Abstract
The present invention provides a heat-sensitive recording material that suffers no defective coating and is superior in color-exhibiting sensitivity, image quality, and chemical resistance. The heat-sensitive recording material successively comprising, on a support, an undercoat layer, a heat-sensitive recording layer containing a leuco dye and a developer, and a protective layer, wherein the heat-sensitive recording layer contains, as a main pigment, kaolin having an average particle diameter of 0.1 to 0.4 μm measured by a sedimentation method in an amount of 4 to 60 mass % based on a total solids content of the heat-sensitive recording layer, and wherein the heat-sensitive recording layer and the protective layer are formed by applying a heat-sensitive recording layer coating composition and a protective layer coating composition by a simultaneous multilayer curtain coating method, and drying resulting coatings.
