ABSTRACT:
A heat-sensitive recording material is disclosed which comprises a support sheet of 5-40.mu. in thickness having thereon a heat-sensitive transfer layer containing a phenolic material, a colorless or pale-colored chromogenic material which forms a color with said phenolic material upon application of heat and a heat fusible material having a melting point of 40.degree.-150.degree. C. and an image receiving sheet superposed on the surface of said layer which are made into one integral sheet by pressing. Using this recording material, sufficiently high density of record can be obtained even by low heat energy, and the background (non-record portion) forms substantially no color to result in high contrast of record.
