<P>PROBLEM TO BE SOLVED: To provide a thermal recording object with barrier nature, excellent refractory, and high recording sensibility. <P>SOLUTION: In the thermal recording object in which a thermal recording layer comprising at least a leuco dye, a coloring agent and an adhesive and a protection layer are sequentially provided on a support, the fusing point of the above coloring agent is 140°C or more, the mean particle diameter of the above leuco dye and the coloring agent is being in a range of 0.2-0.6 μm, respectively. It is preferred that a sensitizer contains further in the thermal recording layer, and it is in the range whose mean particle diameter of the above sensitizer is 0.2-0.6 μm. <P>COPYRIGHT: (C)2007,JPO&INPIT |
