PROBLEM TO BE SOLVED: To provide a microcapsule containing liquid in which the aggregation of the microcapsule after a heat-sensitive recording liquid is regulated can be prevented and a method for manufacturing the same and to provide the heat-sensitive recording material manufactured by using the heat-sensitive recording layer containing the microcapsule containing liquid and having excellent color developing density and glossiness. SOLUTION: The method for manufacturing the microcapsule containing liquid comprises the steps of adding a diazonium salt compound and a microcapsule wall precursor to a water soluble polymer water solution, emulsifying the mixture, polymerizing the microcapsule wall precursor, forming the microcapule wall, and then adding an anionic surfactant to the microcapsule wall. The heat-sensitive recording material is manufactured by using the heat- sensitive recording layer liquid containing a coupler dispersion containing a coupler compound for color developing in reaction of the microcapsule containing liquid with the diazonium salt compound. |
