    Abstract: A heat-sensitive recording material which has a high recording density, ensures recorded images of high quality and allows printing on the reverse side. A base paper for the recording material is subjected to multilayer paper making by means of a paper machine having a multilayer head box. The surface layer of the base paper has a bulk density of below 0.85 g/cu. cm and a printing smoothness of above 15% (pressure: 20 kg/sq. cm) as measured by means of a printing smoothness tester.

    Abstract: Disclosed is a two-color heat-sensitive recording material which comprises a base sheet and a recording layer of single-layer or multi-layer structure formed on the base sheet, the recording layer comrising:(a) a diazonium salt,(b) a basic leuco dye,(c) a 2-hydroxy-3-naphthoic acid derivative which acts as a coupler compound for causing the diazonium salt to develop color when heated and which also acts as a color developing material for causing the basic leuco dye to develop color when heated, and(d) a basic substance, wherein the diazonium salt and the basic leuco dye each form a color upon application of heat, thereby giving the first image of a mixed color, and, then, after irradiation of an active ray to decompose the diazonium salt, the basic leuco dye alone forms its own color upon application of heat, thereby giving the second image whose color is different from the mixed color of the first image.
