A heat-sensitive recording material comprises a base sheet and a colour developing layer formed on at least one surface of said base sheet, said colour developing layer comprising colour former and acceptor which is reactive with said colour former to develop a colour, said colour developing layer having a surface roughness of an Ra smaller than 1.2 microns and a gloss smaller than 25%. The material may be made by preparing a coating composition comprising finely divided particulate colour former material, finely divided particulate acceptor to develop a colour, and a binder, blade coating said composition on at least one surface of a base sheet to form a colour developing layer, and subjecting the surface of said layer to a calendering treatment layer. The colour developing layer may contain an oil absorptive pigment e.g. diatomaceous earth, aluminium oxide, anhydride, TiO2, white carbon, magnesium carbonate, SiO2, magnesium aluminosilicate, particle size 6-20 mu . |
