ABSTRACT:
A heat-sensitive recording composition comprising agglomerates which comprise a colorless or light-colored dye precursor, a color developer which reacts with the dye precursor upon heating to form a color, and a sensitizer and have an average diameter of 2-30 .mu.m; and a process for producing the composition are disclosed. This heat-sensitive recording composition is excellent in heat responsiveness and high in sensitivity. From the point of image stability, the agglomerates are preferably enclosed in microcapsules together with a polymer.
