<p>The present invention relates to a thermosensitive recording material of heat fixing type. The thermosensitive recording material comprises, on a sheet substrate, a subbing layer and a thermosensitive color image-forming layer in this order, the thermosensitive color image-forming layer comprising a colorless or light-colored dye precursor and a color-developer which reacts with the dye precursor to color the precursor when the color-developer is heated, the color-developer being selected such that the color image formed has a high solvent resistance after the coloring, and the subbing layer comprising a color developability reducing substance capable of reducing the color-developing function of the color-developer and having a melting point of 40 DEG C or higher. According to the present invention, a thermosensitive recording material is provided, which has a good fixing property and particularly an excellent legibility of colored images even after accidental heating. The present invention also provides a method of fixing the thermosensitive recording material by heating it to 40 DEG C or higher, after the thermal printing thereof.</p> |
