<P>PROBLEM TO BE SOLVED: To provide a thermal recording medium which has advantages such as excellent recording density, improved oil resistance and plasticizer resistance of a recording part, and is free from a problematical texture blushing, even when preserved under a high temperature and high humidity condition. <P>SOLUTION: This thermal recording medium has a thermal recording layer containing a leuco dye and a developer on a support. For the developer, at least one selected from the group consisting of a 4,4'-(3-(tosyl)ureide) diphenylmethane, a 4,4'-(3-(tosyl)ureide) diphenylethane and a 4,4'-(3-(tosyl)ureide) dipheny lether, is used. Further, the developer contains 0.01 to 0.10 pt.mass of a tetrakis(1,2,2,6,6-pentamethyl-4-piperidyl)-1,2,3,4-butanetetracarboxylate, with respect to 1 pt.mass of the developer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
