摘要:
A thermosensitive recording material comprising a substrate sheet and a thermosensitive colored image-forming layer formed on at least one surface of the substrate sheet and comprising at least one colorless or light-colored dye precursor and a color-developing agent reactive with the dye precursor upon heating to thereby develop a color, wherein the color-developing agent comprises at least one compound of the formula (I): (wherein R1 represents a member selected from the group consisting of unsubstituted aromatic hydrocarbon groups and substituted aromatic hydrocarbon groups with at least one substituent selected from the group consisting of a methyl group and a chlorine atom, and R2 represents a divalent organic group).
