ABSTRACT:
The present invention provides a heat-sensitive recording material comprising a substrate; and at least two heat-sensitive recording layers provided on the substrate, the heat-sensitive recording layers including microcapsules encapsulating an electron-donating dye precursor, and an electron-accepting compound, which reacts with the electron-donating dye precursor to develop a color and is disposed outside of the microcapsules, wherein the microcapsules include at least two kinds of microcapsules having different glass transition temperatures. A difference between each of the glass transition temperatures of the at least two microcapsules having different glass transition temperatures is preferably in a range from 20° C. to 70° C. According to the invention, a heat-sensitive recording material, which is superior in the reproduction of the gradation of an image and enables recording at high density, is obtained.
