Abstract
Disclosed herein is a process for producing a sheet of a color-developer for a pressure-sensitive recording paper, which process comprises the steps of dissolving an organic color-developer in an organic solvent, dispersing the formed solution into water, thereby forming minute liquid droplets with a diameter of 0.01 to 2 .mu.m, removing the solvent in the liquid droplets by heating while taking care not to cause any coalescence of the droplets and also any unstabilization of the emulsion, thereby forming a slurry comprising the minute granules of the color-developer and applying the slurry on a supporting sheet.
