Heat-sensitive recording sheet |
| abstract |
A heat-sensitive recording sheet of this invention comprises in a heat-sensitive color-developing layer both bis(4-hydroxyphenyl)butylacetate as an organic color-developing agent and a particular fluorane-leuco dye. This sheet provides an intense clear image less discoloration and superior heat-resistant preservability. |
