PROBLEM TO BE SOLVED: To provide a thermosensitive recording material that has high recording density, has very good oil resistance and plasticizer resistance at the recording part and is excellent in background fogging resistance when stored under a high temperature or high humidity condition.SOLUTION: The thermosensitive recording material has a thermosensitive recording layer containing at least a leuco dye and a coloring agent on a support. The coloring agent contains 4,4'-bis(3-tosylureido)diphenylmethane and N-[2-(3-phenylureido)phenyl]benzenesulfonamide. It is preferable that the 4,4'-bis(3-tosylureido)diphenylmethane is contained in a ratio of 0.2-4.0 pts.mass based on 1.0 pt.mass of the N-[2-(3-phenylureido)phenyl]benzenesulfonamide. |
