PURPOSE:To obtain the thermal recording material excellent in head matching property by making polyimido resin and paraffin wax contained in a thermodeveloped layer and a supporting body and in between these substances. CONSTITUTION:The polyimido resin and paraffin wax are made contained at least in one or more of (A) the thermodeveloped layer containing colorless or lightly- colored color forming material (e.g. crystal violet lactone, etc.) and color-developing material developing the color of the color forming material by heating (e.g. bisphenol A, etc.), (B) the supporting body such as high-quality paper and in between the constituents A and B. So as to use these resin and wax, such a method that these substances are made contained beforehand in the supporting body, or that these are applied to the surface of the supporting body after being dispersed in a solvent, or that they are added to a developed layer forming liquid, may be adopted. These methods may be adopted together. EFFECT:Sticking of refuse and abrasion of the thermal head and the like are little. |
