THERMOSENSITIVE RECORDING MATERIAL

PROBLEM TO BE SOLVED: To provide a thermosensitive recording material with less color mixing and stain. SOLUTION: The thermosensitive recording material has the first coloring layer containing a diazonium salt coloring by low energy and a coupler, the second coloring layer containing a diazonium salt coloring by medium energy and a coupler, and the third coloring layer containing an electron donating dye precursor coloring by high energy and an electron accepting compound. The electron donating dye precursor and the electron accepting compound in the third coloring layer are solid-dispersed, and the melting points of the electron donating dye precursor and/or the electron accepting compound are 200-300°C.
