Abstract

PURPOSE:To record a high density sharp image even by minute heat energy, by specifying density and the surface of Beck smoothness of a thermal color forming layer in a thermal recording material utilizing the color forming reaction between a leuco dye and a coupler. CONSTITUTION:The density of the thermal recording material provided on a support is 0.85g/cm<3> or less and the surface Beck smoothness of a thermal color forming layer is 1000sec or more. This thermal color forming layer is provided on the support, for example, by adding inorg. fine hollow particles or fine hollow plastic filler to a thermal color forming layer forming liquid and applying the resulting mixture to the support or by applying said particles or filler to the support. By setting the density of the thermal recording material to 0.85g/cm3 or less and the surface Beck smoothness of the thermal color forming layer to 1000sec or more, a heat insulating property becomes large and the surface unevenness of the thermal color forming layer is uniformized and, therefore, the heat energy from a thermal head is effectively transmitted to the thermal color forming layer and dynamic color forming sensitivity is enhanced.
