PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material which is excellent in an image stability against oil and plasticizer, and also, in color-producing sensitivity. SOLUTION: For this heat-senstive recording material wherein a heat-sensitive color-producing layer is provided on a supporting body, in the heat-senstive color-producing layer, a dye precursor-containing fine composite particle which is obtained in such a manner that a solution containing a dye precursor, and a polymerized component containing at least one kind selected from dicyclohexyl methane-4, 4'-diisocyanate, and hexamethylene diisocyanate and a denatured body of the hexamethylene diisocyanate, which are jointly used with it, as a polyhydric isocyanate compound, is emulsified and dispersed in a water soluble medium and used for a polymerization reaction, is contained together with a color-developer and an adhesive. |
