Abstract: In the method for the production of a dispersion of colorless chromogenic material useful for the production of a heat-sensitive record material, a colorless chromogenic material and a heat fusible material are admixed together and heated to form a co-melt, the co-melt is dispersed in hot water having a temperature higher than the solidifying point of the co-melt to form an emulsion without causing solidification of the co-melt, and then the emulsion thus obtained is further dispersed in a water having a temperature lower than the solidification point of the co-melt to form a dispersion in which solid particles of the co-melt are dispersed.

Abstract: A heat-sensitive recording material comprised of a heat-sensitive layer on a support is disclosed. The layer comprises a colorless or pale-colored basic dye and a color developing material that, when heated, reacts with the basic dye to form a color. The color developing material is made of a compound having the general formula (I): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently represent hydrogen or a hydroxyl group.
