<P>PROBLEM TO BE SOLVED: To provide a thermosensitive recording body which has sufficient heat resistance even when being exposed under high-temperature environment, hardly causes surface fogging and has extremely high recording sensitivity. <P>SOLUTION: The thermosensitive recording body includes a thermosensitive recording layer containing a dye precursor-containing composite fine particles and a developer, on a support, wherein the dye precursor-containing composite fine particles are composite fine particles obtained by polymerizing polyvalent isocyanate compound-containing polymerizing component in the presence of polyethylene imine, after emulsifying and dispersing a solution in which the polyvalent isocyanate compound-containing polymerizing component is made a solvent and the dye-precursor is made a solute. The polyvalent isocyanate compound-containing polymerizing component includes dicyclohexyl methane-4, 4'-diisocyanate, m-tetramethyl xylylene diisocyanate and an isocyanurate of hexamethylene diisocyanate. <P>COPYRIGHT: (C)2011,JPO&INPIT |
