    • A light-sensitive heat-sensitive recording material is disclosed, which contains microcapsules resulting from a solution containing at least one component capable of undergoing color development or achromatization as a core material of the microcapsules and a volatile solvent which has a water solubility of 10% by volume or less and has a low boiling point such that it volatilizes during a process for preparing said light-sensitive heat-sensitive recording material leaving substantially no trace of the solvent in the resulting recording material. As the microcapsules, ones having a mean particle size of 2 .mu.m or less are preferred, and ones prepared using a modified gelatin as a protective colloid are also preferred. Further, as the support of the light-sensitive heat-sensitive recording material, a polyester support filled with a white pigment can preferably be used.
