PURPOSE:To prevent texture fog, and to improve color development sensitivity and picture shelf stability by using a specific fluoran compound as a leuco dye in a photosensitive recording material in which a color developing layer containing a colorless or light-colored leuco dyestuff and an organic developer is formed onto a support. CONSTITUTION:In a photosensitive recording material in which a color developing layer containing a colorless or light-colored leuco dyestuff and an organic developer color-developing the leuco dyestuff at the time of heating is shaped onto a support, 2-anilino-3-methyl-6-(N-iso-butyl-N-methoxyethyl)aminofluoran shown in structural formula is used as the leyco dyestuff. Accordingly, texture fog, color development sensitivity and picture shelf stability are improved, and the title thermal recording material having a high jndustrial utility value is acquired. |
