    • Disclosed is a heat-sensitive recording material comprising a supporting body and a heat-sensitive recording layer formed on the supporting body and containing a dye precursor-containing composite particle and a developer. This heat-sensitive recording material is characterized in that the dye precursor-containing composite particle is obtained by dissolving a solute containing a dye precursor into a solvent containing a polyvalent isocyanate compound-containing polymerization component, then emulsifying and dispersing the thus-obtained solution into an aqueous medium, and then performing a polymerization reaction of the polyvalent isocyanate compound-containing polymerization component in the presence of a polyethylene imine having a molecular weight of 200-1,500. Also disclosed is a method for producing such a heat-sensitive recording material.
    • 公开了一种热敏记录材料,其包括支撑体和形成在支撑体上并含有含染料前体的复合颗粒和显影剂的热敏记录层。 该热敏记录材料的特征在于,含有染料前体的复合颗粒是通过将含有染料前体的溶质溶解在含有多价异氰酸酯化合物的聚合组分的溶剂中,然后将所得溶液乳化并分散 水性介质,然后在分子量为200-1,500的聚乙烯亚胺的存在下进行含多价异氰酸酯化合物的聚合组分的聚合反应。 还公开了制造这种热敏记录材料的方法。
