ABSTRACT:
A heat-sensitive recording composition comprising a normally colorless or pale-colored chromogenic substance, a phenolic substance capable of developing the color of said chromogenic substance at an elevated temperature, and a water-soluble binder is not water resistant, but when incorporated with a compound having 2 to 10 1,2-epoxy ring structures ##EQU1## in one molecule as a hardner for said binder, the composition is rendered highly water resistant. Further, a coating liquid containing the said composition is prevented from coloration, and a recording sheet prepared by coating the said coating liquid on a support is prevented from coloration in texture.
