<P>PROBLEM TO BE SOLVED: To provide a thermal recording medium which has a high recording sensitivity, enables attainment of a good image quality even by printing with a low energy and moreover has a magnetic recording characteristic on the back side. <P>SOLUTION: The thermal recording medium is constituted by sequentially forming an undercoat layer and a thermal recording layer containing a leuco dye and a developer on one side of a paper substrate. The undercoat layer is constituted at least of two undercoat layers of a first and a second, and a standard deviation of the thickness of the thermal recording layer is 0.30 or less with the magnetic recording characteristic carried by the other side of the paper substrate. <P>COPYRIGHT: (C)2008,JPO&INPIT |
