PURPOSE:To obtain a thermal recording material of high sensitivity which is excellent in imprinting fixability, pencil writing suitability, and scratch resistance and low in glossiness of a surface of the recording layer, by a method wherein an overcoat layer which contains a specific amount to a binder of pigment and of which an coating amount is within a specific range is established on a thermal recording layer which contains a color coupler, a color agent coloring by coming in contact with the color coupler, and a pigment of a specific absorption oil amount and a specific average particle size. CONSTITUTION:This thermal recording material is formed by establishing an overcoat layer which contains 0.5 to 3.0wt% to 1wt% a binder of a pigment and of which a coating amount is 0.3 to 2.0g/m<2> on a thermal recording layer which contains a color coupler, a color agent coloring by coming in contact with the color coupler, and a pigment of which an absorption oil amount is 80 to 400ml/100g and 3 to 15mum in average particle diameter. As a combination of the color coupler and the color agent which constructs the thermal recording layer, for instance, a combination of colorless or light color basic dye and an acidic substance, a combination of higher fatty acid metallic salt such as ferric stearate or the like, a phenol group like gallic acid and, further, a combination of diazo compound and coupler compound, etc. are mentioned. |
