Abstract

PURPOSE:To obtain the heat sensitive recording material wherein specified compounds, tin stearate, or the like are included in a heat sensitive coloring layer comprising a leuco dye and an acidic material, and which can endure record printing for the long period, has the excellent running property, and does not yield pressure coloring and fog. CONSTITUTION:The heat sensitive coloring layer forming liuquid is prepared by the leuco dye A which with no color or hypochromic color (e.g. Crystal Violet lactone or the like), the acidic material B which colors the component A by heating (e.g. bisphenol A or the like). 0.5-5pts.wt. (basing on 1 part of the compnent A) of one or more kinds of compounds C (e.g. 4-hydroxy benzoic acid phenylester or the like) in formulasIand II (where X is halogen; Y is alkyl, alkoxy, halogen, or the like; n=0-3; m=1-3; R1 and R2 are H, alkyl, alkoxy, or the like), and 0.1-2pts. (basing on 1 part of the component C) of tin stearate or zinc stearate D. Said liquid is applied on the supporting body.
