Abstract

PURPOSE:To obtain a heat sensitive recording material excellent in heat responsiveness and head matching by a method wherein certain ethyleneurea derivative and wax are added to a heat sensitive color developing layer so as to provide a clear developed picture without any ghost. CONSTITUTION:(A) An ethyleneurea derivative (e.g. N-cyclohexyl-N', N'-ethyleneurea) represented by the formula (where R is C6-20 alkyl, cyclohexyl), and (B) vegetable or mineral wax are added into a heat sensitive color developing layer containing colorless or light-colored leuco dyes and a phonolic acid substance or an organic acid reacting with the leuco dyes to develop color when heated, as color developing components, preferably at the ratio A:B=3:1-1:3 (weight ratio) and the ratio (color developing components):components (A+B)=1:0.5-3 (weight ratio).
