquinone group, etc., as concrete examples of the radical polymerization inhibitor, and there is a compound having ethylene unsaturated bond as a concrete example of the electron beam setting resin. Further, there are glassine paper, wood free paper, art paper, coated paper, etc., as the base material 1 and the opaque covering sheet 5. |
