    • A heat-sensitive recording material comprising a heat-sensitive color forming layer on a base is disclosed. The color forming layer contains an electron donating colorless dye and an organic acid to which a heat-fusible substance having a melting point in the range of from 60.degree. to 150.degree. C. is fusion-bonded. A process for producing such recording material by applying to a base a coating solution containing a developer for heat-sensitive recording is also disclosed. The developer is prepared by the steps of dispersing in a dispersion medium a heat-fusible substance having a melting point in the range of from 60.degree. C. to 150.degree. C. and an organic acid, heating the resulting dispersion under conditions that form a turbulent flow, and cooling the heated dispersion to ordinary temperatures.
