<p>A recording material contains in a color forming layer a colorless electron donating dye precursor (e.g. a fluoran), an electron-accepting developer (e.g. a phenol) and 0.1 - 15 g/m<2> of a compound of formula (I) and/or (II) Ar1XCnH2nYCmH2mZAr2 (I) wherein Ar1 and Ar2 each represents an aromatic ring which may contain an O or S atom: X represents -O-, -S- and Y is -O-, -S- or -CO2- when Z is -CO-; or X is -O- and Y is -CO2-, -SO2- or -SO-, when Z is -O-; and n and m each is an integer of from 1 to 6. Ar1XCnH2nYCmH2mYCnH2nXAr2 (II) wherein Ar1, Ar2, n and m are as above; X is -S- or -O-; and Y is -CO2-. The ratio of compound (I) or (II) to electron-acceptor is 1:10 to 1:0.1; the compounds may have 16-28 C atoms and melt at 70-190 DEG C. The material can be heat-sensitive, for use in a facsimile machine, to give good color images.</p> |
