PROBLEM TO BE SOLVED: To obtain a thermosensible recording material which has a high coloring sensitivity, enables fixation by radiation of light and has a high whiteness degree and which causes little fogging of white paper. SOLUTION: In a thermosensible recording material prepared by providing on a substrate a thermosensible coloring layer which develops color by heating, the thermosensible coloring layer contains an oxidation colored type leuco dye, an oxidizing agent and a photoreduction agent and the oxidation colored type leuco dye is enveloped in a microcapsule for which polyurea or polyurethane-polyurea formed of a polymerization component containing aliphatic isocyanate is used as a wall film. |
