ABSTRACT:
A heat-sensitive recording composition with an improved image stability comprises 3-(N-methylcyclohexylamino)-6-methyl-7-anilinofluorane, 4,4'-isopropylidenediphenol capable of color-developing the fluorane through reaction by heating, fatty acid amide as a sensitizer and water-insoluble modified phenol resin having a softening point of 80.degree. to 190.degree. C., where at least 20% by weight of N-monosubstituted fatty acid amide is contained on the basis of total fatty acid amide, and 5 to 50% by weight of the water-insoluble, modified phenol resin is contained on the basis of the 4,4'-isopropylidenediphenol.
